1 TESTM IIn/BTestmode Enable
Enables factory test modes, must be held HIGH for
normal operation (connect to VDDPB).
An internal pullup device will hold this pin high
when nothing is driving it.
2TRST IIn/BTest-System Reset Input
For normal system operation, pin TRST should be
held low. A high level at this pin at the rising edge
of PORST activates the XC2723X’s debug
system. In this case, pin TRST must be driven low
once to reset the debug system.
An internal pulldown device will hold this pin low
when nothing is driving it.

3 Functional Description
The architecture of the XC2723X 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 3). This bus structure enhances overall system performance by
enabling the concurrent op eration of several subsystems of the XC2723X.
The block diagram gives an overview of the on-chip components and the advanced
internal bus structure of the XC2723X.

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. Po rti ons of the o n-chip DPR AM an d th e
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 inclu de peripheral s on the LXBus such as USIC
or MultiCAN. The system bus allows concurrent two-way communication for maximum
transfer performance.
4 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.

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 indicat ed, see column “Notes”.
3) The uppermost 4-Kbyte sector of the first Flash segment is reserved for int ernal use (C0’F000H to C0’FFFFH).
4) Several pipeline optimizations are not active within the external IO area.

6 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.
2 Kbytes of on-chip Dual-Port RAM (DPRAM) provide storage for user-defined
variables, for the system stack, and for genera l 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.
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.
The on-chip Flash memory stores code, constant data, and control data. The
160 Kbytes of on-chip Flash memory consist of 1 module of 32 Kbytes (preferably for
data storage) and 1 module of 128 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.
Each sector can be separately write protected1), erased and programmed (in blocks of
128 Bytes). The co mplete Flash area can be read-protected. A user-defined password
sequence temporarily unlocks protected areas. The Flash modules combine 128-bit
read access with pr otected and efficien t writing algorithms for pr ogramming 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.
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-bi t e rro r 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 agai nst such soft errors.
1) To save control bits, sectors are clustered for protection purposes, they remain separate for
programming/erasing.

XC2723X
XC2000 Family / Econo Lin e
Functional Des cription
Data Sheet 28 V1.1, 2011-09
With this hardware most XC2723X instru ctions are executed in a sing le 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 i s started within 4 cycles while the remaining cycle s are executed in
the background. Another pipel ine optimization, the branch target prediction, eliminates
the execution time of branch instructions if the prediction was correct.
The CPU has a register conte xt consisting of up to three register b anks 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 im plementation can be be st utilize d by the
programmer with the highly efficient XC2723X 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 ad dressing modes are provided to
specify the required operands.

3.3 Memory Protection Unit (MPU)
The XC2723X’s Memory Protection Unit (MPU) protects user-specified memory areas
from unauthorized read, write, or instruction fe tch 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 sp ecifies the address ranges and
the access permissions. Applications requiring more than 4 protection levels can
dynamically re-pro gra m th e pr otection register s.
3.4 Memory Checker Module (MCHK)
The XC2723X’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 Des cription
Data Sheet 30 V1.1, 2011-09
3.5 Interrupt System
The architecture of the XC2723X supports several mechanisms for fast and flexible
response to service requests; these can be generated from various sources internal or
external to the microcontroll er. 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 perfo rmed. Wi th th e PEC just one cycle is ‘stolen ’
from the current CPU activity to perform t he 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 XC2723X has eight PEC channels, each with fast interrupt-driven data transfer
capabilities.
With a minimum i nterrupt response time of 7/11 1) CPU clocks, the XC2723X can react
quickly to the occurrence of non-deterministic events.
Interrupt Nodes and Source Selection
The interrupt system provides 64 physical nodes with separate control register
containing an interrupt reque st flag, an interrupt enable flag and a n 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 l ogic (ETL) a routing matrix and 4 output ga ting units
(OGU). The ETL features rising ed ge, falling edg e, or both ed ges event detectio n. The
OGU combines the detected interrupt events and provides filtering capabilities
depending on a programmable pattern match or miss.
Trap Processing
The XC2723X 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.
XC2723X
XC2000 Family / Econo Lin e
Functional Des cription

to a dedicated vector table location). The occurrence of a hardware trap is also indicated
by a single bit in th e trap flag register (TFR ). Unl ess anoth er hig her-prior ity trap se rvice
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.
3.6 On-Chip Debug Support (OCDS)
The On-Chip Debug Supp ort system built into the XC27 23X provides a broad range of
debug and emulation features. User software running on the XC2723X can be debugged
within the target system environment.
The OCDS is controlled by an external debugging device via the debug interface. T his
consists of the 2-pin Device Access Port (DAP) or of th e 1-pin Single Pin DAP (SPD) 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 (SPD, DAP or JTAG). In ad dition 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.
The SPD interfa ce uses o ne interface sign al, DAP in terface u ses two in terface sig nals,
the JTAG interface uses four interface signals, to communicate with external circuitry.
The debug interface can be amended wi th two optional break lines.

