Ordering Information  
The ordering code for Infineon microcontrollers provides an exact reference to the  
required product. This ordering code identifies:  
• the derivative itself, i.e. its function set, the temperature range, and the supply voltage  
• the package and the type of delivery.  
For the available ordering codes for the C164CI please refer to the “Product Catalog  
Microcontrollers”, which summarizes all available microcontroller variants.  
Note: The ordering codes for Mask-ROM versions are defined for each product after  
verification of the respective ROM code.  
Introduction  
The C164CI derivatives of the Infineon C166 Family of full featured single-chip CMOS  
microcontrollers are especially suited for cost sensitive applications. They combine high  
CPU performance (up to 12.5 million instructions per second) with high peripheral  
functionality and enhanced IO-capabilities. They also provide clock generation via PLL  
and various on-chip memory modules such as program ROM or OTP, internal RAM, and  
extension RAM.

To clock the device from an external source, drive XTAL1,  
while leaving XTAL2 unconnected. Minimum and maximum

RSTIN 69  
I/O  
Reset Input with Schmitt-Trigger characteristics. A low level  
at this pin while the oscillator is running resets the C164CI.  
An internal pullup resistor permits power-on reset using only  
a capacitor connected to VSS.  
A spike filter suppresses input pulses <10 ns. Input pulses  
>100 ns safely pass the filter. The minimum duration for a  
safe recognition should be 100 ns + 2 CPU clock cycles.  
In bidirectional reset mode (enabled by setting bit BDRSTEN  
in register SYSCON) the RSTIN line is internally pulled low  
for the duration of the internal reset sequence upon any reset  
(HW, SW, WDT). See note below this table.

Internal Reset Indication Output. This pin is set to a low level

a watchdog timer reset. RSTOUT remains low until the EINIT  
(end of initialization) instruction is executed.  
NMI  
Non-Maskable Interrupt Input. A high to low transition at this  
pin causes the CPU to vector to the NMI trap routine. When  
the PWRDN (power down) instruction is executed, the NMI  
pin must be low in order to force the C164CI to go into power  
down mode. If NMI is high, when PWRDN is executed, the  
part will continue to run in normal mode.  
If not used, pin NMI should be pulled high externally.

several assignments can be selected.  
Note: The following behavioural differences must be observed when the bidirectional  
reset is active:  
Bit BDRSTEN in register SYSCON cannot be changed after EINIT and is cleared  
automatically after a reset.  
The reset indication flags always indicate a long hardware reset.  
The PORT0 configuration is treated as if it were a hardware reset. In particular, the  
bootstrap loader may be activated when P0L.4 is low.  
Pin RSTIN may only be connected to external reset devices with an open drain output  
driver.  
A short hardware reset is extended to the duration of the internal reset sequence.

Functional Description  
The architecture of the C164CI combines advantages of both RISC and CISC  
processors and of advanced peripheral subsystems in a very well-balanced way. In  
addition the on-chip memory blocks allow the design of compact systems with maximum  
performance.  
The following block diagram gives an overview of the different on-chip components and  
of the advanced, high bandwidth internal bus structure of the C164CI.  
Note: All time specifications refer to a CPU clock of 25 MHz

The program memory, the internal RAM (IRAM) and the set of generic peripherals are  
connected to the CPU via separate buses. A fourth bus, the XBUS, connects external  
resources as well as additional on-chip resoures, the X-Peripherals (see Figure 3).  
The XBUS resources (XRAM, CAN) of the C164CI can be enabled or disabled during  
initialization by setting the general X-Peripheral enable bit XPEN (SYSCON.2). Modules  
that are disabled consume neither address space nor port pins.

