Functional Description
The architecture of the XE167 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 operation of several subsystems of the XE167.
The block diagram gives an overview of the on-chip components and the advanced
internal bus structure of the XE167.

XE166 Family Derivatives
Functional Description
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 64 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 chosen derivative (see Table 1).
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.
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.
1 Kbyte of on-chip Stand-By SRAM (SBRAM) provides 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.

XE167x
XE166 Family Derivatives
Functional Description
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 XE166 Family. In order to 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 5) of external RAM and/or
ROM can be connected to the microcontroller. The External Bus Interface also provides
access to external peripherals.
Up to 768 Kbytes of on-chip Flash memory store code, constant data, and control
data. The on-chip Flash memory consists of up to three modules with a maximum
capacity of 256 Kbytes each. 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 derivative (see
Table 1).
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 4.5.
1) To save control bits, sectors are clustered for protection purposes, they remain separate for
programming/erasing.

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.
Up to five external CS signals (four 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.
A HOLD/HLDA protocol is available for bus arbitration; this allows the sharing of external
resources with other bus masters. The bus arbitration is enabled by software, after which
pins P3.0 … P3.2 (BREQ, HLDA, HOLD) are automatically controlled by the EBC. In
Master Mode (default after reset) the HLDA pin is an output. In Slave Mode pin HLDA is
switched to be an input. This allows the direct connection of the slave controller to
another master controller without glue logic.
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.

XE167x
XE166 Family Derivatives
Functional Description
With this hardware most XE167 instructions can be executed in a single machine cycle
of 12.5 ns with an 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 XE167 instruction set. This includes the following

Interrupt System
With a minimum interrupt response time of 7/111) CPU clocks (in the case of internal
program execution), the XE167 can react quickly to the occurrence of non-deterministic
events.
The architecture of the XE167 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).
Where in a standard interrupt service the current program execution is suspended and
a branch to the interrupt vector table is performed, just one cycle is ‘stolen’ from the
current CPU activity to perform a 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
XE167 has eight PEC channels, each whith fast interrupt-driven data transfer
capabilities.
Each of the possible interrupt nodes has a separate control register containing an
interrupt request flag, an interrupt enable flag and an interrupt priority bitfield. Each node
can be programmed by its related register to one of sixteen interrupt priority levels. Once
accepted by the CPU, an interrupt service can only be interrupted by a higher-priority
service request. For standard interrupt processing, each possible interrupt node has a
dedicated vector location.
Fast external interrupt inputs can service external interrupts with high-precision
requirements. These fast interrupt inputs feature programmable edge detection (rising
edge, falling edge, or both edges).
Software interrupts are supported by the ‘TRAP’ instruction in combination with an
individual trap (interrupt) number.
Table 6 shows all of the possible XE167 interrupt sources and the corresponding
hardware-related interrupt flags, vectors, vector locations and trap (interrupt) numbers.
Note: Interrupt nodes which are not assigned to peripherals (unassigned nodes) may be
used to generate software-controlled interrupt requests by setting the respective
interrupt request bit (xIR).

Functional Description
The XE167 includes an excellent mechanism to identify and process exceptions or error
conditions that arise during run-time, the so-called ‘Hardware Traps’. A hardware trap
causes an immediate non-maskable system reaction similar to a standard interrupt
service (branching 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.
Table 7 shows all possible exceptions or error conditions that can arise during runtime:

On-Chip Debug Support (OCDS)
The On-Chip Debug Support system built into the XE167 provides a broad range of
debug and emulation features. User software running on the XE167 can be debugged
within the target system environment.
The OCDS is controlled by an external debugging device via the debug interface. This
consists 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 (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 data can be obtained via the debug interface, or via the external bus interface
for increased performance.
The JTAG interface uses four interface signals, to communicate with external circuitry.
The debug interface can be amended with two optional break lines.

