GENERAL DESCRIPTION
The ADSP-BF512/ADSP-BF514/ADSP-BF514F16/ADSP-
BF516/ADSP-BF518/ADSP-BF518F16 processors are members
of the Blackfin
®
family of products, incorporating the Analog
Devices/Intel Micro Signal Architecture (MSA). Blackfin pro-
cessors combine a dual-MAC state-of-the-art signal processing
engine, the advantages of a clean, orthogonal RISC-like micro-
processor instruction set, and single-instruction, multiple-data
(SIMD) multimedia capabilities into a single instruction-set
architecture.
The processors are completely code compatible with other
Blackfin processors.
By integrating a rich set of industry-leading system peripherals
and memory, Blackfin processors are the platform of choice for
next-generation applications that require RISC-like program-
mability, multimedia support, and leading-edge signal
processing in one integrated package.
PORTABLE LOW POWER ARCHITECTURE
Blackfin processors provide world-class power management
and performance. They are produced with a low power and low
voltage design methodology and feature on-chip dynamic
power management, which is the ability to vary both the voltage
and frequency of operation to significantly lower overall power
consumption. This capability can result in a substantial reduc-
tion in power consumption, compared with just varying the
frequency of operation. This allows longer battery life for
portable appliances.
SYSTEM INTEGRATION
The ADSP-BF51x processors are highly integrated system-on-a-
chip solutions for the next generation of embedded network
connected applications. By combining industry-standard inter-
faces with a high performance signal processing core, cost-
effective applications can be developed quickly, without the
need for costly external components. The system peripherals
include an IEEE-compliant 802.3 10/100 Ethernet MAC with
IEEE-1588 support (ADSP-BF518/ADSP-BF518F16 only), an
RSI controller, a TWI controller, two UART ports, two SPI
ports, two serial ports (SPORTs), nine general-purpose 32-bit
timers (eight with PWM capability), 3-phase PWM for motor
control, a real-time clock, a watchdog timer, and a parallel
peripheral interface (PPI).
BLACKFIN PROCESSOR CORE
As shown in Figure 2, the Blackfin processor core contains two
16-bit multipliers, two 40-bit accumulators, two 40-bit ALUs,
four video ALUs, and a 40-bit shifter. The computation units
process 8-, 16-, or 32-bit data from the register file.
The compute register file contains eight 32-bit registers. When
performing compute operations on 16-bit operand data, the
register file operates as 16 independent 16-bit registers. All
operands for compute operations come from the multiported
register file and instruction constant fields.
Each MAC can perform a 16-bit by 16-bit multiply in each
cycle, accumulating the results into the 40-bit accumulators.
Signed and unsigned formats, rounding, and saturation
are supported.
The ALUs perform a traditional set of arithmetic and logical
operations on 16-bit or 32-bit data. In addition, many special
instructions are included to accelerate various signal processing
tasks. These include bit operations such as field extract and pop-
ulation count, modulo 2
32
multiply, divide primitives, saturation
and rounding, and sign/exponent detection. The set of video
instructions include byte alignment and packing operations,
16-bit and 8-bit adds with clipping, 8-bit average operations,
and 8-bit subtract/absolute value/accumulate (SAA) operations.
The compare/select and vector search instructions are also
provided.

For certain instructions, two 16-bit ALU operations can be per-
formed simultaneously on register pairs (a 16-bit high half and
16-bit low half of a compute register). If the second ALU is used,
quad 16-bit operations are possible.
The 40-bit shifter can perform shifts and rotates and is used to
support normalization, field extract, and field deposit
instructions.
The program sequencer controls the flow of instruction execu-
tion, including instruction alignment and decoding. For
program flow control, the sequencer supports PC relative and
indirect conditional jumps (with static branch prediction), and
subroutine calls. Hardware is provided to support zero-over-
head looping. The architecture is fully interlocked, meaning that
the programmer need not manage the pipeline when executing
instructions with data dependencies.
The address arithmetic unit provides two addresses for simulta-
neous dual fetches from memory. It contains a multiported
register file consisting of four sets of 32-bit index, modify,
length, and base registers (for circular buffering), and eight
additional 32-bit pointer registers (for C-style indexed stack
manipulation).
Blackfin processors support a modified Harvard architecture in
combination with a hierarchical memory structure. Level 1 (L1)
memories are those that typically operate at the full processor
speed with little or no latency. At the L1 level, the instruction
memory holds instructions only. The two data memories hold
data, and a dedicated scratchpad data memory stores stack and
local variable information.
In addition, multiple L1 memory blocks are provided, offering a
configurable mix of SRAM and cache. The memory manage-
ment unit (MMU) provides memory protection for individual
tasks that may be operating on the core and can protect system
registers from unintended access.
The architecture provides three modes of operation: user mode,
supervisor mode, and emulation mode. User mode has
restricted access to certain system resources, thus providing a
protected software environment, while supervisor mode has
unrestricted access to the system and core resources.
The Blackfin processor instruction set has been optimized so
that 16-bit opcodes represent the most frequently used instruc-
tions, resulting in excellent compiled code density. Complex
DSP instructions are encoded into 32-bit opcodes, representing
fully featured multifunction instructions. Blackfin processors
support a limited multi-issue capability, where a 32-bit

instruction can be issued in parallel with two 16-bit instruc-
tions, allowing the programmer to use many of the core
resources in a single instruction cycle.
The Blackfin processor assembly language uses an algebraic syn-
tax for ease of coding and readability. The architecture has been
optimized for use in conjunction with the C/C++ compiler,
resulting in fast and efficient software implementations.
MEMORY ARCHITECTURE
The ADSP-BF51x processors view memory as a single unified
4G byte address space, using 32-bit addresses. All resources,
including internal memory, external memory, and I/O control
registers, occupy separate sections of this common address
space. The memory portions of this address space are arranged
in a hierarchical structure to provide a good cost/performance
balance of some very fast, low-latency on-chip memory as cache
or SRAM, and larger, lower-cost and performance off-chip
memory systems. The memory map for both internal and exter-
nal memory space is shown in Figure 3.
The on-chip L1 memory system is the highest-performance
memory available to the Blackfin processor. The off-chip mem-
ory system, accessed through the external bus interface unit
(EBIU), provides expansion with SDRAM, flash memory, and
SRAM, optionally accessing up to 132M bytes of
physical memory.
The memory DMA controller provides high bandwidth data-
movement capability. It can perform block transfers of code or
data between the internal memory and the external
memory spaces.
Internal (On-Chip) Memory
The ADSP-BF51x processors have three blocks of on-chip
memory that provide high bandwidth access to the core.
The first block is the L1 instruction memory, consisting of
48K bytes SRAM, of which 16K bytes can be configured as a
four-way set-associative cache. This memory is accessed at full
processor speed.
The second on-chip memory block is the L1 data memory, con-
sisting of up to two banks of up to 32K bytes each. Each memory
bank is configurable, offering both cache and SRAM functional-
ity. This memory block is accessed at full processor speed.
The third memory block is a 4K byte scratchpad SRAM which
runs at the same speed as the L1 memories, but is only accessible
as data SRAM and cannot be configured as cache memory.
External (Off-Chip) Memory
External memory is accessed via the EBIU. This 16-bit interface
provides a glueless connection to a bank of synchronous DRAM
(SDRAM) as well as up to four banks of asynchronous memory
devices including flash, EPROM, ROM, SRAM, and memory
mapped I/O devices.
The SDRAM controller can be programmed to interface to up
to 128M bytes of SDRAM. A separate row can be open for each
SDRAM internal bank, and the SDRAM controller supports up
to four internal SDRAM banks, improving overall performance.
The asynchronous memory controller can be programmed to
control up to four banks of devices with very flexible timing
parameters for a wide variety of devices. Each bank occupies a
1M byte segment regardless of the size of the devices used, so
that these banks are only contiguous if each is fully populated
with 1M byte of memory.
Flash Memory
The ADSP-BF51xF processors contain an SPI flash memory
within the package of the processor connected to SPI0
(Figure 4).
The SPI flash memory has a 16M bit capacity. Also included are
support for software write protection and for fast erase and
byte-program.

