Key to Pin Definitions
•Ctrl.: The output signal for a port pin is selected by bit field PC in the associated
register Px_IOCRy. Output O0 is selected by setting the respective bit field PC to
1x00B, output O1 is selected by 1x01B, etc.
Output signal OH is controlled by hardware.
•Type: Indicates the pad type and its power supply domain (A, B, M, 1).
– St: Standard pad
– Sp: Special pad e.g. XTALx
– DP: Double pad - can be used as standard or high speed pad
– In: Input only pad
– PS: Power supply pad

3 Functional Description
The architecture of the XC236xB combines advantages of RISC, CISC, and DSP
processors with an advanced peripheral subsystem in a well-balanced design. On-chip
memory blocks allow the design of compact systems-on-silicon with maximum
performance suited for computing, control, and communication.
The on-chip memory blocks (program code memory and SRAM, dual-port RAM, data
SRAM) and the generic peripherals are connected to the CPU by separate high-speed
buses. Another bus, the LXBus, connects additional on-chip resources and external
resources (see Figure 4). This bus structure enhances overall system performance by
enabling the concurrent operation of several subsystems of the XC236xB.
The block diagram gives an overview of the on-chip components and the advanced
internal bus structure of the XC236xB.

Functional Description
Data Sheet 41 V1.1, 2009-07
This common memory space consists of 16 Mbytes organized as 256 segments of
64 Kbytes; each segment contains four data pages of 16 Kbytes. The entire memory
space can be accessed bytewise or wordwise. Portions of the on-chip DPRAM and the
register spaces (ESFR/SFR) additionally are directly bit addressable.
The internal data memory areas and the Special Function Register areas (SFR and
ESFR) are mapped into segment 0, the system segment.
The Program Management Unit (PMU) handles all code fetches and, therefore, controls
access to the program memories such as Flash memory and PSRAM.
The Data Management Unit (DMU) handles all data transfers and, therefore, controls
access to the DSRAM and the on-chip peripherals.
Both units (PMU and DMU) are connected to the high-speed system bus so that they can
exchange data. This is required if operands are read from program memory, code or
data is written to the PSRAM, code is fetched from external memory, or data is read from
or written to external resources. These include peripherals on the LXBus such as USIC
or MultiCAN. The system bus allows concurrent two-way communication for maximum
transfer performance.
Up to 16 Kbytes of on-chip Program SRAM (PSRAM) are provided to store user code
or data. The PSRAM is accessed via the PMU and is optimized for code fetches. A
section of the PSRAM with programmable size can be write-protected.
Note: The actual size of the PSRAM depends on the quoted device type.
Reserved for DSRAM 00’8000H00’9FFFH8 Kbytes
External memory area 00’0000H00’7FFFH32 Kbytes
1) Accesses to the shaded areas are reserved. In devices with external bus interface these accesses generate
external bus accesses.
2) The areas marked with “<” are slightly smaller than indicated, see column “Notes”.
3) The uppermost 4-Kbyte sector of the first Flash segment is reserved for internal use (C0’F000H to C0’FFFFH).

Up to 16 Kbytes of on-chip Data SRAM (DSRAM) are used for storage of general user
data. The DSRAM is accessed via a separate interface and is optimized for data access.
Note: The actual size of the DSRAM depends on the quoted device type.
2 Kbytes of on-chip Dual-Port RAM (DPRAM) provide storage for user-defined
variables, for the system stack, and for general purpose register banks. A register bank
can consist of up to 16 word-wide (R0 to R15) and/or byte-wide (RL0, RH0, …, RL7,
RH7) General Purpose Registers (GPRs).
The upper 256 bytes of the DPRAM are directly bit addressable. When used by a GPR,
any location in the DPRAM is bit addressable.
8 Kbytes of on-chip Stand-By SRAM (SBRAM) provide storage for system-relevant
user data that must be preserved while the major part of the device is powered down.
The SBRAM is accessed via a specific interface and is powered in domain M.
1024 bytes (2 × 512 bytes) of the address space are reserved for the Special Function
Register areas (SFR space and ESFR space). SFRs are word-wide registers which are
used to control and monitor functions of the different on-chip units. Unused SFR
addresses are reserved for future members of the XC2000 Family. In order to ensure
upward compatibility they should either not be accessed or written with zeros.
In order to meet the requirements of designs where more memory is required than is
available on chip, up to 12 Mbytes (approximately, see Table 8) of external RAM and/or
ROM can be connected to the microcontroller. The External Bus Interface also provides
access to external peripherals.
The on-chip Flash memory stores code, constant data, and control data. The
320 Kbytes of on-chip Flash memory consist of 1 module of 64 Kbytes (preferably for
data storage) and 1 module of 256 Kbytes. Each module is organized in 4-Kbyte sectors.
The uppermost 4-Kbyte sector of segment 0 (located in Flash module 0) is used
internally to store operation control parameters and protection information.
Note: The actual size of the Flash memory depends on the chosen device type.
Each sector can be separately write protected1), erased and programmed (in blocks of
128 Bytes). The complete Flash area can be read-protected. A user-defined password
sequence temporarily unlocks protected areas. The Flash modules combine 128-bit
read access with protected and efficient writing algorithms for programming and erasing.
Dynamic error correction provides extremely high read data security for all read access
operations. Access to different Flash modules can be executed in parallel.
For Flash parameters, please see Section 4.6.
1) To save control bits, sectors are clustered for protection purposes, they remain separate for
programming/erasing.

Memory Content Protection
The contents of on-chip memories can be protected against soft errors (induced e.g. by
radiation) by activating the parity mechanism or the Error Correction Code (ECC).
The parity mechanism can detect a single-bit error and prevent the software from using
incorrect data or executing incorrect instructions.
The ECC mechanism can detect and automatically correct single-bit errors. This
supports the stable operation of the system.
It is strongly recommended to activate the ECC mechanism wherever possible because
this dramatically increases the robustness of an application against such soft errors.