Memory Organization  
The memory space of the C164CI is configured in a Von Neumann architecture which  
means that code memory, data memory, registers and I/O ports are organized within the  
same linear address space which includes 16 MBytes. The entire memory space can be  
accessed bytewise or wordwise. Particular portions of the on-chip memory have  
additionally been made directly bitaddressable.  
The C164CI incorporates 64 KBytes of on-chip OTP memory or 64/48 KBytes of on-chip  
mask-programmable ROM (not in the ROM-less derivative, of course) for code or  
constant data. The lower 32 KBytes of the on-chip ROM/OTP can be mapped either to  
segment 0 or segment 1.  
The OTP memory can be programmed by the CPU itself (in system, e.g. during booting)  
or directly via an external interface (e.g. before assembly). The programming time is  
approx. 100 µs per word. An external programming voltage VPP = 11.5 V must be  
supplied for this purpose (via pin EA/VPP).  
2 KBytes of on-chip Internal RAM (IRAM) are provided as a storage for user defined  
variables, for the system stack, general purpose register banks and even for code. A  
register bank can consist of up to 16 wordwide (R0 to R15) and/or bytewide (RL0, RH0,  
, RL7, RH7) so-called General Purpose Registers (GPRs).  
1024 bytes (2 × 512 bytes) of the address space are reserved for the Special Function  
Register areas (SFR space and ESFR space). SFRs are wordwide registers which are  
used for controlling and monitoring functions of the different on-chip units. Unused SFR  
addresses are reserved for future members of the C166 Family.  
2 KBytes of on-chip Extension RAM (XRAM) are provided to store user data, user  
stacks, or code. The XRAM is accessed like external memory and therefore cannot be  
used for the system stack or for register banks and is not bitaddressable. The XRAM  
permits 16-bit accesses with maximum speed.  
In order to meet the needs of designs where more memory is required than is provided  
on chip, up to 4 MBytes of external RAM and/or ROM can be connected to the  
microcontroller.  
Data Sheet

V2.0, 2001-05  
C164CI/SI  
C164CL/SL  
External Bus Controller  
All of the external memory accesses are performed by a particular on-chip External Bus  
Controller (EBC). It can be programmed either to Single Chip Mode when no external  
memory is required, or to one of four different external memory access modes, which are  
as follows:  
16-/18-/20-/22-bit Addresses, 16-bit Data, Demultiplexed  
16-/18-/20-/22-bit Addresses, 16-bit Data, Multiplexed  
16-/18-/20-/22-bit Addresses, 8-bit Data, Multiplexed  
16-/18-/20-/22-bit Addresses, 8-bit Data, Demultiplexed  
In the demultiplexed bus modes, addresses are output on PORT1 and data is input/  
output on PORT0 or P0L, respectively. In the multiplexed bus modes both addresses  
and data use PORT0 for input/output.  
Important timing characteristics of the external bus interface (Memory Cycle Time,  
Memory Tri-State Time, Length of ALE and Read Write Delay) have been made  
programmable to allow the user the adaption of a wide range of different types of  
memories and external peripherals.  
In addition, up to 4 independent address windows may be defined (via register pairs  
ADDRSELx / BUSCONx) which control the access to different resources with different  
bus characteristics. These address windows are arranged hierarchically where  
BUSCON4 overrides BUSCON3 and BUSCON2 overrides BUSCON1. All accesses to  
locations not covered by these 4 address windows are controlled by BUSCON0.  
Up to 4 external CS signals (3 windows plus default) can be generated in order to save  
external glue logic. The C164CI offers the possibility to switch the CS outputs to an  
unlatched mode. In this mode the internal filter logic is switched off and the CS signals  
are directly generated from the address. The unlatched CS mode is enabled by setting  
CSCFG (SYSCON.6).  
For applications which require less than 4 MBytes of external memory space, this  
address space can be restricted to 1 MByte, 256 KByte, or to 64 KByte. In this case  
Port 4 outputs four, two, or no address lines at all. It outputs all 6 address lines, if an  
address space of 4 MBytes is used.  
Note: When the on-chip CAN Module is used with the interface lines assigned to Port 4,  
the CAN lines override the segment address lines and the segment address  
output on Port 4 is therefore limited to 4 bits i.e. address lines A19 … A16.

C164CL/SL  
Central Processing Unit (CPU)  
The main core of the CPU consists of a 4-stage instruction pipeline, a 16-bit arithmetic  
and logic unit (ALU) and dedicated SFRs. Additional hardware has been spent for a  
separate multiply and divide unit, a bit-mask generator and a barrel shifter.  
Based on these hardware provisions, most of the C164CIs instructions can be executed  
in just one machine cycle which requires 2 CPU clocks (4 TCL). For example, shift and  
rotate instructions are always processed during one machine cycle independent of the  
number of bits to be shifted. All multiple-cycle instructions have been optimized so that  
they can be executed very fast as well: branches in 2 cycles, a 16 × 16 bit multiplication  
in 5 cycles and a 32-/16-bit division in 10 cycles. Another pipeline optimization, the so-  
called Jump Cache, reduces the execution time of repeatedly performed jumps in a loop  
from 2 cycles to 1 cycle.

