Blackfin processors combine a dualMAC state-of-the-art signal processing engine, the advantages of a clean, orthogonal RISC-like microprocessor instruction set, and single-instruction, multiple-data (SIMD) multimedia capabilities into a single instruction-set architecture. Specific performance and memory configuration is shown in Table 1. Table 1. Processor Comparison Maximum performance Instruction SRAM/Cache Instruction SRAM Data SRAM/Cache Data SRAM Scratchpad ADSP-BF534 500 MHz 16K bytes 48K bytes 32K bytes 32K bytes 4K bytes 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 programmability, multimedia support and leading-edge signal processing in one integrated package. PORTABLE LOW-POWER ARCHITECTURE Blackfin processors provide world-class power management and performance. Blackfin processors are designed in a low power and low voltage design methodology and feature on-chip Dynamic Power Management, the ability to vary both the voltage and frequency of operation to significantly lower overall power consumption. Varying the voltage and frequency can result in a substantial reduction in power consumption, compared with just varying the frequency of operation. This translates into longer battery life for portable appliances. SYSTEM INTEGRATION The ADSP-BF534 processor is a highly integrated system-on-achip solutions for the next generation of embedded network connected applications. By combining industry-standard interfaces with a high performance signal processing core, users can Rev. PrD | develop cost-effective solutions quickly without the need for costly external components. The system peripherals include a CAN 2.0B controller, a TWI controller, two UART ports, an SPI port, two serial ports (SPORTs), nine general purpose 32-bit timers (eight with PWM capability), a real-time clock, a watchdog timer, and a Parallel Peripheral Interface. ADSP-BF534 PROCESSOR PERIPHERALS The ADSP-BF534 processor contains a rich set of peripherals connected to the core via several high bandwidth buses, providing flexibility in system configuration as well as excellent overall system performance (see the block diagram on page 1). The general-purpose peripherals include functions such as UARTs, SPI, TWI, Timers with PWM (Pulse Width Modulation) and pulse measurement capability, general purpose I/O pins, a RealTime Clock, and a Watchdog Timer. This set of functions satisfies a wide variety of typical system support needs and is augmented by the system expansion capabilities of the part. The ADSP-BF534 processor contains dedicated network communication modules and high-speed serial and parallel ports, an interrupt controller for flexible management 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 system to many application scenarios. All of the peripherals, except for general-purpose I/O, CAN, TWI, Real-Time Clock, and timers, are supported by a flexible DMA structure. There are also separate memory DMA channels dedicated to data transfers between the processor's various memory spaces, including external SDRAM and asynchronous memory. Multiple on-chip buses running at up to 133 MHz provide enough bandwidth to keep the processor core running along with activity on all of the on-chip and external peripherals. The ADSP-BF534 processor includes an on-chip voltage regulator in support of the ADSP-BF534 processor Dynamic Power Management capability. The voltage regulator provides a range of core voltage levels when supplied from a single 2.25 V to 3.6 V input. The voltage regulator can be bypassed at the user's discretion. Page 3 of 60 | January 2005 ADSP-BF534 Preliminary Technical Data BLACKFIN PROCESSOR CORE As shown in Figure 2 on page 5, 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-bit, 16-bit, 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 population count, modulo 232 multiply, divide primitives, saturation and rounding, and sign/exponent detection. The set of video instructions include byte alignment and packing operations, 16bit and 8-bit adds with clipping, 8-bit average operations, and 8bit subtract/absolute value/accumulate (SAA) operations. Also provided are the compare/select and vector search instructions. For certain instructions, two 16-bit ALU operations can be performed simultaneously on register pairs (a 16-bit high half and 16-bit low half of a compute register). By also using the second ALU, 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 execution, 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-overhead 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 simultaneous 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. Rev. PrD | In addition, multiple L1 memory blocks are provided, offering a configurable mix of SRAM and cache. The Memory Management 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 instructions, 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 instructions, allowing the programmer to use many of the core resources in a single instruction cycle. The Blackfin processor assembly language uses an algebraic syntax 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-BF534 processor views 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. See Figure 3 on page 6. The on-chip L1 memory system is the highest-performance memory available to the Blackfin processor. The off-chip memory system, accessed through the External Bus Interface Unit (EBIU), provides expansion with SDRAM, flash memory, and SRAM, optionally accessing up to 516M bytes of physical memory. The memory DMA controller provides high-bandwidth datamovement 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-BF534 processor has three blocks of on-chip memory providing high-bandwidth access to the core. The first block is the L1 instruction memory, consisting of 64K 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, consisting of two banks of 32K bytes each. Each memory bank is configurable, offering both Cache and SRAM functionality. This memory block is accessed at full processor speed.