Capture/Compare Unit (CAPCOM2)
The CAPCOM2 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 CAPCOM2 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 (T7/T8) with reload registers provide two independent time bases for
the capture/compare register array.
The input clock for the timers is programmable to a number of prescaled values of the
internal system clock. It may also be derived from an overflow/underflow of timer T6 in
module GPT2. This provides a wide range for the timer period and resolution while
allowing precise adjustments for application-specific requirements. An external count
input for CAPCOM2 timer T7 allows event scheduling for the capture/compare registers
with respect to external events.
The capture/compare register array contains 16 dual purpose capture/compare
registers. Each may be individually allocated to either CAPCOM2 timer T7 or T8 and
programmed for a capture or compare function.
Each register of the CAPCOM2 module has one port pin associated with it. This serves
as an input pin to trigger the capture function or as an output pin to indicate the
occurrence of a compare event.

XE166 Family Derivatives
Functional Description
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 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 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 compare mode selected.

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.

XE166 Family Derivatives
Functional Description
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 (TxEUD). 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 XE167 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.

A/D Converters
For analog signal measurement, up to two 10-bit A/D converters (ADC0, ADC1) with
16 + 8 multiplexed input channels and a sample and hold circuit have been integrated
on-chip. They 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 XE167 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, such as limit checking or result accumulation, reduce the
number of required CPU access operations allowing the precise evaluation of
analoginputs (high conversion rate) even at a low CPU speed.
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 under
software control. This can be selected for each pin separately with registers P5_DIDIS
and P15_DIDIS (Port x Digital Input Disable).
The Auto-Power-Down feature of the A/D converters minimizes the power consumption
when no conversion is in progress.

Universal Serial Interface Channel Modules (USIC)
The XE167 includes up to three USIC modules (USIC0, USIC1, USIC2), each providing
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.

MultiCAN Module
The MultiCAN module contains up to five 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 128 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.
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.

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).
3.14
Clock Generation
The Clock Generation Unit can generate the system clock signal fSYS for the XE167 from
a number of external or internal clock sources:
•
•
•
•
External clock signals with pad or core voltage levels
External crystal using the on-chip oscillator
On-chip clock source for operation without crystal
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 or from the on-chip clock source.
See also Section 4.6.2.
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.

Parallel Ports
The XE167 provides up to 118 I/O lines which are organized into 11 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 9.
All port lines that are not used for alternate functions may be used as general purpose
I/O lines.

See Table 1
1) If both core power domains are clocked, the difference between the power supply voltages must be less than
10 mV. This condition imposes additional constraints when using external power supplies.
Do not combine internal and external supply of different core power domains.
Do not supply the core power domains with two independent external voltage regulators. The simplest method
is to supply both power domains directly via a single external power supply.
2) Performance of pad drivers, A/D Converter, and Flash module depends on VDDP
.
If the external supply voltage VDDP becomes lower than the specified operating range, a power reset must be
generated. Otherwise, the core supply voltage VDDI may rise above its specified operating range due to
parasitic effects.
This power reset can be generated by the on-chip SWD. If the SWD is disabled the power reset must be
generated by activating the PORST input.
3) 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).
4) Not subject to production test - verified by design/characterization.
5) An overload current (IOV) through a pin injects an error current (IINJ) into the adjacent pins. This error current
adds to that pin’s leakage current (IOZ). The value of the error current depends on the overload current and is
defined by the overload coupling factor KOV. The polarity of the injected error current is reversed from 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.
6) 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).
7) 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 Ω. 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.
8) The operating frequency range may be reduced for specific types of the XE167. This is indicated in the
device designation (…FxxL). 80-MHz devices are marked …F80L.

DC Parameters
These parameters are static or average values that may be exceeded during switching
transitions (e.g. output current).
The XE167 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 XE167 are designed to operate in various driver modes. The DC
parameter specifications refer to the current limits in Table 13.

4) 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.
5) 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.
6) An additional error current (IINJ) will flow if an overload current flows through an adjacent pin. Please refer to

7) The given values are worst-case values. In production test, this leakage current is only tested at 125°C; other

the enabled pull device: VPIN ≤ VIL for a pullup; VPIN ≥ VIH for a pulldown.
These values apply to the fixed pull-devices in dedicated pins and to the user-selectable pull-devices in
general purpose IO pins.

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) The maximum deliverable output current of a port driver depends on the selected output driver mode, see

4) 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.
5) 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.
6) 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
.
The leakage current value is not tested in the lower voltage range but only in the upper voltage range. This
parameter is ensured by correlation.
7) The given values are worst-case values. In production test, this leakage current is only tested at 125°C; other

Power Consumption
The power consumed by the XE167 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 (Table 16) and leakage current ILK (Table 17) must be added:
I
DDP = 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, see parameter ICC in Table 20.