The processors internally connect to the flash memory die with
the SPI0SCK, SPI0SEL4 or PH8, SPI0MOSI, and SPI0MISO sig-
nals similar to an external SPI flash (for signal descriptions, see
Table 2). To further provide a secure processing environment,
these internally connected signals are not exposed outside of the
package. For this reason, programming the ADSP-BF51xF flash
memory is performed by running code on the processor and
cannot be programmed from external signals. Data transfers
between the SPI flash and the processor cannot be probed exter-
nally. The flash memory has the following additional features.
• Serial Interface Architecture—SPI compatible with Mode 0
and Mode 3
• Flexible Erase Capability—Uniform 4K Byte sectors and
uniform 64K Byte overlay blocks
• Fast Erase and Byte-Program—Chip-erase time = 11.2 s
(typical), Sector-/Block-Erase Time = 70/350 ms (typical)
Byte-Program Time = 15 μS (typical)
• Software Write Protection—Write protection through
block-protection bits in status register

One-Time Programmable Memory
The processors have 64K bits of one-time programmable non-
volatile memory that can be programmed by the developer only
once. It includes the array and logic to support read access and
programming. Additionally, its pages can be write protected.
The OTP memory allows both public and private data to be
stored on-chip. In addition to storing public and private key
data for applications requiring security, OTP allows developers
to store completely user-definable data such as customer ID,
product ID, and MAC address. Therefore, generic parts can be
supplied which are then programmed and protected by the
developer within this non-volatile memory.
I/O Memory Space
The processors do not define a separate I/O space. All resources
are mapped through the flat 32-bit address space. On-chip I/O
devices have their control registers mapped into memory-
mapped registers (MMRs) at addresses near the top of the
4G byte address space. These are separated into two smaller
blocks, one which contains the control MMRs for all core func-
tions, and the other which contains the registers needed for
setup and control of the on-chip peripherals outside of the core.
The MMRs are accessible only in supervisor mode and appear
as reserved space to on-chip peripherals.
Booting from ROM
The processors contain a small on-chip boot kernel, which con-
figures the appropriate peripheral for booting. If the processors
are configured to boot from boot ROM memory space, the pro-
cessor starts executing from the on-chip boot ROM. For more
information, see Booting Modes on Page 15.
EVENT HANDLING
The event controller handles all asynchronous and synchronous
events to the processor. The processors provide event handling
that supports both nesting and prioritization. Nesting allows
multiple event service routines to be active simultaneously.
Prioritization ensures that servicing of a higher priority event
takes precedence over servicing of a lower priority event.
The controller provides support for five different types of
events:
• Emulation—An emulation event causes the processor to
enter emulation mode, allowing command and control of
the processor through the JTAG interface.
• Reset—This event resets the processor.
• Nonmaskable Interrupt (NMI)—The NMI event can be
generated by the software watchdog timer or by the NMI
input signal to the processor. The NMI event is frequently
used as a power-down indicator to initiate an orderly shut-
down of the system.
• Exceptions—Events that occur synchronously to program
flow; that is, the exception is taken before the instruction is
allowed to complete. Conditions such as data alignment
violations and undefined instructions cause exceptions.
• Interrupts—Events that occur asynchronously to program
flow. They are caused by input signals, timers, and other
peripherals, as well as by an explicit software instruction.
Each event type has an associated register to hold the return
address and an associated return-from-event instruction. When
an event is triggered, the state of the processor is saved on the
supervisor stack.
The event controller consists of two stages, the core event con-
troller (CEC) and the system interrupt controller (SIC). The
core event controller works with the system interrupt controller
to prioritize and control all system events. Conceptually, inter-
rupts from the peripherals enter into the SIC, and are then
routed directly into the general-purpose interrupts of the CEC.
Core Event Controller (CEC)
The CEC supports nine general-purpose interrupts (IVG15–7),
in addition to the dedicated interrupt and exception events. Of
these general-purpose interrupts, the two lowest priority
interrupts (IVG15–14) are recommended to be reserved for
software interrupt handlers, leaving seven prioritized interrupt
inputs to support the peripherals of the processors. The inputs
to the CEC, identifies their names in the event vector table