3.2 External Bus Controller
All external memory access operations are performed by a special on-chip External Bus
Controller (EBC). The EBC also controls access to resources connected to the on-chip
LXBus (MultiCAN and the USIC modules). The LXBus is an internal representation of
the external bus that allows access to integrated peripherals and modules in the same
way as to external components.
The EBC can be programmed either to Single Chip Mode, when no external memory is
required, or to an external bus mode with the following selections1):
• Address Bus Width with a range of 0 … 24-bit
• Data Bus Width 8-bit or 16-bit
• Bus Operation Multiplexed or Demultiplexed
The bus interface uses Port 10 and Port 2 for addresses and data. In the demultiplexed
bus modes, the lower addresses are output separately on Port 0 and Port 1. The number
of active segment address lines is selectable, restricting the external address space to
8 Mbytes … 64 Kbytes. This is required when interface lines shall be assigned to Port 2.
External CS signals (address windows plus default) can be generated and output on
Port 4 in order to save external glue logic. External modules can be directly connected
to the common address/data bus and their individual select lines.
Important timing characteristics of the external bus interface are programmable (with
registers TCONCSx/FCONCSx) to allow the user to adapt it to a wide range of different
types of memories and external peripherals.
Access to very slow memories or modules with varying access times is supported by a
special ‘Ready’ function. The active level of the control input signal is selectable.
In addition, up to four independent address windows may be defined (using registers
ADDRSELx) to control access to resources with different bus characteristics. These
address windows are arranged hierarchically where window 4 overrides window 3, and
window 2 overrides window 1. All accesses to locations not covered by these four
address windows are controlled by TCONCS0/FCONCS0. The currently active window
can generate a chip select signal.
The external bus timing is based on the rising edge of the reference clock output
CLKOUT. The external bus protocol is compatible with that of the standard C166 Family.
1) Bus modes are switched dynamically if several address windows with different mode settings are used.

3.3 Central Processing Unit (CPU)
The core of the CPU consists of a 5-stage execution pipeline with a 2-stage instruction-
fetch pipeline, a 16-bit arithmetic and logic unit (ALU), a 32-bit/40-bit multiply and
accumulate unit (MAC), a register-file providing three register banks, and dedicated

Data Sheet 46 V1.1, 2009-07
With this hardware most XC236xB instructions are executed in a single machine cycle
of 12.5 ns @ 80-MHz CPU clock. For example, shift and rotate instructions are always
processed during one machine cycle, no matter how many bits are shifted. Also,
multiplication and most MAC instructions execute in one cycle. All multiple-cycle
instructions have been optimized so that they can be executed very fast; for example, a
32-/16-bit division is started within 4 cycles while the remaining cycles are executed in
the background. Another pipeline optimization, the branch target prediction, eliminates
the execution time of branch instructions if the prediction was correct.
The CPU has a register context consisting of up to three register banks with 16 word-
wide GPRs each at its disposal. One of these register banks is physically allocated within
the on-chip DPRAM area. A Context Pointer (CP) register determines the base address
of the active register bank accessed by the CPU at any time. The number of these
register bank copies is only restricted by the available internal RAM space. For easy
parameter passing, a register bank may overlap others.
A system stack of up to 32 Kwords is provided for storage of temporary data. The system
stack can be allocated to any location within the address space (preferably in the on-chip
RAM area); it is accessed by the CPU with the stack pointer (SP) register. Two separate
SFRs, STKOV and STKUN, are implicitly compared with the stack pointer value during
each stack access to detect stack overflow or underflow.
The high performance of the CPU hardware implementation can be best utilized by the
programmer with the highly efficient XC236xB instruction set. This includes the following
instruction classes:
• Standard Arithmetic Instructions
• DSP-Oriented Arithmetic Instructions
• Logical Instructions
• Boolean Bit Manipulation Instructions
• Compare and Loop Control Instructions
• Shift and Rotate Instructions
• Prioritize Instruction
• Data Movement Instructions
• System Stack Instructions
• Jump and Call Instructions
• Return Instructions
• System Control Instructions
• Miscellaneous Instructions
The basic instruction length is either 2 or 4 bytes. Possible operand types are bits, bytes
and words. A variety of direct, indirect or immediate addressing modes are provided to
specify the required operands.

3.4 Memory Protection Unit (MPU)
The XC236xB’s Memory Protection Unit (MPU) protects user-specified memory areas
from unauthorized read, write, or instruction fetch accesses. The MPU can protect the
whole address space including the peripheral area. This completes established
mechanisms such as the register security mechanism or stack overrun/underrun
detection.
Four Protection Levels support flexible system programming where operating system,
low level drivers, and applications run on separate levels. Each protection level permits
different access restrictions for instructions and/or data.
Every access is checked (if the MPU is enabled) and an access violating the permission
rules will be marked as invalid and leads to a protection trap.
A set of protection registers for each protection level specifies the address ranges and
the access permissions. Applications requiring more than 4 protection levels can
dynamically re-program the protection registers.
3.5 Memory Checker Module (MCHK)
The XC236xB’s Memory Checker Module calculates a checksum (fractional polynomial
division) on a block of data, often called Cyclic Redundancy Code (CRC). It is based on
a 32-bit linear feedback shift register and may, therefore, also be used to generate
pseudo-random numbers.
The Memory Checker Module is a 16-bit parallel input signature compression circuitry
which enables error detection within a block of data stored in memory, registers, or
communicated e.g. via serial communication lines. It reduces the probability of error
masking due to repeated error patterns by calculating the signature of blocks of data.
The polynomial used for operation is configurable, so most of the commonly used
polynomials may be used. Also, the block size for generating a CRC result is
configurable via a local counter. An interrupt may be generated if testing the current data
block reveals an error.
An autonomous CRC compare circuitry is included to enable redundant error detection,
e.g. to enable higher safety integrity levels.
The Memory Checker Module provides enhanced fault detection (beyond parity or ECC)
for data and instructions in volatile and non volatile memories. This is especially
important for the safety and reliability of embedded systems.