3.7 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 General Purpose Timer (GPT12E) Unit
The GPT12E unit is a very flexible multif unctional timer/counter structu re which ca n be
used for many different timing tasks such as event timing and counting, pulse width and
duty cycle measurements, pulse generatio n, 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 programmab le prescale r. C ounter Mo de a llows timer clocki ng i n
reference to external events.
Pulse width or duty cycle measurement is supported in Gated Timer Mode, where the
operation of a timer is control led by the ‘gate’ level on an e xternal input pin. Fo r 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 T OP0 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. Th e
contents of timer T3 is captured into T2 or T 4 in response to a sign al at the associated
input pin (TxIN). Timer T3 is re loaded with th e contents of T2 or T4, trigge red either by
an external signal or a selectab le 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 con tinuously generated
without software intervention.
Note: Signals T2IN, T2EUD, T4EUD, T6OUT, T6IN and T6EUD are not connected to
pins.

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/dow n) for each timer can be programmed by software or altered
dynamically with an extern al signal on a port pin (TxEUD). Conc atenation 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 XC2723X 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
GPT1 timer T3 inputs T3IN and/or T3EUD. This is especially advantageous when T3
operates in Incremental Interface Mode.

3.10 Real Time Clock
The Real Time Clock (RTC) module of the XC2723X 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.

3.11 A/D Converters
For analog signal measurement, a 12-bit A/D converters (ADC0) with 10 multiplexed
input channels and a sample and hold circuit have been integrated on-chip. Conversions
use the successive approximation meth od. 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 and 10-bit conversion mode, further
reducing the conversion time.
Several independent conversion result registers, selectable interrupt requests, and
highly flexible conversion sequence s provid e a high deg ree of programmabi lity to meet
the application requirements.
For applications that require more analog input channels, external analog multiplexers
can be controlled automatically. For applications that require fewer analog input
channels, the remaini ng channel inputs can be used as digital input port pins.
The A/D converters of the XC2723X support two types of request sources which can be
triggered by several intern al and external events.
• Parallel requests are acti vated at the same time and then exe cuted 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. Two cascadable
filters build the hardware to generate a configurable moving average.
The Peripheral Event Controlle r (PEC) can be used to control the A/D con verters or to
automatically store conversion results to a table in memory for later evalua tion, without
requiring the overhead of entering and exiting interrupt routines for ea ch 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).

3.12 Universal Serial Interface Channel Modules (USIC)
The XC2723X features the USIC modules USIC0 and USIC1. Each module provides two
serial communication channels.
The Universal Serial Interface Ch annel (USI C) module is based on a g eneric 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 run time.
Figure 10 General Structure of a USIC Module
The regular structure of the USIC module brings the following advantag es:
• Higher flexibility through configuration with same look-and-feel for data management
• Reduced complexity for low-level dr ivers serving different protocols
• Wide range of protocols with improved performances (baud rate, buffer handling)

3.13 MultiCAN Module
The MultiCAN module contains two ind epen dently op erating CAN nodes with Ful l-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.
The two CAN nodes share a common set of message objects. Each message object can
be individually allocated to either 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.
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.

3.14 System Time r
The System Timer consists of a progra mmable prescaler and two concatenated timers
(10 bits and 6 bits). Both timers can generate in terrupt requests. Th e 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 implem entation of a clock.
3.15 Window Watchdog Timer
The Window 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 Window 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 Window Watchdog Timer before
it overflows. If this is not the case because of a hardware or software failure, the Window
Watchdog Timer overflows, generating a reset request.
The Window Watchdog Timer has a ‘programmable window boundary’, it disallows
refresh during the Window Watchdog Timer’s count-up. A refresh during this window-
boundary will cause the Window W atchdog Timer to also generate a reset request.
The Window Watchdog Timer is a 16-bit timer clocked with either the system clock or the
independent wake-up oscillator clock, divided by 16,384 or 256. The Window 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 Window Watchdog Timer is reloaded.

Data Sheet 48 V1.1, 2011-09
When clocked by fSYS = 80 MHz, time intervals between 12.5 ns and 13.4 s can be
monitored.
When clocked by fWU = 500 kHz, time intervals between 2.0 µs and 2147.5 s can be
monitored.
The default Watchdog Timer interval afte r power-up is 0.13 s (@ fWU = 500 kHz).
3.16 Clock Ge n era ti on
The Clock Generati on Unit can generate the system clock signal fSYS for the XC2723X
from a number of external or internal clock sou rce s:
• External clock signals with pad voltage or core volta ge 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 consumpti on
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 the EXTCL K pin.

