Input Outp. Function RSTIN I Reset Input with Schmitt-Trigger characteristics. A low level at this pin while the oscillator is running resets the XC164D. 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. 1 Note: The reset duration must be sufficient to let the hardware configuration signals settle. External circuitry must guarantee low level at the RSTIN pin at least until both power supply voltages have reached the operating range. P20.12 2 IO For details, please refer to the description of P20. NMI 3 I 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 XC164D 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.

Input Outp. Function P20 IO Port 20 is a 5-bit bidirectional I/O port. Each pin can be programmed for input (output driver in high-impedance state) or output. The input threshold of Port 20 is selectable (standard or special). The following Port 20 pins also serve for alternate functions: RD External Memory Read Strobe, activated for every external instruction or data read access. WR/WRL External Memory Write Strobe. In WR-mode this pin is activated for every external data write access. In WRL-mode this pin is activated for low byte data write accesses on a 16-bit bus, and for every data write access on an 8-bit bus. ALE Address Latch Enable Output. Can be used for latching the address into external memory or an address latch in the multiplexed bus modes. EA External Access Enable pin. A low level at this pin during and after Reset forces the XC164D to latch the configuration from PORT0 and pin RD, and to begin instruction execution out of external memory.

Data Sheet 17 V1.2, 2006-08 XC164D Derivatives Functional Description 3 Functional Description The architecture of the XC164D combines advantages of RISC, CISC, and DSP processors with an advanced peripheral subsystem in a very well-balanced way. In addition, the on-chip memory blocks allow the design of compact systems-on-silicon with maximum performance (computing, control, communication). The on-chip memory blocks (program code-memory and SRAM, dual-port RAM, data SRAM) and the set of generic peripherals are connected to the CPU via separate buses. Another bus, the LXBus, connects additional on-chip resources as well as external resources (see Figure 3). This bus structure enhances the overall system performance by enabling the concurrent operation of several subsystems of the XC164D. The following block diagram gives an overview of the different on-chip components and of the advanced, high bandwidth internal bus structure of the XC164D.

This common memory space includes 16 Mbytes and is arranged as 256 segments of 64 Kbytes each, where each segment consists of four data pages of 16 Kbytes each. The entire memory space can be accessed bytewise or wordwise. Portions of the on-chip DPRAM and the register spaces (E/SFR) have additionally been made directly bitaddressable. 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 accesses to the program memories, such as Flash memory, and PSRAM. The Data Management Unit (DMU) handles all data transfers and, therefore, controls accesses to the DSRAM and the on-chip peripherals. Both units (PMU and DMU) are connected via the high-speed system bus to 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, including peripherals on the LXBus (such as TwinCAN). The system bus allows concurrent two-way communication for maximum transfer performance. 64/128 Kbytes1) of on-chip Flash memory or mask-programmable ROM store code or constant data. The on-chip Flash memory is organized as four 8-Kbyte sectors, one 32-Kbyte sector, and one 64-Kbyte sector. Each sector can be separately write protected2), erased and programmed (in blocks of 128 Bytes). The complete Flash or ROM area can be read-protected. A password sequence temporarily unlocks protected areas. The Flash module combines very fast 64-bit one-cycle read accesses with protected and efficient writing algorithms for programming and erasing. Thus, program execution out of the internal Flash results in maximum performance. Dynamic error correction provides extremely high read data security for all read accesses. For timing characteristics, please refer to Section 4.3.2. 2 Kbytes of on-chip Program SRAM (PSRAM) are provided to store user code or data. The PSRAM is accessed via the PMU and is therefore optimized for code fetches. 2/4 Kbytes1) of on-chip Data SRAM (DSRAM) are provided as a storage for general user data. The DSRAM is accessed via the DMU and is therefore optimized for data accesses. 2 Kbytes of on-chip Dual-Port RAM (DPRAM) are provided as a storage for user defined variables, for the system stack, and general purpose register banks. A register 1) Depends on the respective derivative. The derivatives are listed in Table 1. 2) Each two 8-Kbyte sectors are combined for write-protection purposes. Data Sheet 19 V1.2, 2006-08 XC164D Derivatives Functional Description bank can consist of up to 16 wordwide (R0 to R15) and/or bytewide (RL0, RH0, …, RL7, RH7) so-called General Purpose Registers (GPRs). The upper 256 bytes of the DPRAM are directly bitaddressable. When used by a GPR, any location in the DPRAM is bitaddressable. 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 XC166 Family. Therefore, they should either not be accessed, or written with zeros, to ensure upward compatibility. In order to meet the needs of designs where more memory is required than is provided on chip, up to 12 Mbytes (approximately, see Table 3) of external RAM and/or ROM can be connected to the microcontroller.