(EVT), and lists their priorities are described in the
ADSP-BF51x Blackfin Processor Hardware Reference Manual
“System Interrupts” chapter.
System Interrupt Controller (SIC)
The system interrupt controller provides the mapping and rout-
ing of events from the many peripheral interrupt sources to the
prioritized general-purpose interrupt inputs of the CEC.
Although the processors provide a default mapping, the user
can alter the mappings and priorities of interrupt events by
writing the appropriate values into the interrupt assignment
registers (SIC_IARx). See the ADSP-BF51x Blackfin Processor
Hardware Reference Manual “System Interrupts” chapter for the
inputs into the SIC and the default mappings into the CEC.
The SIC allows further control of event processing by providing
three pairs of 32-bit interrupt control and status registers. Each
register contains a bit corresponding to each of the peripheral
interrupt events. For more information, see the ADSP-BF51x
Blackfin Processor Hardware Reference Manual “System Inter-
rupts” chapter.
DMA CONTROLLERS
The ADSP-BF51x processors have multiple independent DMA
channels that support automated data transfers with minimal
overhead for the processor core. DMA transfers can occur
between the processor's internal memories and any of its DMA-
capable peripherals. Additionally, DMA transfers can be accom-
plished between any of the DMA-capable peripherals and
external devices connected to the external memory interfaces,
including the SDRAM controller and the asynchronous mem-
ory controller. DMA-capable peripherals include the Ethernet
MAC, RSI, SPORTs, SPIs, UARTs, and PPI. Each individual
DMA-capable peripheral has at least one dedicated DMA
channel.
The processors’ DMA controller supports both one-dimen-
sional (1-D) and two-dimensional (2-D) DMA transfers. DMA
transfer initialization can be implemented from registers or
from sets of parameters called descriptor blocks.
The 2-D DMA capability supports arbitrary row and column
sizes up to 64K elements by 64K elements, and arbitrary row
and column step sizes up to ±32K elements. Furthermore, the
column step size can be less than the row step size, allowing
implementation of interleaved data streams. This feature is
especially useful in video applications where data can be de-
interleaved on the fly.
Examples of DMA types supported by the DMA controller
include:
• A single, linear buffer that stops upon completion
• A circular, auto-refreshing buffer that interrupts on each
full or fractionally full buffer
• 1-D or 2-D DMA using a linked list of descriptors
• 2-D DMA using an array of descriptors, specifying only the
base DMA address within a common page
In addition to the dedicated peripheral DMA channels, there are
two memory DMA channels that transfer data between the vari-
ous memories of the processor system. This enables transfers of
blocks of data between any of the memories—including external
SDRAM, ROM, SRAM, and flash memory—with minimal
processor intervention. Memory DMA transfers can be con-
trolled by a very flexible descriptor-based methodology or by a
standard register-based autobuffer mechanism.
The processors also have an external DMA controller capability
via dual external DMA request signals when used in conjunc-
tion with the external bus interface unit (EBIU). This
functionality can be used when a high speed interface is
required for external FIFOs and high bandwidth communica-
tions peripherals. It allows control of the number of data
transfers for memory DMA. The number of transfers per edge is
programmable. This feature can be programmed to allow mem-
ory DMA to have an increased priority on the external bus
relative to the core.
PROCESSOR PERIPHERALS
The ADSP-BF51x processors contain a rich set of peripherals
connected to the core via several high bandwidth buses, provid-
ing flexibility in system configuration as well as excellent overall
system performance (see Figure 2). The processors contain ded-
icated network communication modules and high speed serial
and parallel ports, an interrupt controller for flexible manage-
ment of interrupts from the on-chip peripherals or external
sources, and power management control functions to tailor the
performance and power characteristics of the processor and sys-
tem to many application scenarios.
All of the peripherals, except for the general-purpose I/O, rotary
counter, TWI, three-phase PWM, real-time clock, and timers,
are supported by a flexible DMA structure. There are also sepa-
rate memory DMA channels dedicated to data transfers
between the processor's various memory spaces, including
external SDRAM and asynchronous memory. Multiple on-chip
buses provide enough bandwidth to keep the processor core
running along with activity on all of the on-chip and external
peripherals.
Real-Time Clock
The real-time clock (RTC) provides a robust set of digital watch
features, including current time, stopwatch, and alarm. The
RTC is clocked by a 32.768 kHz crystal external to the proces-
sors. The RTC peripheral has a dedicated power supply so that it
can remain powered up and clocked even when the rest of the
processor is in a low power state. The RTC provides several pro-
grammable interrupt options, including interrupt per second,
minute, hour, or day clock ticks, interrupt on programmable
stopwatch countdown, or interrupt at a programmed alarm
time.
The 32.768 kHz input clock frequency is divided down to a 1 Hz
signal by a prescaler. The counter function of the timer consists
of four counters: a 60-second counter, a 60-minute counter, a
24-hour counter, and an 32,768-day counter.
ADSP-BF512/BF514/BF514F16/BF516/BF518/BF518F16
Rev. D | Page 9 of 68 | April 2014
When enabled, the alarm function generates an interrupt when
the output of the timer matches the programmed value in the
alarm control register. There are two alarms: The first alarm is
for a time of day. The second alarm is for a day and time of
that day.
The stopwatch function counts down from a programmed
value, with one-second resolution. When the stopwatch is
enabled and the counter underflows, an interrupt is generated.
Like the other peripherals, the RTC can wake up the processor
from sleep mode upon generation of any RTC wakeup event.
Additionally, an RTC wakeup event can wake up the processor
from deep sleep mode or cause a transition from the hibernate
state.
Connect RTC signals RTXI and RTXO with external compo-
nents as shown in Figure 5.
Watchdog Timer
The ADSP-BF51x processors include a 32-bit timer that can be
used to implement a software watchdog function. A software
watchdog can improve system availability by forcing the proces-
sor to a known state through generation of a hardware reset,
nonmaskable interrupt (NMI), or general-purpose interrupt, if
the timer expires before being reset by software. The program-
mer initializes the count value of the timer, enables the
appropriate interrupt, then enables the timer. Thereafter, the
software must reload the counter before it counts to zero from
the programmed value. This protects the system from remain-
ing in an unknown state where software, which would normally
reset the timer, has stopped running due to an external noise
condition or software error.
If configured to generate a hardware reset, the watchdog timer
resets both the core and the processor peripherals. After a reset,
software can determine if the watchdog was the source of the
hardware reset by interrogating a status bit in the watchdog
timer control register.
The timer is clocked by the system clock (SCLK) at a maximum
frequency of f
SCLK
.
Timers
There are nine general-purpose programmable timer units in
the ADSP-BF51x processors. Eight timers have an external sig-
nal that can be configured either as a pulse width modulator
(PWM) or timer output, as an input to clock the timer, or as a
mechanism for measuring pulse widths and periods of external
events. These timers can be synchronized to an external clock
input to the several other associated PF signals, an external
clock input to the PPI_CLK input signal, or to the internal
SCLK.
The timer units can be used in conjunction with the two UARTs
to measure the width of the pulses in the data stream to provide
a software auto-baud detect function for the respective serial
channels.
The timers can generate interrupts to the processor core provid-
ing periodic events for synchronization, either to the system
clock or to a count of external signals.
In addition to the eight general-purpose programmable timers,
a ninth timer is also provided. This extra timer is clocked by the
internal processor clock and is typically used as a system tick
clock for generation of operating system periodic interrupts.
3-Phase PWM
The processors integrate a flexible and programmable 3-phase
PWM waveform generator that can be programmed to generate
the required switching patterns to drive a 3-phase voltage
source inverter for ac induction (ACIM) or permanent magnet
synchronous (PMSM) motor control. In addition, the PWM
block contains special functions that considerably simplify the
generation of the required PWM switching patterns for control
of the electronically commutated motor (ECM) or brushless dc
motor (BDCM). Software can enable a special mode for
switched reluctance motors (SRM).
Features of the 3-phase PWM generation unit are:
• 16-bit center-based PWM generation unit
• Programmable PWM pulse width
• Single/double update modes
• Programmable dead time and switching frequency
•Twos-complement implementation which permits smooth
transition to full ON and full OFF states
• Possibility to synchronize the PWM generation to an exter-
nal synchronization
• Special provisions for BDCM operation (crossover and
output enable functions)
• Wide variety of special switched reluctance (SR) operating
modes
• Output polarity and clock gating control
• Dedicated asynchronous PWM shutdown signal
General-Purpose (GP) Counter
A 32-bit GP counter is provided that can sense 2-bit quadrature
or binary codes as typically emitted by industrial drives or man-
ual thumb wheels. The counter can also operate in