3.17 Parallel Ports
The XC2723X provides u p to 33 I/O lin es which a re organized i nto 3 inp ut/output ports
and 1 input port. 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 appli cation. For thi s reason, certain functions app ear several
times in Table 10.
All port lines that are not used for alternate functions may be used as general purpose
I/O lines.

3.18 Power Management
The XC2723X provides the means to control the power it consumes either at a given time
or averaged over a certain duration.
Two mechanisms can be used (and partly in parallel):
•Clock Generation Management controls the frequency of internal and external
clock signals. Clock signals for currently inactive parts of logic are disabled
automatically. The user can drastically reduce the consumed power by reducing th e
XC2723X system clock frequency.
External circuits can be controlled using the programmable frequency output
EXTCLK.
•Peripheral Manageme nt permits temporary disabling of perip heral modules. Each
peripheral can be disabled and enabled separately. The CPU can be switched off
while the peripherals can continue to operate.
Wake-up from power reduction modes can be triggered either externally with signals
generated by the external system, or internally by the on-chip wake-up timer. This
supports intermittent operation of the XC2723X by generating cyclic wake-up signals.
Full performance is available to quickly react to action requests while the intermittent
sleep phases greatly reduce the average system powe r consumption.
Note: When selecting the suppl y voltage and the clock sou rce and generation meth od,
the required parameters must be carefully written to the respective bit fields, to
avoid unintended intermediate states. Recommended sequences are provided
which ensure the inte nded operation of power supply system and cloc k system.

4 Electrical Parameters
The operating range for the XC2723X 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 li sted under “Absolute Ma ximum 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 maximu m ratings.

1) To ensure the stability of t he voltage r egulators th e EVRs must be b uffered with cer amic capacitors. Separa te
buffer capacitors with the recomended values shall be connected as close as possible to each VDDIM pin to
keep the resistance of the board tracks below 2 Ohm. Connect all VDDIM pins together. The minimum
capacitance value is required for proper operation under all conditions (e.g. temperature). Higher values
slightly increase the startu p 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 curren t mode (se lected af ter reset) . Reducing the o utput
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). 66 MHz devices are marked ...F66L.
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.
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 lea kage current (IOZ). The amount of error current depends on the overload
current and is defined by the overlo ad coupl ing facto r KOV. The polarity of the in jected erro r curren t is inverse
compared to the pola rity of the overl oad current that pr oduces it.The t otal current through a pin is | ITOT| = |IOZ|
+ (|IOV| KOV). The additional error current may distort the input voltage on analog inputs.

4.2 Voltage Range definit ions
The XC2723X timing depends on the supply voltage. If such a dependency exists the
timing values are given for 2 voltage areas commonly used. The voltage areas are
defined in the following tables.
4.2.1 Parameter Interpretation
The parameters listed in the follo wing include both the characteristics of the XC272 3X
and its demands on the system. To aid in correctly interpreting the parameters when
evaluating them for a design, they are marked accordingly in the column “Symbol”:
CC (Controller Characteristics):
The logic of the XC2723X provides signals with the specified characteristics.
SR (System Requirement):
The external system must provide signals with the specified characteristics to the
XC2723X.

4.3 DC Parameters
These parameters are static or average values th at may be exceeded during switching
transitions (e.g. output current).
The XC2723X 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 parame ters are specified separately for the uppe r 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 XC2723X are designed to operate in various driver modes. The DC
parameter specifications refer to the pad current limits specifi ed in Section 4.7.4.

these are fixed; for the port pins they can be selected by the application.

1) 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.
2) If the input voltage exceeds the respecti ve supply vo ltage 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 erro r current (IINJ) will flow if an overload curre nt flows through an adjacent pin.
Please refer to the defini tion of the overload coupling factor KOV.
3) The given values are worst -case val ues. In production test , this l eakage current i s only tested at 125 °C; other
values are ensured by correlation. For derating, please refer to the following descriptions: Leakage derating
depending on temperature (TJ = junction temperature [°C]): IOZ = 0.05 x e(1.5 + 0.028 x TJ>) [μA]. For example, at
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.
4) Drive the indicated minimum current t hrough this pin to change the default pin leve l driven by the enable d pull
device.
5) Limit the current through this pin to the indicated value so that the enabled pull device can keep the default
pin level.
6) 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.
7) 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.
8) 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.

