semiconductor group 10 1998-02 c164ci functional description the c164ci is a low cost downgrade of the high performance microcontroller c167cr with otp or internal rom, reduced peripheral functionality and a high performance capture compare unit with an additional functionality. the architecture of the c164ci combines advantages of both risc and cisc processors and of advanced peripheral subsystems in a very well-balanced way. 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 20 mhz (see definition in the ac characteristics section). figure 3 block diagram 64k internal rom (c164ci-8rm) or otp (c164ci-8em) pll-oscillator progr. multiplier: 0.5; 1; 1.5; 2; 2.5; 3; 4; 5 instr./data full-can interface v2.0b active pec cpu core interrupt bus internal ram 2 kbyte dual port port 8 port 3 port 0 port 4 port 1 16 16 4 16 16 data data wdt port 5 8 c164ci v1.2 cpu c166-core xbus (16-bit non mux data / addresses) external bus (8/16 bit; mux only) & xbus control 16 external instr./data 16 8- channel 10-bit adc usart asc sync. channel (spi) ssc timer 7 timer 8 general purpose capture/compare unit 8-channel 16-bit capture/compare unit (capcom2) capture/compare unit for pwm generation (capcom6) 3/6 capture/compare channels xtal p4.5/can_rxd p4.6/can_txd 9 brg brg 5 16 peripheral data 1 compare channel interrupt controller up to 12 ext. ir timer 13 gpt 1 t 3 t 4 t 2 32 rtc
semiconductor group 11 1998-02 c164ci 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 4 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 kbyte of on-chip rom or otp memory for code or constant data. the otp memory can be programmed by the cpu itself (in system, eg. during booting) or directly via an external interface (eg. before assembly). the programming time is approx. 100 m sec per word. an external programming voltage v pp = 11.5 v must be supplied for this purpose (via pin ea ). 2 kbytes of on-chip internal ram 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 c16x family. 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. 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 two different external memory access modes, which are as follows: C 16-/18-/20-/22-bit addresses, 16-bit data, multiplexed C 16-/18-/20-/22-bit addresses, 8-bit data, multiplexed 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 allow to access 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. 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 to be used the segment address output on port 4 must be limited to 4 bits (ie. a19...a16) in order to enable the alternate function of the can interface pins.
semiconductor group 12 1998-02 c164ci 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 100 ns at 20-mhz cpu clock. 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, allows reducing the execution time of repeatedly performed jumps in a loop from 2 cycles to 1 cycle. figure 4 cpu block diagram mcb02147 cpu sp stkov stkun instr. reg. instr. ptr. exec. unit 4-stage pipeline mdh mdl psw syscon context ptr. mul/div-hw r15 r0 general purpose registers bit-mask gen barrel - shifter alu (16-bit) data page ptr. code seg. ptr. internal ram r15 r0 rom 16 16 32 buscon 0 buscon 1 buscon 2 buscon 3 buscon 4 addrsel 4 addrsel 3 addrsel 2 addrsel 1
semiconductor group 13 1998-02 c164ci the cpu disposes of an actual register context consisting of up to 16 wordwide gprs which 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 a 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 2048 bytes 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: C arithmetic instructions C logical instructions C boolean bit manipulation instructions C compare and loop control instructions C shift and rotate instructions C prioritize instruction C data movement instructions C system stack instructions C jump and call instructions C return instructions C system control instructions C miscellaneous instructions the basic instruction length is either 2 or 4 bytes. possible operand types are bits, bytes and words. a variety of direct, indirect or immediate addressing modes are provided to specify the required operands.