Blackfin Processor Core 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 PC133-compliant SDRAM controller can be programmed to interface to up to 512M bytes of SDRAM. A separate row can be open for each SDRAM internal bank and the SDRAM controller supports up to 4 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 will only be contiguous if each is fully populated with 1M byte of memory. I/O Memory Space smaller blocks, one which contains the control MMRs for all core functions, 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 The ADSP-BF534 processor contains a small on-chip boot kernel, which configures the appropriate peripheral for booting. If the ADSP-BF534 processor is configured to boot from boot ROM memory space, the processor starts executing from the on-chip boot ROM. For more information, see Booting Modes on page 14. Event Handling The event controller on the ADSP-BF534 processor handles all asynchronous and synchronous events to the processor. The ADSP-BF534 processor provides 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: The ADSP-BF534 processor does 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 Rev. PrD | Page 5 of 60 | * Emulation - An emulation event causes the processor to enter emulation mode, allowing command and control of the processor via the JTAG interface. * Reset - This event resets the processor. January 2005 ADSP-BF534 Preliminary Technical Data Core Event Controller (CEC) 0xFFFF FFFF CORE MMR REGISTERS (2M BYTE) 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 ADSP-BF534 processor. Table 2 describes the inputs to the CEC, identifies their names in the Event Vector Table (EVT), and lists their priorities. 0xFFE0 0000 SYSTEM MMR REGISTERS (2M BYTE) 0xFFC0 0000 RESERVED 0xFFB0 1000 SCRATCHPAD SRAM (4K BYTE) RESERVED 0xFFA1 4000 INSTRUCTION SRAM / CACHE (16K BYTE) 0xFFA1 0000 RESERVED 0xFFA0 C000 INSTRUCTION BANK B SRAM (16K BYTE) 0xFFA0 8000 INSTRUCTION BANK A SRAM (32K BYTE) 0xFFA0 0000 RESERVED 0xFF90 8000 INTERNAL MEMORY MAP 0xFFB0 0000 Table 2.

ADSP-BF534 Internal/External Memory Map * Non-Maskable 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 shutdown of the system. * Exceptions - Events that occur synchronously to program flow (i.e., the exception will be 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 pins, 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 ADSP-BF534 processor Event Controller consists of two stages, the Core Event Controller (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, interrupts from the peripherals enter into the SIC, and are then routed directly into the general-purpose interrupts of the CEC. Rev.

Although the ADSP-BF534 processor provides a default mapping, the user can alter the mappings and priorities of interrupt events by writing the appropriate values into the Interrupt Assignment Registers (IAR). Table 3 describes the inputs into the SIC and the default mappings into the CEC. Event Control The ADSP-BF534 processor provides the user with a very flexible mechanism to control the processing of events. In the CEC, three registers are used to coordinate and control events. Each register is 16 bits wide: Page 6 of 60 | * CEC Interrupt Latch Register (ILAT) - The ILAT register indicates when events have been latched. The appropriate bit is set when the processor has latched the event and cleared when the event has been accepted into the system. January 2005 Preliminary Technical Data ADSP-BF534 Table 3.

When a bit is set in the IMASK register, that event is unmasked and will be processed by the CEC when asserted. A cleared bit in the IMASK register masks the event, preventing the processor from servicing the event even though the event may be latched in the ILAT register. This register may be read or written while in supervisor mode. (Note that general-purpose interrupts can be globally enabled and disabled with the STI and CLI instructions, respectively.) * CEC Interrupt Pending Register (IPEND) - The IPEND register keeps track of all nested events. A set bit in the IPEND register indicates the event is currently active or nested at some level. This register is updated automatically by the controller but may be read while in supervisor mode. The SIC allows further control of event processing by providing three 32-bit interrupt control and status registers. Each register contains a bit corresponding to each of the peripheral interrupt events shown in Table 3 on page 7. * SIC Interrupt Mask Register (SIC_IMASK)- This register controls the masking and unmasking of each peripheral interrupt event. When a bit is set in the register, that peripheral event is unmasked and will be processed by the system when asserted. A cleared bit in the register masks the peripheral event, preventing the processor from servicing the event. * SIC Interrupt Status Register (SIC_ISR) - As multiple peripherals can be mapped to a single event, this register allows the software to determine which peripheral event Rev. PrD | Page 7 of 60 | January 2005 ADSP-BF534 Preliminary Technical Data source triggered the interrupt. A set bit indicates the peripheral is asserting the interrupt, and a cleared bit indicates the peripheral is not asserting the event. * SIC Interrupt Wakeup Enable Register (SIC_IWR) - By enabling the corresponding bit in this register, a peripheral can be configured to wake up the processor, should the core be idled when the event is generated. (For more information, see Dynamic Power Management on page 11.) Because multiple interrupt sources can map to a single generalpurpose interrupt, multiple pulse assertions can occur simultaneously, before or during interrupt processing for an interrupt event already detected on this interrupt input. The IPEND register contents are monitored by the SIC as the interrupt acknowledgement. The appropriate ILAT register bit is set when an interrupt rising edge is detected (detection requires two core clock cycles). The bit is cleared when the respective IPEND register bit is set. The IPEND bit indicates that the event has entered into the processor pipeline. At this point the CEC will recognize and queue the next rising edge event on the corresponding event input. The minimum latency from the rising edge transition of the generalpurpose interrupt to the IPEND output asserted is three core clock cycles; however, the latency can be much higher, depending on the activity within and the state of