C164CL/SL  
The CPU has a register context consisting of up to 16 wordwide GPRs at its disposal.  
These 16 GPRs are physically allocated within the on-chip RAM area. A Context Pointer  
(CP) register determines the base address of the active register bank to be accessed by  
the CPU at any time. The number of register banks 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 1024 words is provided as a storage for temporary data. The  
system stack is allocated in the on-chip RAM area, and it is accessed by the CPU via the  
stack pointer (SP) register. Two separate SFRs, STKOV and STKUN, are implicitly  
compared against the stack pointer value upon each stack access for the detection of a  
stack overflow or underflow.  
The high performance offered by the hardware implementation of the CPU can efficiently  
be utilized by a programmer via the highly efficient C164CI instruction set which includes  
the following instruction classes:  
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

The basic instruction length is either 2 or 4 bytes. Possible operand types are bits, bytes  
and words. A variety of direct, indirect or immediate addressing modes are provided to  
specify the required operands.

C164CL/SL  
Interrupt System  
With an interrupt response time within a range from just 5 to 12 CPU clocks (in case of  
internal program execution), the C164CI is capable of reacting very fast to the  
occurrence of non-deterministic events.  
The architecture of the C164CI supports several mechanisms for fast and flexible  
response to service requests that can be generated from various sources internal or  
external to the microcontroller. Any of these interrupt requests can be programmed to  
being serviced by the Interrupt Controller or by the Peripheral Event Controller (PEC).  
In contrast to a standard interrupt service where the current program execution is  
suspended and a branch to the interrupt vector table is performed, just one cycle is  
stolenfrom 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 or the destination pointer. An individual PEC transfer  
counter is implicity 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 very  
well suited, for example, for supporting the transmission or reception of blocks of data.  
The C164CI has 8 PEC channels each of which offers such fast interrupt-driven data  
transfer capabilities.  
A separate control register which contains an interrupt request flag, an interrupt enable  
flag and an interrupt priority bitfield exists for each of the possible interrupt sources. Via  
its related register, each source can be programmed to one of sixteen interrupt priority  
levels. Once having been accepted by the CPU, an interrupt service can only be  
interrupted by a higher prioritized service request. For the standard interrupt processing,  
each of the possible interrupt sources has a dedicated vector location.  
Fast external interrupt inputs are provided to 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 means of the TRAPinstruction in combination with  
an individual trap (interrupt) number.  
Table 3 shows all of the possible C164CI interrupt sources and the corresponding  
hardware-related interrupt flags, vectors, vector locations and trap (interrupt) numbers.  
Note: Interrupt nodes which are not used by associated peripherals, may be used to  
generate software controlled interrupt requests by setting the respective interrupt  
request bit (xIR).

The C164CI also provides an excellent mechanism to identify and to process exceptions  
or error conditions that arise during run-time, so-called Hardware Traps. Hardware  
traps cause immediate non-maskable system reaction which is similar to a standard  
interrupt service (branching to a dedicated vector table location). The occurence of a  
hardware trap is additionally signified by an individual bit in the trap flag register (TFR).  
Except when another higher prioritized trap service is in progress, a hardware trap will  
interrupt any actual program execution. In turn, hardware trap services can normally not  
be interrupted by standard or PEC interrupts.  
Table 4 shows all of the possible exceptions or error conditions that can arise during run-

The Capture/Compare Unit CAPCOM2  
The general purpose CAPCOM2 unit supports generation and control of timing  
sequences on up to 8 channels with a maximum resolution of 16 TCL. The CAPCOM  
units are typically used to handle high speed I/O tasks such as pulse and waveform  
generation, pulse width modulation (PMW), Digital to Analog (D/A) conversion, software  
timing, or time recording relative to external events.  
Two 16-bit timers (T7/T8) with reload registers provide two independent time bases for  
the capture/compare register array.  
Each dual purpose capture/compare register, which may be individually allocated to  
either CAPCOM timer and programmed for capture or compare function, has 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.