1) 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.
2) If the input voltage exceeds the respecti ve supply vo ltage 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 erro r current (IINJ) will flow if an overload curre nt flows through an adjacent pin.
Please refer to the defini tion of the overload coupling factor KOV.
3) The given values are worst -case val ues. In production test , this l eakage current i s only tested at 125 °C; other
values are ensured by correlation. For derating, please refer to the following descriptions: Leakage derating
depending on temperature (TJ = junction temperature [°C]): IOZ = 0.05 x e(1.5 + 0.028 x TJ>) [μA]. For example, at
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.
4) Drive the indicated minimum current t hrough this pin to change the default pin leve l driven by the enable d pull
device.
5) Limit the current through this pin to the indicated value so that the enabled pull device can keep the default
pin level.
6) 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.
7) 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.
8) As a rule, with decreasing output current the output levels approach the respective supply level (VOL->VSS,

4.3.3 Power Consumption
The power consumed by the XC2723X 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 ac tivity
• 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 con sidered.
The given power consumption parameters and their values refer to specific operating
conditions:
•Active mode:
Regular operation, i.e. periphe rals are active, code executio n out of Flash.
•Stopover mode:
Crystal oscillator and PLL stopped, Flash switched off, clock in most parts of domain
DMP_M 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 VDDIM 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 XC2723X’s subsystem.
Besides the power consumed by the device logic the power supply pins also provide the
current that flows through the pin outp ut drive r s.
A small current is consumed because the drivers’ input stages are switched.

measured under the following conditions:
Precondition: The pad supply is valid, i.e. VDDPB is above 3.0 V and remains above 3.0 V
even though the XC2723X is starting up. No debugger is attached.
Start condition: Power on reset is removed (PORST = 1).
End condition: External pin toggle caused by first user instruction executed from Flash

4.7.2 Definition of Internal Timing
The internal operation of the XC2723X is controlled by the internal system clock fSYS.
Because the system clock signal fSYS can be generated from a nu mber of internal and
external sources using different mech anisms, 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 XC2723X.
Figure 18 Generation Mechanisms for the System Clock
Note: The example of PLL operation shown in Figure 18 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).

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 freq uency of fIN. In this case the hi gh 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 throu gh the output prescaler K1 (= K1DIV+1):
fSYS = fOSC / K1.
If a divider factor of 1 is selected, the frequency of fSYS equals the freque ncy 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 sele cted (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 VDDIM.

Electrical Parameters
Data Sheet 83 V1.1, 2011-09
The timing in the AC Characteristics refers to TCSs. Timing must be calculated using the
minimum TCS possible under the give n 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 19).
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]
= 1.4 ns

Note: The specified PLL jitter values are valid if the capacitive load per pin does not
exceed CL=20pF.
The maximum peak-to-peak noise on the pad supply voltage (measured between
VDDPB pin and VSS pin) is limited to a peak-to-pea k 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 consump tion.
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 frequen cy of the system clock (fSYS) during operation in
order to optimize system performance and power consumption. Changing the operating
frequency also changes the switching curren ts, which influ ences the power supply.
To ensure proper o peration of the on-chip EVRs while the y generate the core voltage,
the operating frequency shall only be changed in certain steps. This prevents overshoots
and undershoots of the supply voltage.
To avoid the indicated p roblems, recommen ded sequences are pro vided which en sure
the intended operation of the clock system interacting with the power system.
Please refer to the Programmer’s Guide.

4.7.3 External Clock Input Parameters
These parameters specify the external clock generation for the XC2723X. The clock can
be generated in two ways:
• By connecting a crystal or ceramic resonator to pins XTAL1/XTAL2.
• By supplyi ng an external clock signal. This clock signal can be suppl ied 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

oscillation allowance (negative resistance) in the final target system (layout) to
determine th e op ti mu m parameters for oscillator operation.
The manufacturers of crystals and ceramic resonators offer an oscillator

4.7.4 Pad Properties
The output pad drivers of the XC2723X can operate in several user-selectable modes.
Strong driver mode allows controlling external components requiring higher currents
such as power bridges or LEDs. Reducing th e 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. th e 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 sub j ect to p roduction test but verified by design and/or
characterization.
Note: Operating Conditions apply.

Package and Reliability

5 Package and Reliability
The XC2000 Family devices use the package type:
• PG-VQFN (Plastic Green - Very Thin Profile Quad Flat Non-Leaded Packag e)
The following specifications must be regarded to ensure proper integration of the
XC2723X 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 con nect the exposed pad to
the board ground, independent of the thermal require ments.
Board layout examples are given in an applica tion note.
Package Compatibility Considerations
The XC2723X 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 XC2723X in a system, the total heat generated in the chip must be
dissipated to the ambient environment to prevent overheating and the resulting the rma l
damage.
The maximum heat that can be dissipated depend s 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