Functional Description
Data Sheet 48 V1.1, 2009-07
3.6 Interrupt System
The architecture of the XC236xB supports several mechanisms for fast and flexible
response to service requests; these can be generated from various sources internal or
external to the microcontroller. Any of these interrupt requests can be programmed to be
serviced by the Interrupt Controller or by the Peripheral Event Controller (PEC).
Using a standard interrupt service the current program execution is suspended and a
branch to the interrupt vector table is performed. With the PEC just one cycle is ‘stolen’
from the current CPU activity to perform the PEC service. A PEC service implies a single
byte or word data transfer between any two memory locations with an additional
increment of either the PEC source pointer, the destination pointer, or both. An individual
PEC transfer counter is implicitly decremented for each PEC service except when
performing in the continuous transfer mode. When this counter reaches zero, a standard
interrupt is performed to the corresponding source-related vector location. PEC services
are particularly well suited to supporting the transmission or reception of blocks of data.
The XC236xB has eight PEC channels, each with fast interrupt-driven data transfer
capabilities.
With a minimum interrupt response time of 7/111) CPU clocks, the XC236xB can react
quickly to the occurrence of non-deterministic events.
Interrupt Nodes and Source Selection
The interrupt system provides 96 physical nodes with separate control register
containing an interrupt request flag, an interrupt enable flag and an interrupt priority bit
field. Most interrupt sources are assigned to a dedicated node. A particular subset of
interrupt sources shares a set of nodes. The source selection can be programmed using
the interrupt source selection (ISSR) registers.
External Request Unit (ERU)
A dedicated External Request Unit (ERU) is provided to route and preprocess selected
on-chip peripheral and external interrupt requests. The ERU features 4 programmable
input channels with event trigger logic (ETL) a routing matrix and 4 output gating units
(OGU). The ETL features rising edge, falling edge, or both edges event detection. The
OGU combines the detected interrupt events and provides filtering capabilities
depending on a programmable pattern match or miss.
Trap Processing
The XC236xB provides efficient mechanisms to identify and process exceptions or error
conditions that arise during run-time, the so-called ‘Hardware Traps’. A hardware trap
causes an immediate system reaction similar to a standard interrupt service (branching
1) Depending if the jump cache is used or not.

to a dedicated vector table location). The occurrence of a hardware trap is also indicated
by a single bit in the trap flag register (TFR). Unless another higher-priority trap service
is in progress, a hardware trap will interrupt any ongoing program execution. In turn,
hardware trap services can normally not be interrupted by standard or PEC interrupts.
Depending on the package option up to 3 External Service Request (ESR) pins are
provided. The ESR unit processes their input values and allows to implement user
controlled trap functions (System Requests SR0 and SR1). In this way reset, wakeup
and power control can be efficiently realized.
Software interrupts are supported by the ‘TRAP’ instruction in combination with an
individual trap (interrupt) number. Alternatively to emulate an interrupt by software a
program can trigger interrupt requests by writing the Interrupt Request (IR) bit of an
interrupt control register.
3.7 On-Chip Debug Support (OCDS)
The On-Chip Debug Support system built into the XC236xB provides a broad range of
debug and emulation features. User software running on the XC236xB can be debugged
within the target system environment.
The OCDS is controlled by an external debugging device via the debug interface. This
either consists of the 2-pin Device Access Port (DAP) or of the JTAG port conforming to
IEEE-1149. The debug interface can be completed with an optional break interface.
The debugger controls the OCDS with a set of dedicated registers accessible via the
debug interface (DAP or JTAG). In addition the OCDS system can be controlled by the
CPU, e.g. by a monitor program. An injection interface allows the execution of OCDS-
generated instructions by the CPU.
Multiple breakpoints can be triggered by on-chip hardware, by software, or by an
external trigger input. Single stepping is supported, as is the injection of arbitrary
instructions and read/write access to the complete internal address space. A breakpoint
trigger can be answered with a CPU halt, a monitor call, a data transfer, or/and the
activation of an external signal.
Tracing of data can be obtained via the debug interface, or via the external bus interface
for increased performance.
Tracing of program execution is supported by the XC2000 Family emulation device. With
this device the DAP can operate on clock rates of up to 20 MHz.
The DAP interface uses two interface signals, the JTAG interface uses four interface
signals, to communicate with external circuitry. The debug interface can be amended
with two optional break lines.

3.8 Capture/Compare Unit (CC2)
The CAPCOM unit supports generation and control of timing sequences on up to
16 channels with a maximum resolution of one system clock cycle (eight cycles in
staggered mode). The CAPCOM unit is typically used to handle high-speed I/O tasks
such as pulse and waveform generation, pulse width modulation (PWM), digital to
analog (D/A) conversion, software timing, or time recording with respect to external
events.
Two 16-bit timers with reload registers provide two independent time bases for the
capture/compare register array.
The input clock for the timers is programmable to several prescaled values of the internal
system clock, or may be derived from an overflow/underflow of timer T6 in module GPT2.
This provides a wide range of variation for the timer period and resolution and allows
precise adjustments to the application specific requirements. In addition, external count
inputs allow event scheduling for the capture/compare registers relative to external
events.
The capture/compare register array contains 16 dual purpose capture/compare
registers, each of which may be individually allocated to either CAPCOM timer and
programmed for capture or compare function.
All registers have each one port pin associated with it which serves as an input pin for
triggering the capture function, or as an output pin to indicate the occurrence of a
compare event.
When a capture/compare register has been selected for capture mode, the current
contents of the allocated timer will be latched (‘captured’) into the capture/compare
register in response to an external event at the port pin which is associated with this
register. In addition, a specific interrupt request for this capture/compare register is
generated. Either a positive, a negative, or both a positive and a negative external signal
transition at the pin can be selected as the triggering event.
The contents of all registers which have been selected for one of the five compare modes
are continuously compared with the contents of the allocated timers.
When a match occurs between the timer value and the value in a capture/compare
register, specific actions will be taken based on the selected compare mode.

3.9 Capture/Compare Units CCU6x
The XC236xB types feature several CCU6 units (CCU60, CCU61).
The CCU6 is a high-resolution capture and compare unit with application-specific
modes. It provides inputs to start the timers synchronously, an important feature in
devices with several CCU6 modules.
The module provides two independent timers (T12, T13), that can be used for PWM
generation, especially for AC motor control. Additionally, special control modes for block
commutation and multi-phase machines are supported.