general-purpose up/down count modes. Then, count direction
is either controlled by a level-sensitive input signal or by two
edge detectors.
A third input can provide flexible zero marker support and can
alternatively be used to input the push-button signal of thumb
wheels. All three signals have a programmable debouncing
circuit.
An internal signal forwarded to the GP timer unit enables one
timer to measure the intervals between count events. Boundary
registers enable auto-zero operation or simple system warning
by interrupts when programmable count values are exceeded.
Serial Ports
The ADSP-BF51x processors incorporate two dual-channel syn-
chronous serial ports (SPORT0 and SPORT1) for serial and
multiprocessor communications. The SPORTs support the fol-
lowing features:
Serial port data can be automatically transferred to and from
on-chip memory/external memory via dedicated DMA chan-
nels. Each of the serial ports can work in conjunction with
another serial port to provide TDM support. In this configura-
tion, one SPORT provides two transmit signals while the other
SPORT provides the two receive signals. The frame sync and
clock are shared.
Serial ports operate in five modes:
• Standard DSP serial mode
• Multichannel (TDM) mode
•I
2
S mode
•Packed I
2
S mode
•Left-justified mode
Serial Peripheral Interface (SPI) Ports
The processors have two SPI-compatible ports (SPI0 and SPI1)
that enable the processor to communicate with multiple SPI-
compatible devices.
The SPI interface uses three signals for transferring data: two
data signals (master output-slave input–MOSI, and master
input-slave output–MISO) and a clock signal (serial
clock–SCK). An SPI chip select input signal (SPIxSS) lets other
SPI devices select the processor, and multiple SPI chip select
output signals let the processor select other SPI devices. The SPI
select signals are reconfigured general-purpose I/O signals.
Using these signals, the SPI port provides a full-duplex, syn-
chronous serial interface, which supports both master/slave
modes and multimaster environments.
The SPI port baud rate and clock phase/polarities are program-
mable, and it has an integrated DMA channel, configurable to
support transmit or receive data streams. The SPI’s DMA chan-
nel can only service unidirectional accesses at any given time.
UART Ports
The processors provide two full-duplex universal asynchronous
receiver/transmitter (UART) ports, which are fully compatible
with PC-standard UARTs. Each UART port provides a
simplified UART interface to other peripherals or hosts, sup-
porting full-duplex, DMA-supported, asynchronous transfers of
serial data. A UART port includes support for five to eight data
bits, and none, even, or odd parity. Optionally, an additional
address bit can be transferred to interrupt only addressed nodes
in multi-drop bus (MDB) systems. A frame is terminates by one,
one and a half, two or two and a half stop bits.
The UART ports support automatic hardware flow control
through the Clear To Send (CTS) input and Request To Send
(RTS) output with programmable assertion FIFO levels.
To help support the Local Interconnect Network (LIN) proto-
cols, a special command causes the transmitter to queue a break
command of programmable bit length into the transmit buffer.
Similarly, the number of stop bits can be extended by a pro-
grammable inter-frame space.
The capabilities of the UARTs are further extended with sup-
port for the Infrared Data Association (IrDA®) serial infrared
physical layer link specification (SIR) protocol.
2-Wire Interface (TWI)
The processors include a TWI module for providing a simple
exchange method of control data between multiple devices. The
TWI is compatible with the widely used I
2
C
®
bus standard. The
TWI module offers the capabilities of simultaneous master and
slave operation, support for both 7-bit addressing and multime-
dia data arbitration. The TWI interface utilizes two signals for
transferring clock (SCL) and data (SDA) and supports the pro-
tocol at speeds up to 400k bits/sec. The TWI interface signals
are compatible with 5 V logic levels.
Additionally, the processor’s TWI module is fully compatible
with serial camera control bus (SCCB) functionality for easier
control of various CMOS camera sensor devices.
Removable Storage Interface (RSI)
The RSI controller, available on the ADSP-BF514/ADSP-
BF514F16/ADSP-BF516/ADSP-BF518/ADSP-BF518F16 pro-
cessors, acts as the host interface for multi-media cards (MMC),
secure digital memory cards (SD Card), secure digital
input/output cards (SDIO), and CE-ATA hard disk drives. The
following list describes the main features of the RSI controller.
• Support for a single MMC, SD memory, SDIO card or CE-
ATA hard disk drive
• Support for 1-bit and 4-bit SD modes
• Support for 1-bit, 4-bit and 8-bit MMC modes
• Support for 4-bit and 8-bit CE-ATA hard disk drives
• A ten-signal external interface with clock, command, and
up to eight data lines
• Card detection using one of the data signals
• Card interface clock generation from SCLK
• SDIO interrupt and read wait features
• CE-ATA command completion signal recognition and
disable

10/100 Ethernet MAC
The ADSP-BF516 and ADSP-BF518/ADSP-BF518F16 proces-
sors offer the capability to directly connect to a network by way
of an embedded fast Ethernet media access controller (MAC)
that supports both 10-BaseT (10M bits/sec) and 100-BaseT
(100M bits/sec) operation. The 10/100 Ethernet MAC periph-
eral on the processor is fully compliant to the IEEE 802.3-2002
standard and it provides programmable features designed to
minimize supervision, bus use, or message processing by the
rest of the processor system.
Some standard features are:
• Support of MII and RMII protocols for external PHYs
• Full duplex and half duplex modes

lision and contention handling, including control of
retransmission of collision frames and of back-off timing
• Flow control (in full-duplex operation): generation and
detection of pause frames

for read-write access to PHY registers
• Operating range for active and sleep operating modes, see

• Internal loopback from transmit to receive
Some advanced features are:
• Buffered crystal output to external PHY for support of a
single crystal system

payload fields of Rx frames
• Independent 32-bit descriptor-driven receive and transmit
DMA channels
• Frame status delivery to memory through DMA, including

transfer of receive and transmit frames and status to/from
external memory via DMA during low power sleep mode
• System wakeup from sleep operating mode upon magic
packet or any of four user-definable wakeup frame filters
• Support for 802.3Q tagged VLAN frames
• Programmable MDC clock rate and preamble suppression
• In RMII operation, seven unused signals may be config-
ured as GPIO signals for other purposes
IEEE 1588 Support
The IEEE 1588 standard is a precision clock synchronization
protocol for networked measurement and control systems. The
ADSP-BF518/ADSP-BF518F16 processors include hardware
support for IEEE 1588 with an integrated precision time proto-
col synchronization engine (PTP_TSYNC). This engine
provides hardware assisted time stamping to improve the accu-
racy of clock synchronization between PTP nodes. The main
features of the PTP_SYNC engine are:
• Support for both IEEE 1588-2002 and IEEE 1588-2008 pro-
tocol standards
• Hardware assisted time stamping capable of up to 12.5 ns
resolution
•Lock adjustment
• Programmable PTM message support
• Dedicated interrupts
• Programmable alarm
• Multiple input clock sources (SCLK, MII clock, external
clock)
• Programmable pulse per second (PPS) output
• Auxiliary snapshot to time stamp external events
Ports
Because of the rich set of peripherals, the processors group the
many peripheral signals to four ports—port F, port G, port H,
and port J. Most of the associated pins/balls are shared by multi-
ple signals. The ports function as multiplexer controls.
General-Purpose I/O (GPIO)
The ADSP-BF51x processors have 40 bidirectional, general-
purpose I/O (GPIO) signals allocated across three separate
GPIO modules—PORTFIO, PORTGIO, and PORTHIO, associ-
ated with Port F, Port G, and Port H, respectively. Each
GPIO-capable signal shares functionality with other peripherals
via a multiplexing scheme; however, the GPIO functionality is
the default state of the device upon power-up. Neither GPIO
output nor input drivers are active by default. Each general-pur-
pose port signal can be individually controlled by manipulation
of the port control, status, and interrupt registers.