The Capture/Compare Unit CAPCOM6  
The CAPCOM6 unit supports generation and control of timing sequences on up to three  
16-bit capture/compare channels plus one 10-bit compare channel.  
In compare mode the CAPCOM6 unit provides two output signals per channel which  
have inverted polarity and non-overlapping pulse transitions. The compare channel can  
generate a single PWM output signal and is further used to modulate the capture/  
compare output signals.  
In capture mode the contents of compare timer 12 is stored in the capture registers upon  
a signal transition at pins CCx.  
Compare timers T12 (16-bit) and T13 (10-bit) are free running timers which are clocked  
by the prescaled CPU clock.

General Purpose Timer (GPT) Unit  
The GPT unit represents a very flexible multifunctional timer/counter structure which  
may be used for many different time related tasks such as event timing and counting,  
pulse width and duty cycle measurements, pulse generation, or pulse multiplication.  
The GPT unit incorporates three 16-bit timers. Each timer may operate independently in  
a number of different modes, or may be concatenated with another timer.  
Each of the three timers T2, T3, T4 of module GPT1 can be configured individually for  
one of four basic modes of operation, which are Timer, Gated Timer, Counter, and  
Incremental Interface Mode. In Timer Mode, the input clock for a timer is derived from  
the CPU clock, divided by a programmable prescaler, while Counter Mode allows a timer  
to be clocked 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 gatelevel on an external input pin. For these  
purposes, each timer has one associated port pin (TxIN) which serves as gate or clock  
input. The maximum resolution of the timers in module GPT1 is 16 TCL.  
The count direction (up/down) for each timer is programmable by software or may  
additionally be altered dynamically by an external signal on a port pin (TxEUD) to  
facilitate e.g. position tracking.  
In Incremental Interface Mode the GPT1 timers (T2, T3, T4) can be directly connected  
to the incremental position sensor signals A and B via their respective inputs TxIN and  
TxEUD. Direction and count signals are internally derived from these two input signals,  
so 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 over-  
flow/underflow. The state of this latch may be used internally to clock timers T2 and T4  
for measuring long time periods with high resolution.  
In addition to their basic operating modes, timers T2 and T4 may be configured as reload  
or capture registers for timer T3. When used as capture or reload registers, timers T2  
and T4 are stopped. The contents of timer T3 is captured into T2 or T4 in response to a  
signal at their associated input pins (TxIN). Timer T3 is reloaded with the contents of T2  
or T4 triggered either by an external signal or by a selectable state transition of its toggle  
latch T3OTL.

Real Time Clock  
The Real Time Clock (RTC) module of the C164CI consists of a chain of 3 divider blocks,  
a fixed 8:1 divider, the reloadable 16-bit timer T14, and the 32-bit RTC timer (accessible  
via registers RTCH and RTCL). The RTC module is directly clocked with the on-chip  
oscillator frequency divided by 32 via a separate clock driver (fRTC = fOSC/32) and is  
therefore independent from the selected clock generation mode of the C164CI. All timers  
count up.  
The RTC module can be used for different purposes:  
System clock to determine the current time and date

A/D Converter  
For analog signal measurement, a 10-bit A/D converter with 8 multiplexed input channels  
and a sample and hold circuit has been integrated on-chip. It uses the method of  
successive approximation. The sample time (for loading the capacitors) and the  
conversion time is programmable and can so be adjusted to the external circuitry.  
Overrun error detection/protection is provided for the conversion result register  
(ADDAT): either an interrupt request will be generated when the result of a previous  
conversion has not been read from the result register at the time the next conversion is  
complete, or the next conversion is suspended in such a case until the previous result  
has been read.  
For applications which require less than 8 analog input channels, the remaining channel  
inputs can be used as digital input port pins.  
The A/D converter of the C164CI supports four different conversion modes. In the  
standard Single Channel conversion mode, the analog level on a specified channel is  
sampled once and converted to a digital result. In the Single Channel Continuous mode,  
the analog level on a specified channel is repeatedly sampled and converted without  
software intervention. In the Auto Scan mode, the analog levels on a prespecified  
number of channels (standard or extension) are sequentially sampled and converted. In  
the Auto Scan Continuous mode, the number of prespecified channels is repeatedly  
sampled and converted. In addition, the conversion of a specific channel can be inserted  
(injected) into a running sequence without disturbing this sequence. This is called  
Channel Injection Mode.  
The Peripheral Event Controller (PEC) may be used to automatically store the  
conversion results into a table in memory for later evaluation, without requiring the  
overhead of entering and exiting interrupt routines for each data transfer.  
After each reset and also during normal operation the ADC automatically performs  
calibration cycles. This automatic self-calibration constantly adjusts the converter to  
changing operating conditions (e.g. temperature) and compensates process variations.  
These calibration cycles are part of the conversion cycle, so they do not affect the normal  
operation of the A/D converter.  
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 IO or input stages  
under software control. This can be selected for each pin separately via register P5DIDIS  
(Port 5 Digital Input Disable).