the processor. DMA CONTROLLERS The ADSP-BF534 processor has multiple, independent DMA controllers that support automated data transfers with minimal overhead for the processor core. DMA transfers can occur between the ADSP-BF534 processor's internal memories and any of its DMA-capable peripherals. Additionally, DMA transfers can be accomplished between any of the DMA-capable peripherals and external devices connected to the external memory interfaces, including the SDRAM controller and the asynchronous memory controller. DMA-capable peripherals include the SPORTs, SPI port, UARTs, and PPI. Each individual DMA-capable peripheral has at least one dedicated DMA channel. The ADSP-BF534 processor DMA controller supports both 1dimensional (1D) and 2-dimensional (2D) DMA transfers. DMA transfer initialization can be implemented from registers or from sets of parameters called descriptor blocks. The 2D 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 deinterleaved on the fly. * 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 provided for transfers between the various memories of the ADSP-BF534 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 controlled by a very flexible descriptor-based methodology or by a standard register-based autobuffer mechanism. The ADSP-BF534 processor also includes an external DMA controller capability via dual external DMA request pins when used in conjunction 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 communications peripherals such as USB 2.0. It allows control of the number of data transfers for memDMA. The number of transfers per edge is programmable. This feature can be programmed to allow memDMA to have an increased priority on the external bus relative to the core. REAL-TIME CLOCK (RTC) The ADSP-BF534 processor 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 ADSP-BF534 processor. The RTC peripheral has dedicated power supply pins so that it can remain powered up and clocked even when the rest of the processor is in a lowpower state. The RTC provides several programmable 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. 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. * A single, linear buffer that stops upon completion Like the other peripherals, the RTC can wake up the ADSPBF534 processor from Sleep mode upon generation of any RTC wakeup event. Additionally, an RTC wakeup event can wake up the ADSP-BF534 processor from Deep Sleep mode, and wake up the on-chip internal voltage regulator from the Hibernate operating mode. * A circular, auto-refreshing buffer that interrupts on each full or fractionally full buffer Connect RTC pins RTXI and RTXO with external components as shown in Figure 4. Examples of DMA types supported by the ADSP-BF534 processor DMA controller include: Rev. PrD | Page 8 of 60 | January 2005 Preliminary Technical Data RTXI ADSP-BF534 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. RTXO R1 X1 C1 SERIAL PORTS (SPORTS) C2 The ADSP-BF534 processor incorporates two dual-channel synchronous serial ports (SPORT0 and SPORT1) for serial and multiprocessor communications. The SPORTs support the following features: SUGGESTED COMPONENTS: ECLIPTEK EC38J (THROUGH-HOLE PACKAGE) EPSON MC405 12 PF LOAD (SURFACE MOUNT PACKAGE) C1 = 22 PF C2 = 22 PF R1 = 10 M * I2S capable operation. * Bidirectional operation - Each SPORT has two sets of independent transmit and receive pins, enabling eight channels of I2S stereo audio. NOTE: C1 AND C2 ARE SPECIFIC TO CRYSTAL SPECIFIED FOR X1. CONTACT CRYSTAL MANUFACTURER FOR DETAILS. C1 AND C2 SPECIFICATIONS ASSUME BOARD TRACE CAPACITANCE OF 3 PF. * Buffered (8-deep) transmit and receive ports - Each port has a data register for transferring data words to and from other processor components and shift registers for shifting data in and out of the data registers. Figure 4. External Components for RTC WATCHDOG TIMER * Clocking - Each transmit and receive port can either use an external serial clock or generate its own, in frequencies ranging from (fSCLK/131,070) Hz to (fSCLK/2) Hz. The ADSP-BF534 processor includes a 32-bit timer that can be used to implement a software watchdog function. A software watchdog can improve system availability by forcing the processor to a known state through generation of a hardware reset, non-maskable interrupt (NMI), or general-purpose interrupt, if the timer expires before being reset by software. The programmer 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 remaining in an unknown state where software, which would normally reset the timer, has stopped running due to an external noise condition or software error. * Word length - Each SPORT supports serial data words from 3 to 32 bits in length, transferred most-significant-bit first or least-significant-bit first. * Framing - Each transmit and receive port can run with or without frame sync signals for each data word. Frame sync signals can be generated internally or externally, active high or low, and with either of two pulsewidths and early or late frame sync. * Companding in hardware - Each SPORT can perform A-law or -law companding according to ITU recommendation G.711. Companding can be selected on the transmit and/or receive channel of the SPORT without additional latencies. If configured to generate a hardware reset, the watchdog timer resets both the core and the ADSP-BF534 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. * DMA operations with single-cycle overhead - Each SPORT can automatically receive and transmit multiple buffers of memory data. The processor can link or chain sequences of DMA transfers between a SPORT and memory. The timer is clocked by the system clock (SCLK), at a maximum frequency of fSCLK. * Interrupts - Each transmit and receive port generates an interrupt upon completing the transfer of a data word or after transferring an entire data buffer or buffers through DMA. TIMERS There are nine general-purpose programmable timer units in the ADSP-BF534 processor. Eight timers have an external pin 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 pins, an external clock input to the PPI_CLK input pin, or to the internal SCLK. The timer units can be used in conjunction with the two UARTs and the CAN controller 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 providing periodic events for synchronization, either to the system clock or to a count of external signals. Rev. PrD | * Multichannel capability - Each SPORT supports 128 channels out of a 1024-channel window and is compatible with the H.100, H.110, MVIP-90, and HMVIP standards. SERIAL PERIPHERAL INTERFACE (SPI) PORT The ADSP-BF534 processor has an SPI-compatible port that enables the processor to communicate with multiple SPI-compatible devices. The SPI interface uses three pins for transferring data: two data pins (Master Output-Slave Input, MOSI, and Master InputSlave Output, MISO) and a clock pin (Serial Clock, SCK). An SPI chip select input pin (SPISS) lets other SPI devices select the Page 9 of 60 | January 2005 ADSP-BF534 Preliminary Technical Data processor, and seven SPI chip select output pins (SPISEL7-1) let the processor select other SPI devices. The SPI select pins are reconfigured Programmable Flag pins. Using these pins, the SPI port provides a full-duplex, synchronous serial interface, which supports both master/slave modes and multimaster environments. The SPI port's baud rate and clock phase/polarities are programmable, and it has an integrated DMA controller, configurable to support transmit or receive data streams. The SPI's DMA controller can only service unidirectional accesses at any given time. The SPI port's clock rate is calculated as: f SCLK SPI Clock Rate = --------------------------------2 x SPI_Baud Where the 16-bit SPI_Baud register contains a value of 2 to 65,535. During transfers, the SPI port simultaneously transmits and receives by serially shifting data in and out on its two serial data lines. The serial clock line synchronizes the shifting and sampling of data on the two serial data lines. Where the 16-bit UART_Divisor comes from the DLH register (most significant 8 bits) and DLL register (least significant 8 bits). In conjunction with the general-purpose timer functions, autobaud detection is supported. The capabilities of the UARTs are further extended with support for the Infrared Data Association (IrDA(R)) Serial Infrared Physical Layer Link Specification (SIR) protocol. CONTROLLER AREA NETWORK (CAN) The ADSP-BF534 processor offers a CAN controller that is a communication controller implementing the Controller Area Network (CAN) 2.0B (active) protocol. This protocol is an asynchronous communications protocol used in both industrial and automotive control systems. The CAN protocol is well suited for control applications due to its capability to communicate reliably over a network since the protocol incorporates CRC checking message error tracking, and fault node confinement. The ADSP-BF534 CAN controller offers the following features: * 32 mailboxes (8 receive only, 8 transmit only, 16 configurable for receive or transmit). * Dedicated acceptance masks for each mailbox. UART PORTS (UARTS) * Additional data filtering on first two bytes. The ADSP-BF534 processor provides 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, supporting full-duplex, DMA-supported, asynchronous transfers of serial data. A UART port includes support for 5 to 8 data bits, 1 or 2 stop bits, and none, even, or odd parity. Each UART port supports two modes of operation: * PIO (Programmed I/O) - The processor sends or receives data by writing or reading I/O-mapped UART registers. The data is double-buffered on both transmit and receive. * DMA (Direct Memory Access) - The DMA controller transfers both transmit and receive data. This reduces the number and frequency of interrupts required to transfer data to and from memory. The UART has two dedicated DMA channels, one for transmit and one for receive. These DMA channels have lower default priority than most DMA channels because of their relatively low service rates. Each UART port's baud rate, serial data format, error code generation and status, and interrupts are programmable: * Supporting bit rates ranging from (fSCLK/ 1,048,576) to (fSCLK/16) bits per second. * Supporting data formats from 7 to12 bits per frame. * Both transmit and receive operations can be configured to generate maskable interrupts to the processor. The UART port's clock rate is calculated as: f SCLK UART Clock Rate = -----------------------------------------------16 x UART_Divisor Rev. PrD | * Support for both the standard (11-bit) and extended (29bit) identifier (ID) message formats. * Support for remote frames. * Active or passive network support. * CAN wakeup from Hibernation Mode (lowest static power consumption mode). * Interrupts, including: TX Complete, RX Complete, Error, Global. The electrical characteristics of each network connection are very demanding so the CAN interface is typically divided into two parts: a controller and a transceiver. This allows a single controller to support different drivers and CAN networks. The ADSP-BF534 CAN module represents only the controller part of the interface. The controller interface supports connection to 3.3V high-speed, fault-tolerant, single-wire transceivers. TWI CONTROLLER INTERFACE The ADSP-BF534 processor includes a Two Wire Interface (TWI) module for providing a simple exchange method of control data between multiple devices. The TWI is compatible with the widely used I2C bus standard. The TWI module offers the capabilities of simultaneous Master and Slave operation, support for both 7-bit addressing and multimedia data arbitration. The TWI interface utilizes two pins for transferring clock (SCL) and data (SDA) and supports the protocol at speeds up to 400k bits/sec. The TWI interface pins are compatible with 5 V logic levels. Additionally, the ADSP-BF534 processor's TWI module is fully compatible with Serial Camera Control Bus (SCCB) functionality for easier control of various CMOS camera sensor devices. Page 10 of 60 | January 2005 Preliminary Technical Data ADSP-BF534 PORTS Because of the rich set of peripherals, the ADSP-BF534 processor groups the many peripheral signals to four ports--Port F, Port G, Port H, and Port J. Most of the associated pins are shared by multiple signals. The ports function as multiplexer controls. Eight of the pins (Port F7-0) offer high source/high sink current capabilities. and other general-purpose peripherals. The PPI consists of a dedicated input clock pin, up to 3 frame synchronization pins, and up to 16 data pins. 