ADSP-BF512/BF514/BF514F16/BF516/BF518/BF518F16
Parallel Peripheral Interface (PPI)
The ADSP-BF51x processors provide a parallel peripheral inter-
face (PPI) that can connect directly to parallel analog-to-digital
and digital-to-analog converters, ITU-R-601/656 video encod-
ers and decoders, and other general-purpose peripherals. The
PPI consists of a dedicated input clock signal, up to three frame
synchronization signals, and up to 16 data signals.
In ITU-R-656 modes, the PPI receives and parses a data stream
of 8-bit or 10-bit data elements. On-chip decode of embedded
preamble control and synchronization information
is supported.
Three distinct ITU-R-656 modes are supported:
• Active video only mode—The PPI does not read in any
data between the End of Active Video (EAV) and Start of
Active Video (SAV) preamble symbols, or any data present
during the vertical blanking intervals. In this mode, the
control byte sequences are not stored to memory; they are
filtered by the PPI.
• Vertical blanking only mode—The PPI only transfers verti-
cal blanking interval (VBI) data, as well as horizontal
blanking information and control byte sequences on
VBI lines.
• Entire field mode—The entire incoming bitstream is read
in through the PPI. This includes active video, control pre-
amble sequences, and ancillary data that may be embedded
in horizontal and vertical blanking intervals.
Though not explicitly supported, ITU-R-656 output functional-
ity can be achieved by setting up the entire frame structure
(including active video, blanking, and control information) in
memory and streaming the data out the PPI in a frame sync-less
mode. The processor’s 2-D DMA features facilitate this transfer
by allowing the static frame buffer (blanking and control codes)
to be placed in memory once, and simply updating the active
video information on a per-frame basis.
The general-purpose modes of the PPI are intended to suit a
wide variety of data capture and transmission applications. The
modes are divided into four main categories, each allowing up
to 16 bits of data transfer per PPI_CLK cycle:
• Data receive with internally generated frame syncs
• Data receive with externally generated frame syncs
• Data transmit with internally generated frame syncs
• Data transmit with externally generated frame syncs
These modes support ADC/DAC connections, as well as video
communication with hardware signalling. Many of the modes
support more than one level of frame synchronization. If
desired, a programmable delay can be inserted between asser-
tion of a frame sync and reception/transmission of data.
Code Security with Lockbox Secure Technology
A security system consisting of a blend of hardware and soft-
ware provides customers with a flexible and rich set of code
security features with Lockbox
®
secure technology. Key features
include:
• OTP memory
• Unique chip ID
• Code authentication
• Secure mode of operation
The security scheme is based upon the concept of authentica-
tion of digital signatures using standards-based algorithms and
provides a secure processing environment in which to execute
code and protect assets.
DYNAMIC POWER MANAGEMENT
The ADSP-BF51x processors provide four operating modes,
each with a different performance/power profile. In addition,
dynamic power management provides the control functions to
dynamically alter the processor core supply voltage, further
reducing power dissipation. When configured for a 0 V core
supply voltage, the processor enters the hibernate state. Control
of clocking to each of the processor peripherals also reduces
power consumption. See Table 3 for a summary of the power
settings for each mode.
Full-On Operating Mode—Maximum Performance
In the full-on mode, the PLL is enabled and is not bypassed,
providing capability for maximum operational frequency. This
is the power-up default execution state in which maximum per-
formance can be achieved. The processor core and all enabled
peripherals run at full speed.
Active Operating Mode—Moderate Power Savings
In the active mode, the PLL is enabled but bypassed. Because the
PLL is bypassed, the processor’s core clock (CCLK) and system
clock (SCLK) run at the input clock (CLKIN) frequency. In this
mode, the CLKIN to CCLK multiplier ratio can be changed,
although the changes are not realized until the full-on mode is
entered. DMA access is available to appropriately configured
L1 memories.

Rev. D | Page 13 of 68 | April 2014
In the active mode, it is possible to disable the PLL through the
PLL control register (PLL_CTL). If disabled, the PLL must be
re-enabled before transitioning to the full-on or sleep modes.
Sleep Operating Mode—High Dynamic Power Savings
The sleep mode reduces dynamic power dissipation by disabling
the clock to the processor core (CCLK). The PLL and system
clock (SCLK), however, continue to operate in this mode. Typi-
cally an external event or RTC activity wakes up the processor.
When in the sleep mode, asserting wakeup causes the processor
to sense the value of the BYPASS bit in the PLL control register
(PLL_CTL). If BYPASS is disabled, the processor transitions to
the full on mode. If BYPASS is enabled, the processor transi-
tions to the active mode.
System DMA access to L1 memory is not supported in
sleep mode.
Deep Sleep Operating Mode—Maximum Dynamic Power
Savings
The deep sleep mode maximizes dynamic power savings by dis-
abling the clocks to the processor core (CCLK) and to all
synchronous peripherals (SCLK). Asynchronous peripherals,
such as the RTC, may still be running but cannot access internal
resources or external memory. This powered-down mode can
only be exited by assertion of the reset interrupt (RESET) or by
an asynchronous interrupt generated by the RTC. When in deep
sleep mode, an RTC asynchronous interrupt causes the proces-
sor to transition to the Active mode. Assertion of RESET while
in deep sleep mode causes the processor to transition to the full
on mode.
Hibernate State—Maximum Static Power Savings
The hibernate state maximizes static power savings by disabling
the voltage and clocks to the processor core (CCLK) and system
blocks (SCLK). Any critical information stored internally (for
example memory contents, register contents) must be written to
a non-volatile storage device prior to removing power if the
processor state is to be preserved. Writing b#00 to the FREQ bits
in the VR_CTL register also causes the EXT_WAKE signal to
transition low, which can be used to signal an external voltage
regulator to shut down.
Since V
DDEXT
is still supplied in this mode, all of the external sig-
nals three-state, unless otherwise specified. This allows other
devices that may be connected to the processor to still have
power applied without drawing unwanted current.
The Ethernet module can signal an external regulator to wake
up using the EXT_WAKE signal. If PF15 does not connect as a
PHYINT signal to an external PHY device, it can be pulled low
by any other device to wake the processor up. The processor can
also be woken up by a real-time clock wakeup event or by assert-
ing the RESET pin. All hibernate wakeup events initiate the
hardware reset sequence. Individual sources are enabled by the
VR_CTL register. The EXT_WAKE signal is provided to indi-
cate the occurrence of wakeup events.
With the exception of the VR_CTL and the RTC registers, all
internal registers and memories lose their content in the hiber-
nate state. State variables may be held in external SRAM or
SDRAM. The SCKELOW bit in the VR_CTL register controls
whether or not SDRAM operates in self-refresh mode, which
allows it to retain its content while the processor is in hiberna-
tion and through the subsequent reset sequence.
Power Savings
As shown in Table 4, the processors support up to six different
power domains, which maximizes flexibility while maintaining
compliance with industry standards and conventions. By isolat-
ing the internal logic of the processor into its own power
domain, separate from the RTC and other I/O, the processor
can take advantage of dynamic power management without
affecting the RTC or other I/O devices. There are no sequencing
requirements for the various power domains, but all domains
must be powered according to the appropriate Specifications
table for processor Operating Conditions; even if the fea-
ture/peripheral is not used.
The dynamic power management feature of the processor
allows both the processor’s input voltage (V
DDINT
) and clock fre-
quency (f
CCLK
) to be dynamically controlled.
The power dissipated by a processor is largely a function of its
clock frequency and the square of the operating voltage. For
example, reducing the clock frequency by 25% results in a 25%
reduction in dynamic power dissipation, while reducing the
voltage by 25% reduces dynamic power dissipation by more
than 40%. Further, these power savings are additive, in that if
the clock frequency and supply voltage are both reduced, the
power savings can be dramatic, as shown in the following
equations.