Serial Channels  
Serial communication with other microcontrollers, processors, terminals or external  
peripheral components is provided by two serial interfaces with different functionality, an  
Asynchronous/Synchronous Serial Channel (ASC0) and a High-Speed Synchronous  
Serial Channel (SSC).  
The ASC0 is upward compatible with the serial ports of the Infineon 8-bit microcontroller  
families and supports full-duplex asynchronous communication at up to 781 Kbit/s and  
half-duplex synchronous communication at up to 3.1 Mbit/s (@ 25 MHz CPU clock).  
A dedicated baud rate generator allows to set up all standard baud rates without  
oscillator tuning. For transmission, reception and error handling 4 separate interrupt  
vectors are provided. In asynchronous mode, 8- or 9-bit data frames are transmitted or  
received, preceded by a start bit and terminated by one or two stop bits. For  
multiprocessor communication, a mechanism to distinguish address from data bytes has  
been included (8-bit data plus wake up bit mode).  
In synchronous mode, the ASC0 transmits or receives bytes (8 bits) synchronously to a  
shift clock which is generated by the ASC0. The ASC0 always shifts the LSB first. A loop  
back option is available for testing purposes.  
A number of optional hardware error detection capabilities has been included to increase  
the reliability of data transfers. A parity bit can automatically be generated on  
transmission or be checked on reception. Framing error detection allows to recognize  
data frames with missing stop bits. An overrun error will be generated, if the last  
character received has not been read out of the receive buffer register at the time the  
reception of a new character is complete.  
The SSC supports full-duplex synchronous communication at up to 6.25 Mbit/s  
(@ 25 MHz CPU clock). It may be configured so it interfaces with serially linked  
peripheral components. A dedicated baud rate generator allows to set up all standard  
baud rates without oscillator tuning. For transmission, reception and error handling  
3 separate interrupt vectors are provided.  
The SSC transmits or receives characters of 2 16 bits length synchronously to a shift  
clock which can be generated by the SSC (master mode) or by an external master (slave  
mode). The SSC can start shifting with the LSB or with the MSB and allows the selection  
of shifting and latching clock edges as well as the clock polarity.  
A number of optional hardware error detection capabilities has been included to increase  
the reliability of data transfers. Transmit and receive error supervise the correct handling  
of the data buffer. Phase and baudrate error detect incorrect serial data.

CAN-Module  
The integrated CAN-Module handles the completely autonomous transmission and  
reception of CAN frames in accordance with the CAN specification V2.0 part B (active),  
i.e. the on-chip CAN-Modules can receive and transmit standard frames with 11-bit  
identifiers as well as extended frames with 29-bit identifiers.  
The module provides Full CAN functionality on up to 15 message objects. Message  
object 15 may be configured for Basic CAN functionality. Both modes provide separate  
masks for acceptance filtering which allows to accept a number of identifiers in Full CAN  
mode and also allows to disregard a number of identifiers in Basic CAN mode. All  
message objects can be updated independent from the other objects and are equipped  
for the maximum message length of 8 bytes.  
The bit timing is derived from the XCLK and is programmable up to a data rate of 1 Mbit/  
s. Each CAN-Module uses two pins of Port 4 or Port 8 to interface to an external bus  
transceiver. The interface pins are assigned via software.  
Note: When the CAN interface is assigned to Port 4, the respective segment address  
lines on Port 4 cannot be used. This will limit the external address space.  
Watchdog Timer  
The Watchdog Timer represents 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 a reset of the chip, and can only be  
disabled in the time interval until the EINIT (end of initialization) instruction has been  
executed. Thus, the chips start-up procedure is always monitored. The software has to  
be designed to service the Watchdog Timer before it overflows. If, due to hardware or  
software related failures, the software fails to do so, the Watchdog Timer overflows and  
generates an internal hardware reset and pulls the RSTOUT pin low in order to allow  
external hardware components to be reset.  
The Watchdog Timer is a 16-bit timer, clocked with the system clock divided by 2/4/128/  
256. The high byte of the Watchdog Timer register can be 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 high byte of the  
Watchdog Timer is reloaded. Thus, time intervals between 20 µs and 336 ms can be  
monitored (@ 25 MHz).  
The default Watchdog Timer interval after reset is 5.24 ms (@ 25 MHz).