3.10 General Purpose Timer (GPT12E) Unit
The GPT12E unit is a very flexible multifunctional timer/counter structure which can be
used for many different timing tasks such as event timing and counting, pulse width and
duty cycle measurements, pulse generation, or pulse multiplication.
The GPT12E unit incorporates five 16-bit timers organized in two separate modules,
GPT1 and GPT2. Each timer in each module may either operate independently in a
number of different modes or be concatenated with another timer of the same module.
Each of the three timers T2, T3, T4 of module GPT1 can be configured individually for
one of four basic modes of operation: Timer, Gated Timer, Counter, and Incremental
Interface Mode. In Timer Mode, the input clock for a timer is derived from the system
clock and divided by a programmable prescaler. Counter Mode allows timer clocking in
reference to external events.
Pulse width or duty cycle measurement is supported in Gated Timer Mode, where the
operation of a timer is controlled by the ‘gate’ level on an external input pin. For these
purposes each timer has one associated port pin (TxIN) which serves as a gate or clock
input. The maximum resolution of the timers in module GPT1 is 4 system clock cycles.
The counting direction (up/down) for each timer can be programmed by software or
altered dynamically by an external signal on a port pin (TxEUD), e.g. to facilitate position
tracking.
In Incremental Interface Mode the GPT1 timers can be directly connected to the
incremental position sensor signals A and B through their respective inputs TxIN and
TxEUD. Direction and counting signals are internally derived from these two input
signals, so that the contents of the respective timer Tx corresponds to the sensor
position. The third position sensor signal TOP0 can be connected to an interrupt input.
Timer T3 has an output toggle latch (T3OTL) which changes its state on each timer
overflow/underflow. The state of this latch may be output on pin T3OUT e.g. for time out
monitoring of external hardware components. It may also be used internally to clock
timers T2 and T4 for measuring long time periods with high resolution.
In addition to the basic operating modes, T2 and T4 may be configured as reload or
capture register for timer T3. A timer used as capture or reload register is stopped. The
contents of timer T3 is captured into T2 or T4 in response to a signal at the associated
input pin (TxIN). Timer T3 is reloaded with the contents of T2 or T4, triggered either by
an external signal or a selectable state transition of its toggle latch T3OTL. When both
T2 and T4 are configured to alternately reload T3 on opposite state transitions of T3OTL
with the low and high times of a PWM signal, this signal can be continuously generated
without software intervention.

Data Sheet 57 V1.1, 2009-07
With its maximum resolution of 2 system clock cycles, the GPT2 module provides
precise event control and time measurement. It includes two timers (T5, T6) and a
capture/reload register (CAPREL). Both timers can be clocked with an input clock which
is derived from the CPU clock via a programmable prescaler or with external signals. The
counting direction (up/down) for each timer can be programmed by software or altered
dynamically with an external signal on a port pin (TxEUD1)). Concatenation of the timers
is supported with the output toggle latch (T6OTL) of timer T6, which changes its state on
each timer overflow/underflow.
The state of this latch may be used to clock timer T5, and/or it may be output on pin
T6OUT. The overflows/underflows of timer T6 can also be used to clock the CAPCOM2
timers and to initiate a reload from the CAPREL register.
The CAPREL register can capture the contents of timer T5 based on an external signal
transition on the corresponding port pin (CAPIN); timer T5 may optionally be cleared
after the capture procedure. This allows the XC236xB to measure absolute time
differences or to perform pulse multiplication without software overhead.
The capture trigger (timer T5 to CAPREL) can also be generated upon transitions of

3.11 Real Time Clock
The Real Time Clock (RTC) module of the XC236xB can be clocked with a clock signal
selected from internal sources or external sources (pins).
The RTC basically consists of a chain of divider blocks:
• Selectable 32:1 and 8:1 dividers (on - off)
• The reloadable 16-bit timer T14
• The 32-bit RTC timer block (accessible via registers RTCH and RTCL) consisting of:
– a reloadable 10-bit timer
– a reloadable 6-bit timer
– a reloadable 6-bit timer
– a reloadable 10-bit timer
All timers count up. Each timer can generate an interrupt request. All requests are
combined to a common node request.

3.12 A/D Converters
For analog signal measurement, up to two 10-bit A/D converters (ADC0, ADC1) with
11 + 5 multiplexed input channels and a sample and hold circuit have been integrated
on-chip. 4 inputs can be converted by both A/D converters. Conversions use the
successive approximation method. The sample time (to charge the capacitors) and the
conversion time are programmable so that they can be adjusted to the external circuit.
The A/D converters can also operate in 8-bit conversion mode, further reducing the
conversion time.
Several independent conversion result registers, selectable interrupt requests, and
highly flexible conversion sequences provide a high degree of programmability to meet
the application requirements. Both modules can be synchronized to allow parallel
sampling of two input channels.
For applications that require more analog input channels, external analog multiplexers
can be controlled automatically. For applications that require fewer analog input
channels, the remaining channel inputs can be used as digital input port pins.
The A/D converters of the XC236xB support two types of request sources which can be
triggered by several internal and external events.
• Parallel requests are activated at the same time and then executed in a predefined
sequence.
• Queued requests are executed in a user-defined sequence.
In addition, the conversion of a specific channel can be inserted into a running sequence
without disturbing that sequence. All requests are arbitrated according to the priority
level assigned to them.
Data reduction features reduce the number of required CPU access operations allowing
the precise evaluation of analog inputs (high conversion rate) even at a low CPU speed.
Result data can be reduced by limit checking or accumulation of results.
The Peripheral Event Controller (PEC) can be used to control the A/D converters or to
automatically store conversion results to a table in memory for later evaluation, without
requiring the overhead of entering and exiting interrupt routines for each data transfer.
Each A/D converter contains eight result registers which can be concatenated to build a
result FIFO. Wait-for-read mode can be enabled for each result register to prevent the
loss of conversion data.
In order to decouple analog inputs from digital noise and to avoid input trigger noise,
those pins used for analog input can be disconnected from the digital input stages. This
can be selected for each pin separately with the Port x Digital Input Disable registers.
The Auto-Power-Down feature of the A/D converters minimizes the power consumption
when no conversion is in progress.
Broken wire detection for each channel and a multiplexer test mode provide information
to verify the proper operation of the analog signal sources (e.g. a sensor system).