VOLTAGE REGULATION INTERFACE
The ADSP-BF51x processors require an external voltage regula-
tor to power the V
DDINT
domain. To reduce standby power
consumption in the hibernate state, the external voltage regula-
tor can be signaled through EXT_WAKE to remove power from
the processor core. The EXT_WAKE signal is high-true for
power-up and may be connected directly to the low-true shut
down input of many common regulators.
The Power Good (PG) input signal allows the processor to start
only after the internal voltage has reached a chosen level. In this
way, the startup time of the external regulator is detected after
hibernation. For a complete description of the PG functionality,
refer to the ADSP-BF51x Blackfin Processor Hardware Reference.
CLOCK SIGNALS
The ADSP-BF51x processors can be clocked by an external crys-
tal, a sine wave input, or a buffered, shaped clock derived from
an external clock oscillator.
If an external clock is used, it should be a TTL compatible signal
and must not be halted, changed, or operated below the speci-
fied frequency during normal operation. This signal is
connected to the processor CLKIN signal. When an external
clock is used, the XTAL pin/ball must be left unconnected.
Alternatively, because the processor includes an on-chip oscilla-
tor circuit, an external crystal may be used. For fundamental
frequency operation, use the circuit shown in Figure 6. A paral-
lel-resonant, fundamental frequency, microprocessor-grade
crystal is connected across the CLKIN and XTAL pins/balls. The
on-chip resistance between the CLKIN pin/ball and the XTAL
pin/ball is in the 500 kΩ range. Further parallel resistors are typ-
ically not recommended. The two capacitors and the series
resistor shown in Figure 6 fine tune phase and amplitude of the
sine frequency.
The capacitor and resistor values shown in Figure 6 are typical
values only. The capacitor values are dependent upon the crystal
manufacturers’ load capacitance recommendations and the PCB
physical layout. The resistor value depends on the drive level
specified by the crystal manufacturer. The user should verify the
customized values based on careful investigations on multiple
devices over temperature range.
A third-overtone crystal can be used for frequencies above
25 MHz. The circuit is then modified to ensure crystal operation
only at the third overtone, by adding a tuned inductor circuit as
shown in Figure 6. A design procedure for third-overtone oper-
ation is discussed in detail in application note (EE-168) Using
Third Overtone Crystals with the ADSP-218x DSP on the Analog
Devices website (www.analog.com)—use site search on
“EE-168.”
The CLKBUF signal is an output signal, which is a buffered ver-
sion of the input clock. This signal is particularly useful in
Ethernet applications to limit the number of required clock
sources in the system. In this type of application, a single
25 MHz or 50 MHz crystal may be applied directly to the pro-
cessor. The 25 MHz or 50 MHz output of CLKBUF can then be
connected to an external Ethernet MII or RMII PHY device.
The Blackfin core runs at a different clock rate than the on-chip
peripherals. As shown in Figure 7, the core clock (CCLK) and
system peripheral clock (SCLK) are derived from the input
clock (CLKIN) signal. An on-chip PLL is capable of multiplying
the CLKIN signal by a programmable 5× to 64× multiplication
factor (bounded by specified minimum and maximum VCO
frequencies). The default multiplier is 6×, but it can be modified
by a software instruction sequence.
On-the-fly frequency changes can be done simply by writing to
the PLL_DIV register. The maximum allowed CCLK and SCLK
rates depend on the applied voltages V
DDINT
, V
DDEXT
, and
V
DDMEM
, and the VCO is always permitted to run up to the fre-
quency specified by the part’s speed grade. The CLKOUT signal
reflects the SCLK frequency to the off-chip world. It belongs to
the SDRAM interface, but it functions as a reference signal in
other timing specifications as well. While active by default, it
can be disabled using the EBIU_SDGCTL and EBIU_AMGCTL
registers.

All on-chip peripherals are clocked by the system clock (SCLK).
The system clock frequency is programmable by means of the
SSEL3–0 bits of the PLL_DIV register. The values programmed
into the SSEL fields define a divide ratio between the PLL output
(VCO) and the system clock. SCLK divider values are 1 through
15. Table 5 illustrates typical system clock ratios.
Note that the divisor ratio must be chosen to limit the system
clock frequency to its maximum of f
SCLK
. The SSEL value can be
changed dynamically without any PLL lock latencies by writing
the appropriate values to the PLL divisor register (PLL_DIV).
The core clock (CCLK) frequency can also be dynamically
changed by means of the CSEL1–0 bits of the PLL_DIV register.
Supported CCLK divider ratios are 1, 2, 4, and 8, as shown in
Table 6. This programmable core clock capability is useful for
fast core frequency modifications.
The maximum CCLK frequency not only depends on the part's
speed grade (see Page 67), it also depends on the applied V
DDINT
voltage. See Table 10 on Page 23 for details. The maximal sys-
tem clock rate (SCLK) depends on the chip package and the
applied V
DDINT
, V
DDEXT
, and V
DDMEM
voltages (see Table 12 on
Page 23).
BOOTING MODES
The processor has several mechanisms (listed in Table 7) for
automatically loading internal and external memory after a
reset. The boot mode is defined by three BMODE input bits
dedicated to this purpose. There are two categories of boot
modes. In master boot modes the processor actively loads data
from parallel or serial memories. In slave boot modes the pro-
cessor receives data from external host devices.
The boot modes listed in Table 7 provide a number of mecha-
nisms for automatically loading the processor’s internal and
external memories after a reset. By default, all boot modes use
the slowest meaningful configuration settings. Default settings
can be altered via the initialization code feature at boot time or
by proper OTP programming at pre-boot time. The BMODE
bits of the reset configuration register, sampled during power-
on resets and software-initiated resets, implement the modes
shown in Table 7.
• Idle/no boot mode (BMODE = 0x0)—In this mode, the
processor goes into idle. The idle boot mode helps recover
from illegal operating modes, such as when the user has
mis configured the OTP memory.
• Boot from 8-bit or 16-bit external flash memory
(BMODE = 0x1)—In this mode, the boot kernel loads the
first block header from address 0x2000 0000 and—depend-
ing on instructions containing in the header—the boot
kernel performs 8-bit or 16-bit boot or starts program exe-
cution at the address provided by the header. By default, all
configuration settings are set for the slowest device possible
(3-cycle hold time, 15-cycle R/W access times, 4-cycle
setup).
The ARDY is not enabled by default, but it can be enabled
by OTP programming. Similarly, all interface behavior and
timings can be customized by OTP programming. This
includes activation of burst-mode or page-mode operation.
In this mode, all signals belonging to the asynchronous
interface are enabled at the port muxing level.
• Boot from internal SPI memory (BMODE = 0x2)—The
processor uses the internal PH8 GPIO signal to load code
previously loaded to the 16M bit internal SPI flash con-
nected to SPI0. Only available on the ADSP-BF51xF
processors.
• Boot from external SPI EEPROM or flash
(BMODE = 0x3)—8-bit, 16-bit, 24-bit or 32-bit address-
able devices are supported. The processor uses the PG15
GPIO signal (at SPI0SEL2) to select a single SPI
EEPROM/flash device connected to the SPI0 interface;
then submits a read command and successive address bytes
(0x00) until a valid 8-, 16-, 24-, or 32-bit addressable device
is detected. Pull-up resistors are required on the SSEL and
MISO signals. By default, a value of 0x85 is written to the
SPI0_BAUD register.