Parallel Ports  
The C164CI provides up to 59 I/O lines which are organized into five input/output ports  
and one input port. All port lines are bit-addressable, and all input/output lines are  
individually (bit-wise) programmable as inputs or outputs via direction registers. The I/O  
ports are true bidirectional ports which are switched to high impedance state when  
configured as inputs. The output drivers of three I/O ports can be configured (pin by pin)  
for push/pull operation or open-drain operation via control registers. During the internal  
reset, all port pins are configured as inputs.  
The input threshold of Port 3, Port 4, and Port 8 is selectable (TTL or CMOS like), where  
the special CMOS like input threshold reduces noise sensitivity due to the input  
hysteresis. The input threshold may be selected individually for each byte of the  
respective ports.  
All port lines have programmable alternate input or output functions associated with  
them. All port lines that are not used for these alternate functions may be used as general  
purpose IO lines.  
PORT0 and PORT1 may be used as address and data lines when accessing external  
memory, while Port 4 outputs the additional segment address bits A21/19/17 A16 and  
the optional chip select signals in systems where segmentation is enabled to access  
more than 64 KBytes of memory.  
Ports P1L, P1H, and P8 are associated with the capture inputs or compare outputs of  
the CAPCOM units and/or serve as external interrupt inputs.  
Port 3 includes alternate functions of timers, serial interfaces, the optional bus control  
signal BHE/WRH, and the system clock output CLKOUT (or the programmable  
frequency output FOUT).  
Port 5 is used for the analog input channels to the A/D converter or timer control signals.  
The edge characteristics (transition time) and driver characteristics (output current) of  
the C164CIs port drivers can be selected via the Port Output Control registers  
(POCONx).

Oscillator Watchdog  
The Oscillator Watchdog (OWD) monitors the clock signal generated by the on-chip  
oscillator (either with a crystal or via external clock drive). For this operation the PLL  
provides a clock signal which is used to supervise transitions on the oscillator clock. This  
PLL clock is independent from the XTAL1 clock. When the expected oscillator clock  
transitions are missing the OWD activates the PLL Unlock/OWD interrupt node and  
supplies the CPU with the PLL clock signal. Under these circumstances the PLL will  
oscillate with its basic frequency.  
In direct drive mode the PLL base frequency is used directly (fCPU = 2 5 MHz).  
In prescaler mode the PLL base frequency is divided by 2 (fCPU = 1 2.5 MHz).  
Note: The CPU clock source is only switched back to the oscillator clock after a  
hardware reset.  
The oscillator watchdog can be disabled by setting bit OWDDIS in register SYSCON.  
In this case (OWDDIS = 1) the PLL remains idle and provides no clock signal, while the  
CPU clock signal is derived directly from the oscillator clock or via prescaler or SDD. Also  
no interrupt request will be generated in case of a missing oscillator clock.  
Note: At the end of a reset bit OWDDIS reflects the inverted level of pin RD at that time.  
Thus the oscillator watchdog may also be disabled via hardware by (externally)  
pulling the RD line low upon a reset, similar to the standard reset configuration via  
PORT0.