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: General-Purpose I/O (GPIO) * 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. The ADSP-BF534 processor has 48 bi-directional, general-purpose I/O (GPIO) pins allocated across three separate GPIO modules--PORTFIO, PORTGIO, and PORTHIO, associated with Port F, Port G, and Port H, respectively. Port J does not provide GPIO functionality. Each GPIO-capable pin shares functionality with other ADSP-BF534 processor peripherals via a multiplexing scheme; however, the GPIO functionality is the default state of the device upon power-up. Neither GPIO output or input drivers are active by default. Each general-purpose port pin can be individually controlled by manipulation of the port control, status, and interrupt registers: * Vertical Blanking Only Mode--The PPI only transfers Vertical 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 preamble sequences, and ancillary data that may be embedded in horizontal and vertical blanking intervals. * GPIO Direction Control Register - Specifies the direction of each individual GPIO pin as input or output. * GPIO Control and Status Registers - The ADSP-BF534 processor employs a "write one to modify" mechanism that allows any combination of individual GPIO pins to be modified in a single instruction, without affecting the level of any other GPIO pins. Four control registers are provided. One register is written in order to set pin values, one register is written in order to clear pin values, one register is written in order to toggle pin values, and one register is written in order to specify a pin value. Reading the GPIO status register allows software to interrogate the sense of the pins. * GPIO Interrupt Mask Registers - The two GPIO Interrupt Mask registers allow each individual GPIO pin to function as an interrupt to the processor. Similar to the two GPIO Control Registers that are used to set and clear individual pin values, one GPIO Interrupt Mask Register sets bits to enable interrupt function, and the other GPIO Interrupt Mask register clears bits to disable interrupt function. GPIO pins defined as inputs can be configured to generate hardware interrupts, while output pins can be triggered by software interrupts. * GPIO Interrupt Sensitivity Registers - The two GPIO Interrupt Sensitivity Registers specify whether individual pins are level- or edge-sensitive and specify--if edge-sensitive--whether just the rising edge or both the rising and falling edges of the signal are significant. One register selects the type of sensitivity, and one register selects which edges are significant for edge-sensitivity. PARALLEL PERIPHERAL INTERFACE (PPI) The ADSP-BF534 processor provides a Parallel Peripheral Interface (PPI) that can connect directly to parallel A/D and D/A converters, ITU-R-601/656 video encoders and decoders, Rev. PrD | Though not explicitly supported, ITU-R-656 output functionality 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 2D 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 assertion of a frame sync and reception/transmission of data. DYNAMIC POWER MANAGEMENT The ADSP-BF534 processor provides five 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. Control of clocking to each of the ADSP-BF534 processor peripherals also reduces power consumption. See Table 4 for a summary of the power settings for each mode. Page 11 of 60 | January 2005 ADSP-BF534 Preliminary Technical Data 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 performance 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. 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. The hibernate mode maximizes static power savings by disabling the voltage and clocks to the processor core (CCLK) and to all the synchronous peripherals (SCLK). The internal voltage regulator for the processor can be shut off by writing b#00 to the FREQ bits of the VR_CTL register. This disables both CCLK and SCLK. Furthermore, it sets the internal power supply voltage (VDDINT) to 0V to provide the greatest power savings mode. Any critical information stored internally (memory contents, register contents, etc.) must be written to a non-volatile storage device prior to removing power if the processor state is to be preserved. System Clock (SCLK) Core Power Since VDDEXT is still supplied in this mode, all of the external pins tri-state, unless otherwise specified. This allows other devices that may be connected to the processor to have power still applied without drawing unwanted current. Core Clock (CCLK) Sleep Deep Sleep Hibernate Enabled Enabled/ Disabled Enabled Disabled Disabled Hibernate Operating Mode - Maximum Static Power Savings PLL Bypassed Full On Active PLL Mode Table 4. Power Settings rupt causes the processor to transition to the Active mode. Assertion of RESET while in Deep Sleep mode causes the processor to transition to the Full On mode. The internal supply regulator can be woken up by CAN. It can also be woken up by a Real-Time Clock wakeup event or by asserting the RESET pin, both of which initiate the hardware reset sequence. No Yes Enabled Enabled Enabled Enabled On On Power Savings - Disabled Disabled Disabled Enabled Disabled Disabled On On Off 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. Typically an external event or RTC activity will wake up the processor. When in the Sleep mode, assertion of wakeup will cause the processor to sense the value of the BYPASS bit in the PLL Control register (PLL_CTL). If BYPASS is disabled, the processor will transition to the Full On mode. If BYPASS is enabled, the processor will transition to the Active mode. When in the Sleep mode, system DMA access to L1 memory is not supported. Deep Sleep Operating Mode - Maximum Dynamic Power Savings The Deep Sleep mode maximizes dynamic power savings by disabling the clocks to the processor core (CCLK) and to all synchronous peripherals (SCLK). Asynchronous peripherals, such as the RTC, may still be running but will not be able to 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 inter- Rev. PrD | As shown in Table 5, the ADSP-BF534 processor supports three different power domains. The use of multiple power domains maximizes flexibility, while maintaining compliance with industry standards and conventions. By isolating the internal logic of the ADSP-BF534 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. Table 5. Power Domains Power Domain All internal logic, except RTC RTC internal logic and crystal I/O All other I/O VDD Range VDDINT VDDRTC VDDEXT The power dissipated by a processor is largely a function of the clock frequency of the processor and the square of the operating voltage. For