3.13 Universal Serial Interface Channel Modules (USIC)
The XC236xB features the USIC modules USIC0, USIC1, USIC2. Each module provides
two serial communication channels.
The Universal Serial Interface Channel (USIC) module is based on a generic data shift
and data storage structure which is identical for all supported serial communication
protocols. Each channel supports complete full-duplex operation with a basic data buffer
structure (one transmit buffer and two receive buffer stages). In addition, the data
handling software can use FIFOs.
The protocol part (generation of shift clock/data/control signals) is independent of the
general part and is handled by protocol-specific preprocessors (PPPs).
The USIC’s input/output lines are connected to pins by a pin routing unit. The inputs and
outputs of each USIC channel can be assigned to different interface pins, providing great
flexibility to the application software. All assignments can be made during runtime.
Figure 11 General Structure of a USIC Module
The regular structure of the USIC module brings the following advantages:
• Higher flexibility through configuration with same look-and-feel for data management
• Reduced complexity for low-level drivers serving different protocols
• Wide range of protocols with improved performances (baud rate, buffer handling)

Target Protocols
Each USIC channel can receive and transmit data frames with a selectable data word
width from 1 to 16 bits in each of the following protocols:
•UART (asynchronous serial channel)
– module capability: maximum baud rate = fSYS / 4
– data frame length programmable from 1 to 63 bits
– MSB or LSB first
•LIN Support (Local Interconnect Network)
– module capability: maximum baud rate = fSYS / 16
– checksum generation under software control
– baud rate detection possible by built-in capture event of baud rate generator
•SSC/SPI/QSPI (synchronous serial channel with or without data buffer)
– module capability: maximum baud rate = fSYS / 2, limited by loop delay
– number of data bits programmable from 1 to 63, more with explicit stop condition
– MSB or LSB first
– optional control of slave select signals
•IIC (Inter-IC Bus)
– supports baud rates of 100 kbit/s and 400 kbit/s
•IIS (Inter-IC Sound Bus)
– module capability: maximum baud rate = fSYS / 2
Note: Depending on the selected functions (such as digital filters, input synchronization
stages, sample point adjustment, etc.), the maximum achievable baud rate can be
limited. Please note that there may be additional delays, such as internal or
external propagation delays and driver delays (e.g. for collision detection in UART
mode, for IIC, etc.).

3.14 MultiCAN Module
The MultiCAN module contains independently operating CAN nodes with Full-CAN
functionality which are able to exchange Data and Remote Frames using a gateway
function. Transmission and reception of CAN frames is handled in accordance with CAN
specification V2.0 B (active). Each CAN node can receive and transmit standard frames
with 11-bit identifiers as well as extended frames with 29-bit identifiers.
All CAN nodes share a common set of message objects. Each message object can be
individually allocated to one of the CAN nodes. Besides serving as a storage container
for incoming and outgoing frames, message objects can be combined to build gateways
between the CAN nodes or to set up a FIFO buffer.
Note: The number of CAN nodes and message objects depends on the selected device
type.
The message objects are organized in double-chained linked lists, where each CAN
node has its own list of message objects. A CAN node stores frames only into message
objects that are allocated to its own message object list and it transmits only messages
belonging to this message object list. A powerful, command-driven list controller
performs all message object list operations.

3.15 System Timer
The System Timer consists of a programmable prescaler and two concatenated timers
(10 bits and 6 bits). Both timers can generate interrupt requests. The clock source can
be selected and the timers can also run during power reduction modes.
Therefore, the System Timer enables the software to maintain the current time for
scheduling functions or for the implementation of a clock.
3.16 Watchdog Timer
The Watchdog Timer is one of the fail-safe mechanisms which have been implemented
to prevent the controller from malfunctioning for longer periods of time.
The Watchdog Timer is always enabled after an application reset of the chip. It can be
disabled and enabled at any time by executing the instructions DISWDT and ENWDT
respectively. The software has to service the Watchdog Timer before it overflows. If this
is not the case because of a hardware or software failure, the Watchdog Timer
overflows, generating a prewarning interrupt and then a reset request.
The Watchdog Timer is a 16-bit timer clocked with the system clock divided by 16,384
or 256. The Watchdog Timer register is set to a prespecified reload value (stored in
WDTREL) in order to allow further variation of the monitored time interval. Each time it
is serviced by the application software, the Watchdog Timer is reloaded and the
prescaler is cleared.
Time intervals between 3.2 μs and 13.4 s can be monitored (@ 80 MHz).
The default Watchdog Timer interval after power-up is 6.5 ms (@ 10 MHz).

3.17 Clock Generation
The Clock Generation Unit can generate the system clock signal fSYS for the XC236xB
from a number of external or internal clock sources:
• External clock signals with pad voltage or core voltage levels
• External crystal or resonator using the on-chip oscillator
• On-chip clock source for operation without crystal/resonator
• Wake-up clock (ultra-low-power) to further reduce power consumption
The programmable on-chip PLL with multiple prescalers generates a clock signal for
maximum system performance from standard crystals, a clock input signal, or from the
on-chip clock source. See also Section 4.7.2.
The Oscillator Watchdog (OWD) generates an interrupt if the crystal oscillator frequency
falls below a certain limit or stops completely. In this case, the system can be supplied
with an emergency clock to enable operation even after an external clock failure.
All available clock signals can be output on one of two selectable pins.

3.18 Parallel Ports
The XC236xB provides up to 76 I/O lines which are organized into 7 input/output ports
and 2 input ports. All port lines are bit-addressable, and all input/output lines can be
individually (bit-wise) configured via port control registers. This configuration selects the
direction (input/output), push/pull or open-drain operation, activation of pull devices, and
edge characteristics (shape) and driver characteristics (output current) of the port
drivers. The I/O ports are true bidirectional ports which are switched to high impedance
state when configured as inputs. During the internal reset, all port pins are configured as
inputs without pull devices active.
All port lines have alternate input or output functions associated with them. These
alternate functions can be programmed to be assigned to various port pins to support the
best utilization for a given application. For this reason, certain functions appear several
times in Table 10.
All port lines that are not used for alternate functions may be used as general purpose
I/O lines.

4 Electrical Parameters
The operating range for the XC236xB is defined by its electrical parameters. For proper
operation the specified limits must be respected when integrating the device in its target
environment.
4.1 General Parameters
These parameters are valid for all subsequent descriptions, unless otherwise noted.
Note: Stresses above the values listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. This is a stress rating only. Functional operation
of the device at these or any other conditions above those indicated in the
operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for an extended time may affect device reliability.
During absolute maximum rating overload conditions (VIN > VDDP or VIN < VSS) the
voltage on VDDP pins with respect to ground (VSS) must not exceed the values
defined by the absolute maximum ratings.