• Boot from SPI0 host device (BMODE = 0x4)—The proces-
sor operates in SPI slave mode and is configured to receive
the bytes of the LDR file from an SPI host (master) agent.
In the host, the HWAIT signal must be interrogated by the
host before every transmitted byte. A pull-up resistor is
required on the SPI0SS input. A pull-down on the serial
clock may improve signal quality and booting robustness.
• Boot from OTP memory (BMODE = 0x5)—This provides
a stand-alone booting method. The boot stream is loaded
from on-chip OTP memory. By default the boot stream is
expected to start from OTP page 0x40 on and can occupy
all public OTP memory up to page 0xDF. This is 2560
bytes. Since the start page is programmable the maximum
size of the boot stream can be extended to 3072 bytes.
• Boot from SDRAM (BMODE = 0x6)—This is a warm boot
scenario, where the boot kernel starts booting from address
0x0000 0010. The SDRAM is expected to contain a valid
boot stream and the SDRAM controller must be configured
by the OTP settings.
•Boot from UART0 host (BMODE = 0x7)—Using an auto-
baud handshake sequence, a boot-stream formatted
program is downloaded by the host. The host selects a bit
rate within the UART clocking capabilities.
When performing the autobaud, the UART expects a “@”
(0x40) character (eight bits data, one start bit, one stop bit,
no parity bit) on the RX0 signal to determine the bit rate.
The UART then replies with an acknowledgement com-
posed of 4 bytes (0xBF—the value of UART0_DLL and
0x00—the value of UART0_DLH). The host can then
download the boot stream. To hold off the host the Blackfin
processor signals the host with the boot host wait
(HWAIT) signal. Therefore, the host must monitor
HWAIT before every transmitted byte.
For each of the boot modes, a 16-byte header is first read from
an external memory device. The header specifies the number of
bytes to be transferred and the memory destination address.
Multiple memory blocks may be loaded by any boot sequence.
Once all blocks are loaded, program execution commences from
the address stored in the EVT1 register.
Prior to booting, the pre-boot routine interrogates the OTP
memory. Individual boot modes can be customized or even dis-
abled based on OTP programming. External hardware,
especially booting hosts may watch the HWAIT signal to deter-
mine when the pre-boot has finished and the boot kernel starts
the boot process. By programming OTP memory, the user can
instruct the preboot routine to also customize the PLL, the
SDRAM Controller, and the Asynchronous Interface.
The boot kernel differentiates between a regular hardware reset
and a wakeup-from-hibernate event to speed up booting in the
later case. Bits 6-4 in the system reset configuration (SYSCR)
register can be used to bypass pre-boot routine and/or boot ker-
nel in case of a software reset. They can also be used to simulate
a wakeup-from-hibernate boot in the software reset case.
The boot process can be further customized by “initialization
code.” This is a piece of code that is loaded and executed prior to
the regular application boot. Typically, this is used to configure
the SDRAM controller or to speed up booting by managing
PLL, clock frequencies, wait states, or serial bit rates.
The boot ROM also features C-callable function entries that can
be called by the user application at run time. This enables sec-
ond-stage boot or boot management schemes to be
implemented with ease.
INSTRUCTION SET DESCRIPTION
The Blackfin processor family assembly language instruction set
employs an algebraic syntax designed for ease of coding and
readability. The instructions have been specifically tuned to pro-
vide a flexible, densely encoded instruction set that compiles to
a very small final memory size. The instruction set also provides
fully featured multifunction instructions that allow the pro-
grammer to use many of the processor core resources in a single
instruction. Coupled with many features more often seen on
microcontrollers, this instruction set is very efficient when com-
piling C and C++ source code. In addition, the architecture
supports both user (algorithm/application code) and supervisor
(O/S kernel, device drivers, debuggers, ISRs) modes of opera-
tion, allowing multiple levels of access to core
processor resources.
The assembly language, which takes advantage of the proces-
sor’s unique architecture, offers the following advantages:
• Seamlessly integrated DSP/MCU features are optimized for
both 8-bit and 16-bit operations.
• A multi-issue load/store modified-harvard architecture,
which supports two 16-bit MACs or four 8-bit ALUs plus
two load/store plus two pointer updates per cycle.
• All registers, I/O, and memory are mapped into a unified
4G byte memory space, providing a simplified program-
ming model.
• Microcontroller features, such as arbitrary bit and bit-field
manipulation, insertion, and extraction; integer operations
on 8-, 16-, and 32-bit data-types; and separate user and
supervisor stack pointers.
• Code density enhancements, which include intermixing of
16-bit and 32-bit instructions (no mode switching, no code
segregation). Frequently used instructions are encoded
in 16 bits.

KIT Lite evaluation kits. Each evaluation kit includes an EZ-KIT
Lite evaluation board, directions for downloading an evaluation
version of the available IDE(s), a USB cable, and a power supply.
The USB controller on the EZ-KIT Lite board connects to the
USB port of the user’s PC, enabling the chosen IDE evaluation
suite to emulate the on-board processor in-circuit. This permits
the customer to download, execute, and debug programs for the
EZ-KIT Lite system. It also supports in-circuit programming of
the on-board Flash device to store user-specific boot code,
enabling standalone operation. With the full version of Cross-
Core Embedded Studio or VisualDSP++ installed (sold
separately), engineers can develop software for supported EZ-
KITs or any custom system utilizing supported Analog Devices
processors.
Software Add-Ins for CrossCore Embedded Studio
Analog Devices offers software add-ins which seamlessly inte-
grate with CrossCore Embedded Studio to extend its capabilities
and reduce development time. Add-ins include board support
packages for evaluation hardware, various middleware pack-
ages, and algorithmic modules. Documentation, help,
configuration dialogs, and coding examples present in these
add-ins are viewable through the CrossCore Embedded Studio
IDE once the add-in is installed.
Board Support Packages for Evaluation Hardware
Software support for the EZ-KIT Lite evaluation boards and EZ-
Extender daughter cards is provided by software add-ins called
Board Support Packages (BSPs). The BSPs contain the required
drivers, pertinent release notes, and select example code for the
given evaluation hardware. A download link for a specific BSP is
located on the web page for the associated EZ-KIT or EZ-
Extender product. The link is found in the Product Download

Designing an Emulator-Compatible DSP Board (Target)
For embedded system test and debug, Analog Devices provides
a family of emulators. On each JTAG DSP, Analog Devices sup-
plies an IEEE 1149.1 JTAG Test Access Port (TAP). In-circuit
emulation is facilitated by use of this JTAG interface. The emu-
lator accesses the processor’s internal features via the
processor’s TAP, allowing the developer to load code, set break-
points, and view variables, memory, and registers. The
processor must be halted to send data and commands, but once
an operation is completed by the emulator, the DSP system is set
to run at full speed with no impact on system timing. The emu-
lators require the target board to include a header that supports
connection of the DSP’s JTAG port to the emulator.
For details on target board design issues including mechanical
layout, single processor connections, signal buffering, signal ter-
mination, and emulator pod logic, see the EE-68: Analog Devices
JTAG Emulation Technical Reference on the Analog Devices
website (www.analog.com)—use site search on “EE-68.” This
document is updated regularly to keep pace with improvements
to emulator support.