example, reducing the clock frequency by 25% results in a 25% reduction in power dissipation, while reducing the voltage by 25% reduces 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. The Dynamic Power Management feature of the ADSP-BF534 processor allows both the processor's input voltage (VDDINT) and clock frequency (fCCLK) to be dynamically controlled. Page 12 of 60 | January 2005 Preliminary Technical Data ADSP-BF534 CLOCK SIGNALS As explained above, the savings in power dissipation can be modeled by the following equations: The ADSP-BF534 processor can be clocked by an external crystal, a sine wave input, or a buffered, shaped clock derived from an external clock oscillator. Power Savings Factor If an external clock is used, it should be a TTL compatible signal and must not be halted, changed, or operated below the specified frequency during normal operation. This signal is connected to the processor's CLKIN pin. When an external clock is used, the XTAL pin must be left unconnected. 2 T f CCLKRED V DDINTRED RED = -------------------------------- x -------------------------------------- x ------------------ f CCLKNOM V T NOM DDINTNOM % Power Savings = ( 1 - Power Savings Factor ) x 100% Alternatively, because the ADSP-BF534 processor includes an on-chip oscillator circuit, an external crystal may be used. The crystal should be connected across the CLKIN and XTAL pins, with two capacitors connected as shown in Figure 6. Capacitor values are dependent on crystal type and should be specified by the crystal manufacturer. A parallel-resonant, fundamental frequency, microprocessor-grade crystal should be used. where the variables in the equations are: * fCCLKNOM is the nominal core clock frequency * fCCLKRED is the reduced core clock frequency * VDDINTNOM is the nominal internal supply voltage * VDDINTRED is the reduced internal supply voltage * TNOM is the duration running at fCCLKNOM * TRED is the duration running at fCCLKRED CLKIN VOLTAGE REGULATION XTAL CLKOUT CLKBUF The ADSP-BF534 processor provides an on-chip voltage regulator that can generate processor core voltage levels (0.85V to 1.2V guaranteed from -5% to 10%) from an external 2.25 V to 3.6 V supply. Figure 5 shows the typical external components required to complete the power management system. The regulator controls the internal logic voltage levels and is programmable with the Voltage Regulator Control Register (VR_CTL) in increments of 50 mV. To reduce standby power consumption, the internal voltage regulator can be programmed to remove power to the processor core while keeping I/O power supplied. While in Hibernate mode, VDDEXT can still be applied, eliminating the need for external buffers. The voltage regulator can be activated from this power down state by assertion of the RESET pin, which will then initiate a boot sequence. The regulator can also be disabled and bypassed at the user's discretion.

PROCESSOR Figure 6. External Crystal Connections The CLKBUF pin is an output pin, and is a buffer version of the input clock. The Blackfin core is running at a different clock rate than the on-chip peripherals. As shown in Figure 7 on page 14, 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 user programmable 1x to 63x multiplication factor (bounded by specified minimum and maximum VCO frequencies). The default multiplier is 10x, but it can be modified by a software instruction sequence. On-the-fly frequency changes can be effected by simply writing to the PLL_DIV register. On-the-fly CCLK and SCLK frequency changes can be effected by simply writing to the PLL_DIV register. Whereas the maximum allowed CCLK and SCLK rates depend on the applied voltages VDDINT and VDDEXT, the VCO is always permitted to run up to the frequency specified by the part's speed grade. The CLKOUT pin reflects the SCLK frequency to the off-chip world. It belongs to the SDRAM interface, but it functions as reference signal in other timing specifications as well. While active by default, it can be disabled by 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 Figure 5. Voltage Regulator Circuit Rev.

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 7. 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 60), it also depends on the applied VDDINT voltage. See Table 10 - Table 11 for details. The maximal system clock rate (SCLK) depends on the chip package and the applied VDDEXT voltage (see Table 13). Table 7.

PrD | Description Execute from 16-bit external memory (Bypass Boot ROM) Boot from 8-bit or 16-bit memory (EPROM/flash) Reserved Boot from serial SPI memory (EEPROM/flash) Boot from SPI host (slave mode) Boot from serial TWI memory (EEPROM/flash) Boot from TWI host (slave mode) Boot from UART host (slave mode) * Execute from 16-bit external memory - Execution starts from address 0x2000 0000 with 16-bit packing. The boot ROM is bypassed in this mode. All configuration settings are set for the slowest device possible (3-cycle hold time; 15-cycle R/W access times; 4-cycle setup). * Boot from 8-bit and 16-bit external flash memory - The 8-bit or 16-bit flash boot routine located in boot ROM memory space is set up using Asynchronous Memory Bank 0. All configuration settings are set for the slowest device possible (3-cycle hold time; 15-cycle R/W access times; 4-cycle setup). The boot ROM evaluates the first byte of the boot stream at address 0x2000 0000. If it is 0x40, 8-bit boot is performed. A 0x60 byte is required for 16-bit boot. * Boot from serial SPI memory (EEPROM or flash). Eight-, 16-, or 24-bit addressable devices are supported as well as AT45DB041, AT45DB081, and AT45DB161 data flash devices from Atmel. The SPI uses the PF10/SPI SSEL1 output pin to select a single SPI EEPROM/flash device, submits a read command and successive address bytes (0x00) until a valid 8-, 16-, or 24-bit, or Atmel addressable device is detected, and begins clocking data into the processor. * Boot from SPI host device - The Blackfin processor operates in SPI slave mode and is configured to receive the bytes of the .LDR file from an SPI host (master) agent. To hold off the host device from transmitting while the boot ROM is busy, the Blackfin processor will assert a flag pin to signal the host device not to send any more bytes until the flag is de-asserted. The flag is chosen by the user and this information will be transferred to the Blackfin processor via bits 8:5 of the FLAG header. Page 14 of 