1) To ensure the stability of the voltage regulators the EVRs must be buffered with ceramic capacitors. Separate
buffer capacitors with the recomended values shall be connected as close as possible to each VDDI pin to keep
the resistance of the board tracks below 2 Ohm. Connect all VDDI1 pins together. The minimum capacitance
value is required for proper operation under all conditions (e.g. temperature). Higher values slightly increase
the startup time.
2) Use one Capacitor for each pin.
3) This is the reference load. For bigger capacitive loads, use the derating factors listed in the PAD properties
section.
4) The timing is valid for pin drivers operating in default current mode (selected after reset). Reducing the output
current may lead to increased delays or reduced driving capability (CL).
5) The operating frequency range may be reduced for specific device types. This is indicated in the device
designation (...FxxL). 80 MHz devices are marked ...F80L.
6) Overload conditions occur if the standard operating conditions are exceeded, i.e. the voltage on any pin
exceeds the specified range: VOV > VIHmax (IOV > 0) or VOV < VILmin ((IOV < 0). The absolute sum of input
overload currents on all pins may not exceed 50 mA. The supply voltages must remain within the specified
limits. Proper operation under overload conditions depends on the application. Overload conditions must not
occur on pin XTAL1 (powered by VDDI).
7) An overload current (IOV) through a pin injects a certain error current (IINJ) into the adjacent pins. This error
current adds to the respective pins leakage current (IOZ). The amount of error current depends on the overload
current and is defined by the overload coupling factor KOV. The polarity of the injected error current is inverse
compared to the polarity of the overload current that produces it.The total current through a pin is |ITOT| = |IOZ|
+ (|IOV| KOV). The additional error current may distort the input voltage on analog inputs.

The XC236xB can operate within a wide supply voltage range from 3.0 V to 5.5 V.
However, during operation this supply voltage must remain within 10 percent of the
selected nominal supply voltage. It cannot vary across the full operating voltage range.
Because of the supply voltage restriction and because electrical behavior depends on
the supply voltage, the parameters are specified separately for the upper and the lower
voltage range.
During operation, the supply voltages may only change with a maximum speed of
dV/dt < 1 V/ms.
Leakage current is strongly dependent on the operating temperature and the voltage
level at the respective pin. The maximum values in the following tables apply under worst
case conditions, i.e. maximum temperature and an input level equal to the supply
voltage.
The value for the leakage current in an application can be determined by using the
respective leakage derating formula (see tables) with values from that application.
The pads of the XC236xB are designed to operate in various driver modes. The DC
parameter specifications refer to the pad current limits specified in Section 4.7.4.

Pullup/Pulldown Device Behavior
Most pins of the XC236xB feature pullup or pulldown devices. For some special pins
these are fixed; for the port pins they can be selected by the application.
The specified current values indicate how to load the respective pin depending on the
intended signal level. Figure 13 shows the current paths.
The shaded resistors shown in the figure may be required to compensate system pull
currents that do not match the given limit values.

1) Because each double bond pin is connected to two pads (standard pad and high-speed pad), it has twice the
normal value. For a list of affected pins refer to the pin definitions table in chapter 2.
2) Not subject to production test - verified by design/characterization. Hysteresis is implemented to avoid
metastable states and switching due to internal ground bounce. It cannot suppress switching due to external
system noise under all conditions.
3) If the input voltage exceeds the respective supply voltage due to ground bouncing (VIN < VSS) or supply ripple
(VIN > VDDP), a certain amount of current may flow through the protection diodes. This current adds to the
leakage current. An additional error current (IINJ) will flow if an overload current flows through an adjacent pin.
Please refer to the definition of the overload coupling factor KOV.
4) The given values are worst-case values. In production test, this leakage current is only tested at 125 °C; other

a temperature of 95 °C the resulting leakage current is 3.2 μA. Leakage derating depending on voltage level
(DV = VDDP - VPIN [V]): IOZ = IOZtempmax - (1.6 x DV) (μA]. This voltage derating formula is an approximation
which applies for maximum temperature.
5) Drive the indicated minimum current through this pin to change the default pin level driven by the enabled pull
device: VPIN <= VIL for a pullup; VPIN >= VIH for a pulldown.
6) These values apply to the fixed pull-devices in dedicated pins and to the user-selectable pull-devices in
general purpose IO pins.
7) Limit the current through this pin to the indicated value so that the enabled pull device can keep the default
pin level: VPIN >= VIH for a pullup; VPIN <= VIL for a pulldown.
8) The maximum deliverable output current of a port driver depends on the selected output driver mode. This
specification is not valid for outputs which are switched to open drain mode. In this case the respective output
will float and the voltage is determined by the external circuit.
9) As a rule, with decreasing output current the output levels approach the respective supply level (VOL->VSS,
VOH->VDDP). However, only the levels for nominal output currents are verified.

4.3.3 Power Consumption
The power consumed by the XC236xB depends on several factors such as supply
voltage, operating frequency, active circuits, and operating temperature. The power
consumption specified here consists of two components:
• The switching current IS depends on the device activity
• The leakage current ILK depends on the device temperature
To determine the actual power consumption, always both components, switching current
IS and leakage current ILK must be added:
IDDP = IS + ILK.
Note: The power consumption values are not subject to production test. They are
verified by design/characterization.
To determine the total power consumption for dimensioning the external power
supply, also the pad driver currents must be considered.
The given power consumption parameters and their values refer to specific operating
conditions:
•Active mode:
Regular operation, i.e. peripherals are active, code execution out of Flash.
•Stopover mode:
Crystal oscillator and PLL stopped, Flash switched off, clock in domain DMP_1
stopped.
Note: The maximum values cover the complete specified operating range of all
manufactured devices.
The typical values refer to average devices under typical conditions, such as
nominal supply voltage, room temperature, application-oriented activity.
After a power reset, the decoupling capacitors for VDDI are charged with the
maximum possible current.
For additional information, please refer to Section 5.2, Thermal Considerations.
Note: Operating Conditions apply.

Active Mode Power Supply Current
The actual power supply current in active mode not only depends on the system
frequency but also on the configuration of the XC236xB’s subsystem.
Besides the power consumed by the device logic the power supply pins also provide the
current that flows through the pin output drivers.
A small current is consumed because the drivers’ input stages are switched.
The IO power domains can be supplied separately. Power domain A (VDDPA) supplies the
A/D converters and Port 6. Power domain B (VDDPB) supplies the on-chip EVVRs and all
other ports.
During operation domain A draws a maximum current of 1.5 mA for each active A/D
converter module from VDDPA.
In Fast Startup Mode (with the Flash modules deactivated), the typical current is reduced
to 3 + 0.6×fSYS mA.