TA must be taken into account. As this fraction of the supply current does not depend on device activity, it must
be added to other power consumption values.

1) TUE is tested at VAREFx = VDDPA, VAGND = 0 V. It is verified by design for all other voltages within the defined
voltage range.
The specified TUE is valid only if the absolute sum of input overload currents on Port 5 or Port 15 pins (see
I
OV specification) does not exceed 10 mA, and if VAREF and VAGND remain stable during the measurement time.
2) VAIN may exceed VAGND or VAREFx up to the absolute maximum ratings. However, the conversion result in these
cases will be X000H or X3FFH, respectively.
3) The limit values for fADCI must not be exceeded when selecting the peripheral frequency and the prescaler
setting.
4) This parameter includes the sample time (also the additional sample time specified by STC), the time to
determine the digital result and the time to load the result register with the conversion result.
Values for the basic clock tADCI depend on programming and are found in Table 19.
5) The total unadjusted error TUE is the maximum deviation from the ideal ADC transfer curve, not the sum of
individual errors.

7) These parameter values cover the complete operating range. Under relaxed operating conditions
(temperature, supply voltage) typical values can be used for calculation. At room temperature and nominal
supply voltage the following typical values can be used:
CAINTtyp = 12 pF, CAINStyp = 5 pF, RAINtyp = 1.0 kΩ, CAREFTtyp = 15 pF, CAREFStyp = 10 pF, RAREFtyp = 1.0 kΩ.

1) Programming and erase times depend on the internal Flash clock source. The control state machine needs a
few system clock cycles. This requirement is only relevant for extremely low system frequencies.
In the XE167 erased areas must be programmed completely (with actual code/data or dummy values) before
that area is read.
2) A maximum of 64 Flash sectors can be cycled 15,000 times. For all other sectors the limit is 1,000 cycles.
3) This parameter limits the number of subsequent programming operations within a physical sector. The drain
disturb limit is applicable if wordline erase is used repeatedly. For normal sector erase/program cycles this
limit will not be violated.
Access to the XE167 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.

Definition of Internal Timing
The internal operation of the XE167 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 XE167.

Note: The example of PLL operation shown in Figure 18 uses a PLL factor of 1:4; the

The specification of the external timing (AC Characteristics) depends on the period of the
system clock (TCS).

XE166 Family Derivatives
Electrical Parameters
Direct Drive
When direct drive operation is selected (SYSCON0.CLKSEL = 11B), the system clock is
derived directly from the input clock signal CLKIN1:
f
SYS = 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):
f
SYS = 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:
f
SYS = fOSC / 1024.
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
.

Electrical Parameters
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 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]
f
SYS 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 = 20 pF (see Table 12).
The maximum peak-to-peak noise on the pad supply voltage (measured between
VDDPB pin 100/144 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.
Different frequency bands can be selected for the VCO so that the operation of the PLL
can be adjusted to a wide range of input and output frequencies:

Electrical Parameters
Wakeup Clock
When wakeup operation is selected (SYSCON0.CLKSEL = 00B), the system clock is
derived from the low-frequency wakeup clock source:
f
SYS = fWU.
In this mode, a basic functionality can be maintained without requiring an external clock
source and while minimizing the power consumption.
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 bitfields, 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.
To avoid the indicated problems, recommended sequences are provided which ensure
the intended operation of the clock system interacting with the power system.
Please refer to the Programmer’s Guide.

External Clock Input Parameters
These parameters specify the external clock generation for the XE167. 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.
In 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 … t4) are only valid for an external clock
input signal.

Variable Memory Cycles
External bus cycles of the XE167 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.

Electrical Parameters
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.

Thermal Considerations
When operating the XE167 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 125 °C.
The difference between junction temperature and ambient temperature is determined by
∆T = (PINT + PIOSTAT + PIODYN) × RΘJA
The internal power consumption is defined as
P
INT = VDDP × IDDP (see Section 4.2.3).
The static external power consumption caused by the output drivers is defined as
IOSTAT = Σ((VDDP-VOH) × IOH) + Σ(VOL × IOL)
P
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