60 | January 2005 Preliminary Technical Data ADSP-BF534 * Boot from UART - Using an autobaud handshake sequence, a boot-stream-formatted program is downloaded by the Host. The Host agent selects a baud rate within the UART's clocking capabilities. When performing the autobaud, the UART expects a "@" (boot stream) character (eight bits data, one start bit, one stop bit, no parity bit) on the RXD pin to determine the bit rate. It then replies with an acknowledgement which is composed of 4 bytes: 0xBF, the value of UART_DLL, the value of UART_DLH, 0x00. The Host can then download the boot stream. When the processor needs to hold off the Host, it de-asserts CTS. Therefore, the Host must monitor this signal. supports both user (algorithm/application code) and supervisor (O/S kernel, device drivers, debuggers, ISRs) modes of operation, allowing multiple levels of access to core processor resources. * Boot from serial TWI memory (EEPROM/flash) - The Blackfin processor operates in master mode and selects the TWI slave with the unique id 0xA0. It submits successive read commands to the memory device starting at two byte internal address 0x0000 and begins clocking data into the processor. The TWI memory device should comply with Philips I2C Bus Specification version 2.1 and have the capability to auto-increment its internal address counter such that the contents of the memory device can be read sequentially. * All registers, I/O, and memory are mapped into a unified 4G byte memory space, providing a simplified programming model. * Boot from TWI Host - The TWI Host agent selects the slave with the unique id 0x5F. The processor replies with an acknowledgement and the Host can then download the boot stream. The TWI Host agent should comply with Philips I2C Bus Specification version 2.1. An I2C multiplexer can be used to select one processor at a time when booting multiple processors from a single TWI. For each of the boot modes, a 10-byte header is first brought in from an external 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 start of L1 instruction SRAM. In addition, bit 4 of the Reset Configuration Register can be set by application code to bypass the normal boot sequence during a software reset. For this case, the processor jumps directly to the beginning of L1 instruction memory. To augment the boot modes, a secondary software loader can be added to provide additional booting mechanisms. This secondary loader could provide the capability to boot from flash, variable baud rate, and other sources. In all boot modes except Bypass, program execution starts from on-chip L1 memory address 0xFFA0 0000. The assembly language, which takes advantage of the processor'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 MAC or four 8-bit ALU + two load/store + two pointer updates per cycle. * 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- and 32-bit instructions (no mode switching, no code segregation). Frequently used instructions are encoded in 16 bits. DEVELOPMENT TOOLS The ADSP-BF534 processor is supported with a complete set of CROSSCORE(R) software and hardware development tools, including Analog Devices emulators and VisualDSP++(R) development environment. The same emulator hardware that supports other Blackfin processors also fully emulates the ADSP-BF534 processor. DESIGNING AN EMULATOR-COMPATIBLE PROCESSOR BOARD (TARGET) The Analog Devices family of emulators are tools that every system developer needs to test and debug hardware and software systems. Analog Devices has supplied an IEEE 1149.1 JTAG Test Access Port (TAP) on each JTAG processor. The emulator uses the TAP to access the internal features of the processor, allowing the developer to load code, set breakpoints, observe variables, observe memory, and examine registers. The processor must be halted to send data and commands, but once an operation has been completed by the emulator, the processor system is set running at full speed with no impact on system timing. To use these emulators, the target board must include a header that connects the processor's JTAG port to the emulator. 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 provide 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 programmer 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 compiling C and C++ source code. In addition, the architecture Rev.

PrD | Page 16 of 60 | January 2005 Preliminary Technical Data ADSP-BF534 PIN DESCRIPTIONS ADSP-BF534 processor pin definitions are listed in Table 9. In order to maintain maximum functionality and reduce package size and pin count, some pins have dual, multiplexed functionality. In cases where pin functionality is reconfigurable, the default state is shown in plain text, while alternate functionality is shown in italics. Pins shown with an asterisk after their name (*) offer high source/high sink current capabilities. All pins are tristated during and immediately after reset with the exception of the external memory interface. On the external memory interface, the control and address lines are driven high during reset unless the BR pin is asserted. All I/O pins have their input buffers disabled with the exception of the pins noted in the data sheet that need pullups or pulldowns if unused. Table 9.

Voltage regulator output is guaranteed from -5% to 10% of specified values. 3 The ADSP-BF534 processor is 3.3 V tolerant (always accepts up to 3.6 V maximum VIH), but voltage compliance (on outputs, VOH) depends on the input VDDEXT, because VOH (maximum) approximately equals VDDEXT (maximum). This 3.3 V tolerance applies to bi-directional pins (DATA15-0, PF15-0, PG15-0, PH15-0, TFS0, TCLK0, RSCLK0, RFS0) and input only pins (BR, ARDY, DR0PRI, DR0SEC, RTXI, TCK, TDI, TMS, TRST, CLKIN, RESET, NMI, and BMODE2-0). 4 Parameter value applies to all input and bi-directional pins except CLKIN, SDA, and SCL. 5 Parameter value applies to CLKIN pin only. 6 Certain ADSP-BF534 processor pins are 5.0 V tolerant (always accept up to 5.5 V maximum VIH), but voltage compliance (on outputs, VOH) depends on the input VDDEXT, because VOH (maximum) approximately equals VDDEXT (maximum). This 5.0 V tolerance applies to SDA and SCL pins only. The SDA and SCL pins are open drain and therefore require a pullup resistor. Consult the I2C specification version 2.1 for the proper resistor value. 7 Parameter value applies to all input and bi-directional pins except SDA and SCL. 2 Rev.