The XC236xB is delivered with all Flash sectors erased and with no protection installed.
The data retention time of the XC236xB’s Flash memory (i.e. the time after which stored
data can still be retrieved) depends on the number of times the Flash memory has been
erased and programmed.
Note: These parameters are not subject to production test but verified by design and/or

Access to the XC236xB Flash modules is controlled by the IMB. Built-in prefetch
mechanisms optimize the performance for sequential access.
Flash access waitstates only affect non-sequential access. Due to prefetch
mechanisms, the performance for sequential access (depending on the software
structure) is only partially influenced by waitstates.
1) The unused Flash module(s) can be erased/programmed while code is executed and/or data is read from only
one Flash module or from PSRAM. The Flash module that delivers code/data can, of course, not be
erased/programmed.
2) Flash module 1 can be erased/programmed while code is executed and/or data is read from Flash module 0.
3) Value of IMB_IMBCTRL.WSFLASH.
4) Programming and erase times depend on the internal Flash clock source. The control state machine needs a
few system clock cycles. This increases the stated durations noticably only at extremely low system clock
frequencies.
5) A maximum of 64 Flash sectors can be cycled 15,000 times. For all other sectors the limit is 1,000 cycles.

4.7.2 Definition of Internal Timing
The internal operation of the XC236xB is controlled by the internal system clock fSYS.
Because the system clock signal fSYS can be generated from a number of internal and
external sources using different mechanisms, the duration of the system clock periods
(TCSs) and their variation (as well as the derived external timing) depend on the
mechanism used to generate fSYS. This must be considered when calculating the timing
for the XC236xB.
Figure 19 Generation Mechanisms for the System Clock
Note: The example of PLL operation shown in Figure 19 uses a PLL factor of 1:4; the
example of prescaler operation uses a divider factor of 2:1.
The specification of the external timing (AC Characteristics) depends on the period of the
system clock (TCS).

Data Sheet 96 V1.1, 2009-07
Direct Drive
When direct drive operation is selected (SYSCON0.CLKSEL = 11B), the system clock is
derived directly from the input clock signal CLKIN1:
fSYS = fIN.
The frequency of fSYS is the same as the frequency of fIN. In this case the high and low
times of fSYS are determined by the duty cycle of the input clock fIN.
Selecting Bypass Operation from the XTAL11) input and using a divider factor of 1 results
in a similar configuration.
Prescaler Operation
When prescaler operation is selected (SYSCON0.CLKSEL = 10B, PLLCON0.VCOBY =
1B), the system clock is derived either from the crystal oscillator (input clock signal
XTAL1) or from the internal clock source through the output prescaler K1 (= K1DIV+1):
fSYS = fOSC / K1.
If a divider factor of 1 is selected, the frequency of fSYS equals the frequency of fOSC. In
this case the high and low times of fSYS are determined by the duty cycle of the input
clock fOSC (external or internal).
The lowest system clock frequency results from selecting the maximum value for the
divider factor K1:
fSYS = fOSC / 1024.
4.7.2.1 Phase Locked Loop (PLL)
When PLL operation is selected (SYSCON0.CLKSEL = 10B, PLLCON0.VCOBY = 0B),
the on-chip phase locked loop is enabled and provides the system clock. The PLL
multiplies the input frequency by the factor F (fSYS = fIN × F).
F is calculated from the input divider P (= PDIV+1), the multiplication factor N (=
NDIV+1), and the output divider K2 (= K2DIV+1):
(F = N / (P × K2)).
The input clock can be derived either from an external source at XTAL1 or from the on-
chip clock source.
The PLL circuit synchronizes the system clock to the input clock. This synchronization is
performed smoothly so that the system clock frequency does not change abruptly.
Adjustment to the input clock continuously changes the frequency of fSYS so that it is
locked to fIN. The slight variation causes a jitter of fSYS which in turn affects the duration
of individual TCSs.
1) Voltages on XTAL1 must comply to the core supply voltage VDDI1.

XC2000 Family / Value Line
Electrical Parameters
Data Sheet 97 V1.1, 2009-07
The timing in the AC Characteristics refers to TCSs. Timing must be calculated using the
minimum TCS possible under the given circumstances.
The actual minimum value for TCS depends on the jitter of the PLL. Because the PLL is
constantly adjusting its output frequency to correspond to the input frequency (from
crystal or oscillator), the accumulated jitter is limited. This means that the relative
deviation for periods of more than one TCS is lower than for a single TCS (see formulas
and Figure 20).
This is especially important for bus cycles using waitstates and for the operation of
timers, serial interfaces, etc. For all slower operations and longer periods (e.g. pulse train
generation or measurement, lower baudrates, etc.) the deviation caused by the PLL jitter
is negligible.
The value of the accumulated PLL jitter depends on the number of consecutive VCO
output cycles within the respective timeframe. The VCO output clock is divided by the
output prescaler K2 to generate the system clock signal fSYS. The number of VCO cycles
is K2 ×T, where T is the number of consecutive fSYS cycles (TCS).
The maximum accumulated jitter (long-term jitter) DTmax is defined by:
DTmax [ns] = ±(220 / (K2 × fSYS) + 4.3)
This maximum value is applicable, if either the number of clock cycles T > (fSYS / 1.2) or
the prescaler value K2 > 17.
In all other cases for a timeframe of T × TCS the accumulated jitter DT is determined by:
DT [ns] = DTmax × [(1 - 0.058 × K2) × (T - 1) / (0.83 × fSYS - 1) + 0.058 × K2]
fSYS in [MHz] in all formulas.
Example, for a period of 3 TCSs @ 33 MHz and K2 = 4:
Dmax = ±(220 / (4 × 33) + 4.3) = 5.97 ns (Not applicable directly in this case!)
D3 = 5.97 × [(1 - 0.058 × 4) × (3 - 1) / (0.83 × 33 - 1) + 0.058 × 4]
= 5.97 × [0.768 × 2 / 26.39 + 0.232]
= 1.7 ns
Example, for a period of 3 TCSs @ 33 MHz and K2 = 2:
Dmax = ±(220 / (2 × 33) + 4.3) = 7.63 ns (Not applicable directly in this case!)
D3 = 7.63 × [(1 - 0.058 × 2) × (3 - 1) / (0.83 × 33 - 1) + 0.058 × 2]
= 7.63 × [0.884 × 2 / 26.39 + 0.116]

Note: The specified PLL jitter values are valid if the capacitive load per pin does not

The maximum peak-to-peak noise on the pad supply voltage (measured between
VDDPB pin 100 and VSS pin 1) is limited to a peak-to-peak voltage of VPP = 50 mV.
This can be achieved by appropriate blocking of the supply voltage as close as
possible to the supply pins and using PCB supply and ground planes.