Power Management  
The C164CI provides several means to control the power it consumes either at a given  
time or averaged over a certain timespan. Three mechanisms can be used (partly in  
parallel):  
Power Saving Modes switch the C164CI into a special operating mode (control via  
instructions).  
Idle Mode stops the CPU while the peripherals can continue to operate.  
Sleep Mode and Power Down Mode stop all clock signals and all operation (RTC may  
optionally continue running). Sleep Mode can be terminated by external interrupt  
signals.  
Clock Generation Management controls the distribution and the frequency of  
internal and external clock signals (control via register SYSCON2).  
Slow Down Mode lets the C164CI run at a CPU clock frequency of fOSC/1 32 (half  
for prescaler operation) which drastically reduces the consumed power. The PLL can  
be optionally disabled while operating in Slow Down Mode.  
External circuitry can be controlled via the programmable frequency output FOUT.  
Peripheral Management permits temporary disabling of peripheral modules (control  
via register SYSCON3).  
Each peripheral can separately be disabled/enabled. A group control option disables  
a major part of the peripheral set by setting one single bit.  
The on-chip RTC supports intermittend operation of the C164CI by generating cyclic  
wakeup signals. This offers full performance to quickly react on action requests while the  
intermittend sleep phases greatly reduce the average power consumption of the system.

Note: Stresses above those listed under Absolute Maximum Ratingsmay cause  
permanent damage to the device. This is a stress rating only and 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 extended periods may affect device reliability.  
During absolute maximum rating overload conditions (VIN > VDD or VIN < VSS) the  
voltage on VDD pins with respect to ground (VSS) must not exceed the values  
defined by the absolute maximum ratings.

Overload conditions occur if the standard operatings conditions are exceeded, i.e. the voltage on any pin  
exceeds the specified range (i.e. VOV > VDD + 0.5 V or VOV < VSS - 0.5 V). The absolute sum of input overload  
currents on all pins may not exceed 50 mA. The supply voltage must remain within the specified limits.

AC Characteristics  
Definition of Internal Timing  
The internal operation of the C164CI is controlled by the internal CPU clock fCPU. Both  
edges of the CPU clock can trigger internal (e.g. pipeline) or external (e.g. bus cycles)  
operations.  
The specification of the external timing (AC Characteristics) therefore depends on the  
time between two consecutive edges of the CPU clock, called TCL(see Figure 11).

Generation Mechanisms for the CPU Clock  
The CPU clock signal fCPU can be generated from the oscillator clock signal fOSC via  
different mechanisms. The duration of TCLs and their variation (and also the derived  
external timing) depends on the used mechanism to generate fCPU. This influence must  
be regarded when calculating the timings for the C164CI.  
Note: The example for PLL operation shown in Figure 11 refers to a PLL factor of 4.  
The used mechanism to generate the basic CPU clock is selected by bitfield CLKCFG  
in register RP0H.7-5.  
Upon a long hardware reset register RP0H is loaded with the logic levels present on the  
upper half of PORT0 (P0H), i.e. bitfield CLKCFG represents the logic levels on pins

RSTCON under software control.

generation mode.

Please note that pin P0.15 (corresponding to RP0H.7) is inverted in emulation mode, and thus also in EHM.  
The external clock input range refers to a CPU clock range of 10 25 MHz.  
The maximum frequency depends on the duty cycle of the external clock signal.  
Prescaler Operation  
When prescaler operation is configured (CLKCFG = 001 ) the CPU clock is derived from  
B
the internal oscillator (input clock signal) by a 2:1 prescaler.  
The frequency of fCPU is half the frequency of fOSC and the high and low time of fCPU (i.e.  
the duration of an individual TCL) is defined by the period of the input clock fOSC  
.
The timings listed in the AC Characteristics that refer to TCLs therefore can be  
calculated using the period of fOSC for any TCL.  
Phase Locked Loop  
When PLL operation is configured (via CLKCFG) the on-chip phase locked loop is  
enabled and provides the CPU clock (see Table 11). The PLL multiplies the input  
frequency by the factor F which is selected via the combination of pins P0.15-13 (i.e.  
fCPU = fOSC × F). With every Fth transition of fOSC the PLL circuit synchronizes the CPU  
clock to the input clock. This synchronization is done smoothly, i.e. the CPU clock  
frequency does not change abruptly.  
Data Sheet  
51  
V2.0, 2001-05  
C164CI/SI  
C164CL/SL  
Due to this adaptation to the input clock the frequency of fCPU is constantly adjusted so  
it is locked to fOSC. The slight variation causes a jitter of fCPU which also effects the  
duration of individual TCLs.  
The timings listed in the AC Characteristics that refer to TCLs therefore must be  
calculated using the minimum TCL that is possible under the respective circumstances.  
The actual minimum value for TCL depends on the jitter of the PLL. As the PLL is  
constantly adjusting its output frequency so it corresponds to the applied input frequency  
(crystal or oscillator) the relative deviation for periods of more than one TCL is lower than  
for one single TCL (see formula and Figure 12).  
For a period of N × TCL the minimum value is computed using the corresponding  
deviation D :  
N
(N × TCL)  
= N × TCL  
- D ; D [ns] = (13.3 + N × 6.3)/fCPU [MHz],  
NOM  
N N  
min  
where N = number of consecutive TCLs and 1 N 40.  
So for a period of 3 TCLs @ 25 MHz (i.e. N = 3): D = (13.3 + 3 × 6.3)/25 = 1.288 ns,  
3
and (3TCL)  
= 3TCL  
- 1.288 ns = 58.7 ns (@ fCPU = 25 MHz).  
min  
NOM  
This is especially important for bus cycles using waitstates and e.g. 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 neglectible.  
Note: For all periods longer than 40 TCL the N = 40 value can be used (see Figure 12).