These are stress ratings only. Functional operation of the device at these or any other conditions 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. 2 For proper SDRAM controller operation, the maximum load capacitance is 50 pF (at 3.3V) or 30 pF (at 2.5V) for ADDR19-1, DATA15-0, ABE1-0/SDQM1-0, CLKOUT, SCKE, SA10, SRAS, SCAS, SWE, and SMS. Figure 8. Product Information on Package ESD SENSITIVITY CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADSP-BF534 processor features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Rev.

PrD | Page 48 of 60 | January 2005 Preliminary Technical Data ADSP-BF534 POWER DISSIPATION Total power dissipation has two components: one due to internal circuitry (PINT) and one due to the switching of external output drivers (PEXT). Table 40 shows the power dissipation for internal circuitry (VDDINT). Internal power dissipation is dependent on the instruction execution sequence and the data operands involved. The external component of total power dissipation is caused by the switching of output pins. Its magnitude depends on: * Maximum frequency (f0) at which all output pins can switch during each cycle * Load capacitance (C0) of all switching output pins * Their voltage swing (VDDEXT) The external component is calculated using: IDDTYP2 IDDEFR3 IDDSLEEP45 IDDDEEPSLEEP4 IDDHIBERNATE5 Parameter IDDTYP2 IDDEFR3 IDDSLEEP45 IDDDEEPSLEEP4 IDDHIBERNATE5 fCCLK = 250 MHz VDDINT = 1.0 V TBD TBD TBD TBD 50 fCCLK = 400 MHz VDDINT = 1.0 V TBD TBD TBD TBD 50 P TOTAL = P EXT + ( I DD x V DDINT ) Note that the conditions causing a worst-case PEXT differ from those causing a worst-case PINT . Maximum PINT cannot occur while 100% of the output pins are switching from all ones (1s) to all zeros (0s). Note, as well, that it is not common for an application to have 100% or even 50% of the outputs switching simultaneously. All timing parameters appearing in this data sheet were measured under the conditions described in this section. Output Enable Time Table 40. Internal Power Dissipation Parameter A typical power consumption can now be calculated for these conditions by adding a typical internal power dissipation: TEST CONDITIONS 2 P EXT = V DDEXT x C 0 f 0 Test Conditions1 fCCLK = fCCLK = 50 MHz 150 MHz VDDINT = VDDINT = 0.8 V 0.9 V TBD TBD TBD TBD TBD TBD TBD TBD 50 50 fCCLK = 200 MHz VDDINT = 0.9 V TBD TBD TBD TBD 50 The frequency f includes driving the load high and then back low. For example: DATA15-0 pins can drive high and low at a maximum rate of 1/(2 tSCLK) while in SDRAM burst mode. fCCLK = 400 MHz VDDINT = 1.2 V TBD TBD TBD TBD 50 fCCLK = 500 MHz VDDINT = 1.2 V TBD TBD TBD TBD 50 Unit mA mA mA mA A Unit Output pins 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 tENA 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 in the Output Enable/Disable diagram (Figure 39). The time tENA_MEASURED is the interval from when the reference signal switches to when the output voltage reaches 2.0 V (output high) or 1.0 V (output low). Time tTRIP is the interval from when the output starts driving to when the output reaches the 1.0 V or 2.0 V trip voltage. Time tENA is calculated as shown in the equation: t ENA = t ENA_MEASURED - t TRIP mA mA mA mA A If multiple pins (such as the data bus) are enabled, the measurement value is that of the first pin to start driving. 1 IDD data is specified for typical process parameters.

PrD | Page 49 of 60 | January 2005 ADSP-BF534 Preliminary Technical Data Output Disable Time Example System Hold Time Calculation Output pins 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 time for the voltage on the bus to decay by V is dependent on the capacitive load, CL and the load current, IL. This decay time can be approximated by the equation: To determine the data output hold time in a particular system, first calculate tDECAY using the equation given above. Choose V to be the difference between the ADSP-BF534 processor's output voltage and the input threshold for the device requiring the hold time. A typical V will be 0.4 V. CL is the total bus capacitance (per data line), and IL is the total leakage or three-state current (per data line). The hold time will be tDECAY plus the minimum disable time (for example, tDSDAT for an SDRAM write cycle). t DECAY = ( C L V ) I L The output disable time tDIS is the difference between tDIS_MEASURED and tDECAY as shown in Figure 39. The time tDIS_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. The time tDECAY is calculated with test loads CL and IL, and with V equal to 0.5 V. tDIS_MEASURED VOL (MEASURED) VOH (MEASURED) V VOH 2.0V (MEASURED) VOL (MEASURED) + V 1.0V tDECAY OUTPUT STOPS DRIVING 30pF tENA-MEASURED tENA VOH (MEASURED) 1.5V Figure 40.