RELATED SIGNAL CHAINS
A signal chain is a series of signal-conditioning electronic com-
ponents that receive input (data acquired from sampling either
real-time phenomena or from stored data) in tandem, with the
output of one portion of the chain supplying input to the next.
Signal chains are often used in signal processing applications to
gather and process data or to apply system controls based on
analysis of real-time phenomena. For more information about
this term and related topics, see the "signal chain" entry in

SIGNAL DESCRIPTIONS
The processors’ signal definitions are listed in Table 8. In order
to maintain maximum function and reduce package size and
signal count, some signals have dual, multiplexed functions. In
cases where signal function is reconfigurable, the default state is
shown in plain text, while the alternate function is shown in
italics.
All pins are three-stated during and immediately after reset,
with the exception of the external memory interface, asynchro-
nous and synchronous memory control, and the buffered XTAL
output pin (CLKBUF). On the external memory interface, the
control and address lines are driven high, with the exception of
CLKOUT, which toggles at the system clock rate. During hiber-
nate all outputs are three-stated unless otherwise noted in
Table 8.
All I/O signals have their input buffers disabled with the excep-
tion of the signals noted in the data sheet that need pull-ups or
pull downs if unused.
The SDA (serial data) and SCL (serial clock) pins/balls are open
drain and therefore require a pullup resistor. Consult version
2.1 of the I
2
C specification for the proper resistor value.
It is strongly advised to use the available IBIS models to ensure
that a given board design meets overshoot/undershoot and sig-
nal integrity requirements. If no IBIS simulation is performed, it
is strongly recommended to add series resistor terminations for
all Driver Types A, C and D. The termination resistors should
be placed near the processor to reduce transients and improve
signal integrity. The resistance value, typically 33 Ω or 47 Ω,
should be chosen to match the average board trace impedance.
Additionally, adding a parallel termination to CLKOUT may
prove useful in further enhancing signal integrity. Be sure to
verify overshoot/undershoot and signal integrity specifications
on actual hardware.

When driven low, the PF15 signal can be used to wake up the processor from the hibernate state, either in normal GPIO mode or in Ethernet mode as PHYINT. If the pin/ball
is used for wake up, enable the feature with the PHYWE bit in the VR_CTL register, and pull-up the signal with a resistor.
3
Boot host wait is a GPIO signal toggled by the boot kernel. The mandatory external pull-up/pull-down resistor defines the signal polarity.
4
A pull-up resistor is required for the boot from external SPI EEPROM or flash (BMODE = 0x3).

Total Power Dissipation
Total power dissipation has two components:
1. Static, including leakage current
2. Dynamic, due to transistor switching characteristics
Many operating conditions can also affect power dissipation,
including temperature, voltage, operating frequency, and pro-
cessor activity. Electrical Characteristics on Page 24 shows the
current dissipation for internal circuitry (V
DDINT
). I
DDDEEPSLEEP
specifies static power dissipation as a function of voltage
(V
DDINT
) and temperature (see Table 14), and I
DDINT
specifies the
total power specification for the listed test conditions, including
the dynamic component as a function of voltage (V
DDINT
) and
frequency (Table 15).
There are two parts to the dynamic component. The first part is
due to transistor switching in the core clock (CCLK) domain.
This part is subject to an Activity Scaling Factor (ASF) which
represents application code running on the processor core and
L1 memories (Table 13).
The ASF is combined with the CCLK Frequency and V
DDINT
dependent data in Table 15 to calculate this part. The second
part is due to transistor switching in the system clock (SCLK)
domain, which is included in the I
DDINT
specification equation.

ABSOLUTE MAXIMUM RATINGS
Stresses greater than those listed in Table 18 may cause perma-
nent damage to the device. These are stress ratings only.
Functional operation of the device at these or any other condi-
tions greater than those indicated in the operational sections of
this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device
reliability.
When programming OTP memory on the ADSP-BF51x proces-
sor, the V
PPOTP
pin/ball must be set to the write value specified in
the Operating Conditions on Page 22. There is a finite amount
of cumulative time that the write voltage may be applied
(dependent on voltage and junction temperature) to V
PPOTP
over
the lifetime of the part. Therefore, maximum OTP memory pro-
gramming time for the processor is shown in Table 20.
Table 21 and Table 22 specify the maximum total source/sink
(I
OH
/I
OL
) current for a group of pins. Permanent damage can
occur if this value is exceeded. To understand this specification,
if pins PF9, PF8, PF7, PF6, and PF5 from Group 1 in Table 22
table were sourcing or sinking 2 mA each, the total current for
those pins would be 10 mA. This would allow up to 70 mA total
that could be sourced or sunk by the remaining pins in the
group without damaging the device. Note that the V
OH
and V
OL
specifications have separate per-pin maximum current require-
ments as shown in the Electrical Characteristics table.

TEST CONDITIONS
All timing parameters appearing in this data sheet were mea-
sured under the conditions described in this section. Figure 54
shows the measurement point for ac measurements (except out-
put enable/disable). The measurement point V
MEAS
is V
DDEXT
/2
or V
DDMEM
/2 for V
DDEXT
/V
DDMEM
(nominal) = 1.8 V/2.5 V/3.3 V.
Output Enable Time Measurement
Output signals are considered to be enabled when they have
made a transition from a high impedance state to the point
when they start driving.
The output enable time t
ENA
is the interval from the point when
a reference signal reaches a high or low voltage level to the point
when the output starts driving as shown on the right side of
Figure 55.
The time t
ENA_MEASURED
is the interval from when the reference
signal switches to when the output voltage reaches V
TRIP
(high)
or V
TRIP
(low). For V
DDEXT

Output Disable Time Measurement
Output signals are considered to be disabled when they stop
driving, go into a high impedance state, and start to decay from
their output high or low voltage. The output disable time t
DIS
is
the difference between t
DIS_MEASURED
and t
DECAY
as shown on the
left side of Figure 55.
The time for the voltage on the bus to decay by V is dependent
on the capacitive load C
L
and the load current I
L
. This decay
time can be approximated by the equation:
The time t
DECAY
is calculated with test loads C
L
and I
L
and with
V equal to 0.25 V for V
DDEXT
/V
DDMEM
(nominal) = 2.5 V/3.3 V
and 0.15 V for V
DDEXT
/
VDDMEM
(nominal) = 1.8 V.
The time t
DIS_MEASURED
is the interval from when the reference
signal switches to when the output voltage decays V from the
measured output high or output low voltage.
Example System Hold Time Calculation
To determine the data output hold time in a particular system,
first calculate t
DECAY
using the equation given above. Choose V
to be the difference between the ADSP-BF51x processor’s out-
put voltage and the input threshold for the device requiring the
hold time. C
L
is the total bus capacitance (per data line), and I
L
is
the total leakage or three-state current (per data line). The hold
time is t
DECAY
plus the various output disable times as specified
in the Timing Specifications on Page 29 (for example t
DSDAT
for
an SDRAM write cycle as shown in SDRAM Interface Timing
on Page 33).
Capacitive Loading
Output delays and holds are based on standard capacitive loads
of an average of 6 pF on all balls (see Figure 56). V
LOAD
is equal
to (V
DDEXT
/V
DDMEM
)/2. The graphs of Figure 57 through
Figure 68 show how output rise time varies with capacitance.
The delay and hold specifications given should be derated by a
factor derived from these figures. The graphs in these figures
may not be linear outside the ranges shown.

measurement complies with JESD51-8. The junction-to-case
measurement complies with MIL-STD-883 (Method 1012.1).
All measurements use a 2S2P JEDEC test board.
The LQFP_EP package requires thermal trace squares and ther-
mal vias to an embedded ground plane in the PCB. The paddle
must be connected to ground for proper operation to data sheet
specifications. Refer to JEDEC standard JESD51-5 for more
information.

NOTE: THE EXPOSED PAD IS REQUIRED TO BE ELECTRICALLY AND
THERMALLY CONNECTED TO GND. IMPLEMENT THIS BY
SOLDERING THE EXPOSED PAD TO A GND PCB LAND THAT IS
THE SAME SIZE AS THE EXPOSED PAD. THE GND PCB LAND
SHOULD BE ROBUSTLY CONNECTED TO THE GND PLANE IN
THE PCB WITH AN ARRAY OF THERMAL VIAS FOR BEST
PERFORMANCE.