Direct Drive  
When direct drive is configured (CLKCFG = 011 ) the on-chip phase locked loop is  
B
disabled and the CPU clock is directly driven from the internal oscillator with the input  
clock signal.  
The frequency of fCPU directly follows the frequency of fOSC so the high and low time of  
fCPU (i.e. the duration of an individual TCL) is defined by the duty cycle of the input clock  
fOSC  
.
The timings listed below that refer to TCLs therefore must be calculated using the  
minimum TCL that is possible under the respective circumstances. This minimum value  
can be calculated via the following formula:  
TCL  
= 1/fOSC × DC  
(DC = duty cycle)  
min  
min  
For two consecutive TCLs the deviation caused by the duty cycle of fOSC is compensated  
so the duration of 2TCL is always 1/fOSC. The minimum value TCL therefore has to  
min  
be used only once for timings that require an odd number of TCLs (1, 3, ). Timings that  
require an even number of TCLs (2, 4, ) may use the formula 2TCL = 1/fOSC  
.

Note: If the on-chip oscillator is used together with a crystal, the oscillator frequency is  
limited to a range of 4 MHz to 16 MHz.  
It is strongly recommended to measure the oscillation allowance (or margin) in the  
final target system (layout) to determine the optimum parameters for the oscillator  
operation. Please refer to the limits specified by the crystal supplier.  
When driven by an external clock signal it will accept the specified frequency  
range. Operation at lower input frequencies is possible but is guaranteed by  
design only (not 100% tested).

internal resistance of the analog source must allow the capacitance to reach its final voltage level within tS.  
After the end of the sample time tS, changes of the analog input voltage have no effect on the conversion result.  
Values for the sample time tS depend on programming and can be taken from Table 14.  
Sample time and conversion time of the C164CIs A/D Converter are programmable.  
Table 14 should be used to calculate the above timings.  
The limit values for fBC must not be exceeded when selecting ADCTC.

Read data are latched with the same clock edge that triggers the address change and the rising RD edge.  
Therefore address changes before the end of RD have no impact on read cycles.

Notes

Cycle as programmed, including MCTC waitstates (Example shows 0 MCTC WS).  
2)  
3)  
The leading edge of the respective command depends on RW-delay.  
Multiplexed bus modes have a MUX waitstate added after a bus cycle, and an additional MTTC waitstate may  
be inserted here.  
For a multiplexed bus with MTTC waitstate this delay is 2 CLKOUT cycles, for a demultiplexed bus without  
MTTC waitstate this delay is zero.  
The next external bus cycle may start here.

Infineon goes for Business Excellence  
Business excellence means intelligent approaches and clearly  
defined processes, which are both constantly under review and  
ultimately lead to good operating results.  
Better operating results and business excellence mean less  
idleness and wastefulness for all of us, more professional  
success, more accurate information, a better overview and,  
thereby, less frustration and more satisfaction.”