semiconductor group 14 1998-02 c164ci interrupt system with an interrupt response time within a range from just 250 ns to 600 ns (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 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 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 trap instruction in combination with an individual trap (interrupt) number. the following table shows all of the possible c164ci interrupt sources and the corresponding hardware-related interrupt flags, vectors, vector locations and trap (interrupt) numbers: source of interrupt or pec service request request flag enable flag interrupt vector vector location trap number fast external interrupt 0 cc8ir cc8ie cc8int 000060 h 18 h fast external interrupt 1 cc9ir cc9ie cc9int 000064 h 19 h fast external interrupt 2 cc10ie cc10ie cc10int 000068 h 1a h fast external interrupt 3 cc11ie cc11ie cc11int 00006c h 1b h gpt1 timer 2 t2ir t2ie t2int 000088 h 22 h gpt1 timer 3 t3ir t3ie t3int 00008c h 23 h

semiconductor group 16 1998-02 c164ci 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. the following table shows all of the possible exceptions or error conditions that can arise during run- time: exception condition trap flag trap vector vector location trap number trap priority reset functions: hardware reset software reset watchdog timer overflow reset reset reset 000000 h 000000 h 000000 h 00 h 00 h 00 h iii iii iii class a hardware traps: non-maskable interrupt stack overflow stack underflow nmi stkof stkuf nmitrap stotrap stutrap 000008 h 000010 h 000018 h 02 h 04 h 06 h ii ii ii class b hardware traps: undefined opcode protected instruction fault illegal word operand access illegal instruction access illegal external bus access undopc prtflt illopa illina illbus btrap btrap btrap btrap btrap 000028 h 000028 h 000028 h 000028 h 000028 h 0a h 0a h 0a h 0a h 0a h i i i i i reserved [2c h C 3c h ][0b h C 0f h ] software traps trap instruction any [000000 h C 0001fc h ] in steps of 4 h any [00 h C 7f h ] current cpu priority
semiconductor group 17 1998-02 c164ci 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 400 ns (at 20 mhz system clock). 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 occurence 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. compare modes function mode 0 interrupt-only compare mode; several compare interrupts per timer period are possible mode 1 pin toggles on each compare match; several compare events per timer period are possible mode 2 interrupt-only compare mode; only one compare interrupt per timer period is generated mode 3 pin set 1 on match; pin reset 0 on compare time overflow; only one compare event per timer period is generated double register mode two registers operate on one pin; pin toggles on each compare match; several compare events per timer period are possible. registers cc16 & cc24 t pin cc16io registers cc17 & cc25 t pin cc17io registers cc18 & cc26 t pin cc18io registers cc19 & cc27 t pin cc19io
semiconductor group 18 1998-02 c164ci 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. for motor control applications both subunits may generate versatile multichannel pwm signals which are basically either controlled by compare timer 12 or by a typical hall sensor pattern at the interrupt inputs (block commutation). compare timers 12 (16-bit) and 13 (10-bit) are free running timers which are clocked by the prescaled cpu clock. figure 5 capcom6 block diagram mcb03700 cc channel 0 cc60 cc61 cc channel 1 cc channel 2 cc62 control mode select register cc6msel t12p period register prescaler 16-bit compare timer t12 t12of offset register control register ctcon prescaler compare timer t13 10-bit t13p period register cmp13 compare register port control logic trap register control cc6m con.h commutation block ctrap cc60 cout60 cc61 cout61 cc62 cout62 cout63 cc6pos0 cc6pos1 cc6pos2 cpu f f cpu these registers are not direct accessable. the period and offset registers are loading a value into the timer registers. 1) 1) 1)
semiconductor group 19 1998-02 c164ci 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. timer t3 can be configured for one of four basic modes of operation, which are timer, gated timer, counter, and incremental interface mode. timers t2 and t4 can only be operated in timer 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 gate level on an external input pin. for these purposes the associated port pin (t3in) serves as gate or clock input. the maximum resolution of the timers is 400 ns (@ 20 mhz cpu clock). the count direction (up/down) for each timer is programmable by software or may additionally be altered dynamically by an external signal on pin t3eud for t3 to facilitate eg. position tracking. in incremental interface mode timer t3 can be directly connected to the incremental position sensor signals a and b via the respective inputs t3in and t3eud. direction and count signals are internally derived from these two input signals, so the contents of timer t3 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 registers for timer t3. when used as reload registers, timers t2 and t4 are stopped. timer t3 is reloaded with the contents of t2 or t4 triggered by a selectable state transition of its toggle latch t3otl.
semiconductor group 20 1998-02 c164ci figure 6 gpt block diagram 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 either by 2 or by 128. 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 25 m s and 420 ms can be monitored (@ 20 mhz). the default watchdog timer interval after reset is 6.55 ms (@ 20 mhz). x
semiconductor group 21 1998-02 c164ci real time clock the real time clock (rtc) module of the c164ci consists of a chain of 3 divider blocks, a fixed 8- bit 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 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: l system clock to determine the current time and date l cyclic time based interrupt l 48-bit timer for long term measurements figure 6-1 rtc block diagram note: the register associated with the rtc are not effected by a reset in order to maintain the correct system time even when intermediate resets are executed. rtcl rtcl t14 t14rel 8:1 f rtc reload interrupt request
semiconductor group 22 1998-02 c164ci 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 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 (eg. 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.
semiconductor group 23 1998-02 c164ci 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 siemens 8-bit microcontroller families and supports full-duplex asynchronous communication at up to 625 kbaud and half-duplex synchronous communication at up to 2.5 mbaud @ 20 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 5 mbaud @ 20 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.
semiconductor group 24 1998-02 c164ci 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), ie. the on-chip can- module 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 mbaud. the can-module uses two pins of port 4 to interface to a bus transceiver. note: when the can interface is to be used the segment address output on port 4 must be limited to 4 bits, ie. a19...a16. this is necessary to enable the alternate function of the can interface pins. parallel ports the c164ci provides up to 59 io 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 two io 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. all port lines have programmable alternate input or output functions associated with them. port0 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 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 and the system clock output (clkout). port 5 is used for the analog input channels to the a/d converter. all port lines that are not used for these alternate functions may be used as general purpose io lines.