4.7.2.2 Wakeup Clock
When wakeup operation is selected (SYSCON0.CLKSEL = 00B), the system clock is
derived from the low-frequency wakeup clock source:
fSYS = fWU.
In this mode, a basic functionality can be maintained without requiring an external clock
source and while minimizing the power consumption.
4.7.2.3 Selecting and Changing the Operating Frequency
When selecting a clock source and the clock generation method, the required
parameters must be carefully written to the respective bit fields, to avoid unintended
intermediate states.
Many applications change the frequency of the system clock (fSYS) during operation in
order to optimize system performance and power consumption. Changing the operating
frequency also changes the switching currents, which influences the power supply.
To ensure proper operation of the on-chip EVRs while they generate the core voltage,
the operating frequency shall only be changed in certain steps. This prevents overshoots
and undershoots of the supply voltage.

4.7.3 External Clock Input Parameters
These parameters specify the external clock generation for the XC236xB. The clock can
be generated in two ways:
• By connecting a crystal or ceramic resonator to pins XTAL1/XTAL2.
• By supplying an external clock signal. This clock signal can be supplied either to
pin XTAL1 (core voltage domain) or to pin CLKIN1 (IO voltage domain).
If connected to CLKIN1, the input signal must reach the defined input levels VIL and VIH.
If connected to XTAL1, a minimum amplitude VAX1 (peak-to-peak voltage) is sufficient for
the operation of the on-chip oscillator.
Note: The given clock timing parameters (t1

4.7.4 Pad Properties
The output pad drivers of the XC236xB can operate in several user-selectable modes.
Strong driver mode allows controlling external components requiring higher currents
such as power bridges or LEDs. Reducing the driving power of an output pad reduces
electromagnetic emissions (EME). In strong driver mode, selecting a slower edge
reduces EME.
The dynamic behavior, i.e. the rise time and fall time, depends on the applied external
capacitance that must be charged and discharged. Timing values are given for a
capacitance of 20 pF, unless otherwise noted.
In general, the performance of a pad driver depends on the available supply voltage
VDDP. Therefore the following tables list the pad parameters for the upper voltage range
and the lower voltage range, respectively.
Note: These parameters are not subject to production test but verified by design and/or
characterization.

Variable Memory Cycles
External bus cycles of the XC236xB are executed in five consecutive cycle phases (AB,
C, D, E, F). The duration of each cycle phase is programmable (via the TCONCSx
registers) to adapt the external bus cycles to the respective external module (memory,
peripheral, etc.).
The duration of the access phase can optionally be controlled by the external module
using the READY handshake input.
This table provides a summary of the phases and the ranges for their length.
Note: The bandwidth of a parameter (from minimum to maximum value) covers the
whole operating range (temperature, voltage) as well as process variations. Within
a given device, however, this bandwidth is smaller than the specified range. This
is also due to interdependencies between certain parameters. Some of these
interdependencies are described in additional notes (see standard timing).

4.7.5.1 Bus Cycle Control with the READY Input
The duration of an external bus cycle can be controlled by the external circuit using the
READY input signal. The polarity of this input signal can be selected.
Synchronous READY permits the shortest possible bus cycle but requires the input
signal to be synchronous to the reference signal CLKOUT.
An asynchronous READY signal puts no timing constraints on the input signal but incurs
a minimum of one waitstate due to the additional synchronization stage. The minimum

duration of an asynchronous READY signal for safe synchronization is one CLKOUT
period plus the input setup time.
An active READY signal can be deactivated in response to the trailing (rising) edge of
the corresponding command (RD or WR).
If the next bus cycle is controlled by READY, an active READY signal must be disabled
before the first valid sample point in the next bus cycle. This sample point depends on
the programmed phases of the next cycle.

Package and Reliability
Data Sheet 124 V1.1, 2009-07
5 Package and Reliability
The XC2000 Family devices use the package type PG-LQFP (Plastic Green - Low
Profile Quad Flat Package). The following specifications must be regarded to ensure
proper integration of the XC236xB in its target environment.
5.1 Packaging
These parameters specify the packaging rather than the silicon.
Note: To improve the EMC behavior, it is recommended to connect the exposed pad to
the board ground, independent of the thermal requirements.
Board layout examples are given in an application note.
Package Compatibility Considerations
The XC236xB is a member of the XC2000 Family of microcontrollers. It is also
compatible to a certain extent with members of similar families or subfamilies.
Each package is optimized for the device it houses. Therefore, there may be slight
differences between packages of the same pin-count but for different device types. In
particular, the size of the Exposed Pad (if present) may vary.
If different device types are considered or planned for an application, it must be ensured
that the board layout fits all packages under consideration.

5.2 Thermal Considerations
When operating the XC236xB in a system, the total heat generated in the chip must be
dissipated to the ambient environment to prevent overheating and the resulting thermal
damage.
The maximum heat that can be dissipated depends on the package and its integration
into the target board. The “Thermal resistance RΘJA” quantifies these parameters. The
power dissipation must be limited so that the average junction temperature does not
exceed 150 °C.
The difference between junction temperature and ambient temperature is determined by
ΔT = (PINT + PIOSTAT + PIODYN) × RΘJA
The internal power consumption is defined as
PINT = VDDP × IDDP (switching current and leakage current).
The static external power consumption caused by the output drivers is defined as
PIOSTAT = Σ((VDDP-VOH) × IOH) + Σ(VOL × IOL)
The dynamic external power consumption caused by the output drivers (PIODYN) depends
on the capacitive load connected to the respective pins and their switching frequencies.
If the total power dissipation for a given system configuration exceeds the defined limit,
countermeasures must be taken to ensure proper system operation:
• Reduce VDDP, if possible in the system
• Reduce the system frequency
• Reduce the number of output pins
• Reduce the load on active output drivers