semiconductor group 35 1998-02 c164ci notes 1) 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 results from the external circuitry. 2) the maximum current may be drawn while the respective signal line remains inactive. 3) the minimum current must be drawn in order to drive the respective signal line active. 4) this specification is only valid during reset, or during adapt-mode. 5) not 100% tested, guaranteed by design characterization. 6) the supply current is a function of the operating frequency. this dependency is illustrated in the figure below. these parameters are tested at v ddmax and 20 mhz cpu clock with all outputs disconnected and all inputs at v il or v ih . the oscillator also contributes to the total supply current. the given values refer to the worst case, i.e. i pdrmax . for lower oscillator frequencies the respective supply current can be reduced accordingly. 7) this parameter is tested including leakage currents. all inputs (including pins configured as inputs) at 0 v to 0.1 v or at v dd C 0.1 v to v dd , v ref = 0 v, all outputs (including pins configured as outputs) disconnected. 8) overload conditions under operating conditions occur if the voltage on the respective pin exceeds the specified operating range (i.e. v ov > v dd + 0.5 v or v ov < v ss C 0.5 v). the absolute sum of input overload currents on all port pins may not exceed 50 ma . the supply voltage ( v dd and v ss ) must remain within the specified limits. 9) this parameter is determined mainly by the current consumed by the oscillator. this current, however, is influenced by the external oscillator circuitry (crystal, capacitors). the values given refer to a typical circuitry and may change in case of a not optimized external oscillator circuitry. a typical value for i pdr at room temperature and f osc = 16 mhz is 300 m a. xtal1 input current i il cc C 20 m a0 v < v in < v dd pin capacitance 5) (digital inputs/outputs) c io cc C 10 pf f = 1 mhz t a = 25 c power supply current (active) with all peripherals active i dd C 10 + 3.5 f cpu ma rstin = v il2 f cpu in [mhz] 6) idle mode supply current with all peripherals active i idx C5 + 1.25 f cpu ma rstin = v ih1 f cpu in [mhz] 6) idle mode supply current with all peripherals deactivated, pll off, sdd factor = 32 i ido C 500 + 50 f osc 9) m a rstin = v ih1 f cpu in [mhz] 6) power-down mode supply current with rtc running i pdr C 100 + 25 f osc 9) m a v dd = 5.5 v f osc in [mhz] 7) power-down mode supply current with rtc disabled i pdo C50 m a v dd = 5.5 v 7) parameter symbol limit values unit test condition min. max.

semiconductor group 37 1998-02 c164ci ac characteristics definition of internal timing the internal operation of the c164ci is controlled by the internal cpu clock f cpu . both edges of the cpu clock can trigger internal (eg. pipeline) or external (eg. 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 below). figure 9 generation mechanisms for the cpu clock the cpu clock signal can be generated via different mechanisms. the duration of tcls and their variation (and also the derived external timing) depends on the used mechanism to generate f cpu . this influence must be regarded when calculating the timings for the c164ci. note: the example for pll operation shown in the figure above refers to a pll factor of 4. the used mechanism to generate the cpu clock is selected during reset via the logic levels on pins p0.15-13 (p0h.7-5). the table below associates the combinations of these three bits with the respective clock generation mode. tcl tcl tcl tcl f cpu f xtal f cpu f xtal phase locked loop operation direct clock drive tcl tcl f cpu f xtal prescaler operation
semiconductor group 38 1998-02 c164ci c164ci clock generation modes 1) the external clock input range refers to a cpu clock range of 10...20 mhz. 2) the maximum frequency depends on the duty cycle of the external clock signal. prescaler operation when pins p0.15-13 (p0h.7-5) equal 001 during reset the cpu clock is derived from the internal oscillator (input clock signal) by a 2:1 prescaler. the frequency of f cpu is half the frequency of f xtal and the high and low time of f cpu (ie. the duration of an individual tcl) is defined by the period of the input clock f xtal . the timings listed in the ac characteristics that refer to tcls therefore can be calculated using the period of f xtal for any tcl. direct drive when pins p0.15-13 (p0h.7-5) equal 011 during reset the on-chip phase locked loop is disabled and the cpu clock is directly driven from the internal oscillator with the input clock signal. the frequency of f cpu directly follows the frequency of f xtal so the high and low time of f cpu (ie. the duration of an individual tcl) is defined by the duty cycle of the input clock f xtal . 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 min = 1/f xtal * dc min (dc = duty cycle) for two consecutive tcls the deviation caused by the duty cycle of f xtal is compensated so the duration of 2tcl is always 1/f xtal . the minimum value tcl min therefore has to 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/f xtal . note: the address float timings in multiplexed bus mode (t 11 and t 45 ) use the maximum duration of tcl (tcl max = 1/f xtal * dc max ) instead of tcl min . p0.15-13 (p0h.7-5) cpu frequency f cpu = f xtal * f external clock input range 1) notes 111 f xtal * 4 2.5 to 5 mhz default configuration 110 f xtal * 3 3.33 to 6.66 mhz 101 f xtal * 2 5 to 10 mhz 100 f xtal * 5 2 to 4 mhz 011 f xtal * 1 1 to 20 mhz direct drive 2) 010 f xtal * 1.5 6.66 to 13.3 mhz 001 f xtal / 2 2 to 40 mhz cpu clock via prescaler 000 f xtal * 2.5 4 to 8 mhz
semiconductor group 39 1998-02 c164ci phase locked loop for all other combinations of pins p0.15-13 (p0h.7-5) during reset the on-chip phase locked loop is enabled and provides the cpu clock (see table above). the pll multiplies the input frequency by the factor f which is selected via the combination of pins p0.15-13 (ie. f cpu = f xtal * f ). with every f th transition of f xtal the pll circuit synchronizes the cpu clock to the input clock. this synchronization is done smoothely, ie. the cpu clock frequency does not change abruptly. due to this adaptation to the input clock the frequency of f cpu is constantly adjusted so it is locked to f xtal . the slight variation causes a jitter of f cpu 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 below). for a period of n * tcl the minimum value is computed using the corresponding deviation d n : tcl min = tcl nom * (1 - d n / 100) d n = (4 - n /15) [%], where n = number of consecutive tcls and 1 n 40. so for a period of 3 tcls (ie. n = 3): d 3 = 4 - 3 /15 = 3.8%, and (3tcl) min = 3tcl nom * (1 - 3.8 / 100) = 3tcl nom * 0.962 (57.72 nsec @ f cpu = 25 mhz). this is especially important for bus cycles using waitstates and eg. for the operation of timers, serial interfaces, etc. for all slower operations and longer periods (eg. pulse train generation or measurement, lower baudrates, etc.) the deviation caused by the pll jitter is neglectible. figure 10 approximated maximum pll jitter 32 16 8 4 2 1 2 3 4 max.jitter [%] n this approximated formula is valid for 1 n 40 and 10mhz f cpu 25mhz.

semiconductor group 42 1998-02 c164ci notes 1) v ain may exceed v agnd or v aref up to the absolute maximum ratings. however, the conversion result in these cases will be x000 h or x3ff h , respectively. 2) the limit values for f bc must not be exceeded when selecting the cpu frequency and the adctc setting. 3) this parameter includes the sample time t s , the time for determining the digital result and the time to load the result register with the conversion result. values for the basic clock t bc depend on programming and can be taken from the table above. this parameter depends on the adc control logic. it is not a real maximum value, but rather a fixum. 4) tue is tested at v aref =5.0v, v agnd =0v, v dd =4.9v. it is guaranteed by design for all other voltages within the defined voltage range. the specified tue is guaranteed only if an overload condition (see i ov specification) occurs on maximum 2 not selected analog input pins and the absolute sum of input overload currents on all analog input pins does not exceed 10 ma. during the reset calibration sequence the maximum tue may be 4 lsb. 5) during the conversion the adcs capacitance must be repeatedly charged or discharged. the internal resistance of the reference voltage source must allow the capacitance to reach its respective voltage level within each conversion step. the maximum internal resistance results from the programmed conversion timing. 6) not 100% tested, guaranteed by design. 7) during the sample time the input capacitance c i can be charged/discharged by the external source. the internal resistance of the analog source must allow the capacitance to reach its final voltage level within t s . after the end of the sample time t s , changes of the analog input voltage have no effect on the conversion result. values for the sample time t s depend on programming and can be taken from the table above.