Alarm interrupt for wake-up on a defined time. Data Sheet 38 V1.2, 2006-08 XC164D Derivatives Functional Description 3.10 Asynchronous/Synchronous Serial Interfaces (ASC0/ASC1) The Asynchronous/Synchronous Serial Interfaces ASC0/ASC1 (USARTs) provide serial communication with other microcontrollers, processors, terminals or external peripheral components. They are upward compatible with the serial ports of the Infineon 8-bit microcontroller families and support full-duplex asynchronous communication and halfduplex synchronous communication. A dedicated baud rate generator with a fractional divider precisely generates all standard baud rates without oscillator tuning. For transmission, reception, error handling, and baudrate detection 5 separate interrupt vectors are provided. In asynchronous mode, 8- or 9-bit data frames (with optional parity bit) 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). IrDA data transmissions up to 115.2 kbit/s with fixed or programmable IrDA pulse width are supported. In synchronous mode, bytes (8 bits) are transmitted or received synchronously to a shift clock which is generated by the ASC0/1. The LSB is always shifted first. In both modes, transmission and reception of data is FIFO-buffered. An autobaud detection unit allows to detect asynchronous data frames with its baudrate and mode with automatic initialization of the baudrate generator and the mode control bits. 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. Summary of Features • • • • • Full-duplex asynchronous operating modes – 8- or 9-bit data frames, LSB first, one or two stop bits, parity generation/checking – Baudrate from 2.5 Mbit/s to 0.6 bit/s (@ 40 MHz) – Multiprocessor mode for automatic address/data byte detection – Support for IrDA data transmission/reception up to max. 115.2 kbit/s (@ 40 MHz) – Loop-back capability – Auto baudrate detection Half-duplex 8-bit synchronous operating mode at 5 Mbit/s to 406.9 bit/s (@ 40 MHz) Buffered transmitter/receiver with FIFO support (8 entries per direction) Loop-back option available for testing purposes Interrupt generation on transmitter buffer empty condition, last bit transmitted condition, receive buffer full condition, error condition (frame, parity, overrun error), start and end of an autobaud detection Data Sheet 39 V1.2, 2006-08 XC164D Derivatives Functional Description 3.11 High Speed Synchronous Serial Channels (SSC0/SSC1) The High Speed Synchronous Serial Channels SSC0/SSC1 support full-duplex and halfduplex synchronous communication. It may be configured so it interfaces with serially linked peripheral components, full SPI functionality is supported. A dedicated baud rate generator allows to set up all standard baud rates without oscillator tuning. For transmission, reception and error handling three 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 error and receive error supervise the correct handling of the data buffer. Phase error and baudrate error detect incorrect serial data.

Two Full-CAN nodes share the TwinCAN module’s resources to optimize the CAN bus traffic handling and to minimize the CPU load. The module provides up to 32 message objects, which can be assigned to one of the CAN nodes and can be combined to FIFOstructures. Each object provides separate masks for acceptance filtering. The flexible combination of Full-CAN functionality and FIFO architecture reduces the efforts to fulfill the real-time requirements of complex embedded control applications. Improved CAN bus monitoring functionality as well as the number of message objects permit precise and comfortable CAN bus traffic handling. Gateway functionality allows automatic data exchange between two separate CAN bus systems, which reduces CPU load and improves the real time behavior of the entire system. The bit timing for both CAN nodes is derived from the master clock and is programmable up to a data rate of 1 Mbit/s. Each CAN node uses two pins of Port 4 or Port 9 to interface to an external bus transceiver. The interface pins are assigned via software.

CS lines can be used to increase the total amount of addressable external memory. Data Sheet 42 V1.2, 2006-08 XC164D Derivatives Functional Description 3.13 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 be disabled until the EINIT instruction has been executed (compatible mode), or it can be disabled and enabled at any time by executing instructions DISWDT and ENWDT (enhanced mode). Thus, the chip’s start-up procedure is always monitored. The software has to be designed to restart 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 and the low byte is cleared. Thus, time intervals between 13 µs and 419 ms can be monitored (@ 40 MHz). The default Watchdog Timer interval after reset is 3.28 ms (@ 40 MHz). Data Sheet 43 V1.2, 2006-08 XC164D Derivatives Functional Description 3.14 Clock Generation The Clock Generation Unit uses a programmable on-chip PLL with multiple prescalers to generate the clock signals for the XC164D with high flexibility. The master clock fMC is the reference clock signal, and is used for TwinCAN and is output to the external system. The CPU clock fCPU and the system clock fSYS are derived from the master clock either directly (1:1) or via a 2:1 prescaler (fSYS = fCPU = fMC / 2). See also Section 4.3.1. The on-chip oscillator can drive an external crystal or accepts an external clock signal. The oscillator clock frequency can be multiplied by the on-chip PLL (by a programmable factor) or can be divided by a programmable prescaler factor. If the bypass mode is used (direct drive or prescaler) the PLL can deliver an independent clock to monitor the clock signal generated by the on-chip oscillator. This PLL clock is independent from the XTAL1 clock. When the expected oscillator clock transitions are missing the Oscillator Watchdog (OWD) activates the PLL Unlock/OWD interrupt node and supplies the CPU with an emergency clock, the PLL clock signal. Under these circumstances the PLL will oscillate with its basic frequency. The oscillator watchdog can be disabled by switching the PLL off. This reduces power consumption, but also no interrupt request will be generated in case of a missing oscillator clock. Note: At the end of an external reset (EA = ‘0’) the oscillator watchdog may be disabled via hardware by (externally) pulling the RD line low upon a reset, similar to the standard reset configuration. 3.15 Parallel Ports The XC164D provides up to 79 I/O lines which are organized into six 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 some 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 (except for pin RSTOUT). The edge characteristics (shape) and driver characteristics (output current) of the port drivers can be selected via registers POCONx. The input threshold of some ports 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.

Data Sheet 45 V1.2, 2006-08 XC164D Derivatives Functional Description 3.16 Power Management The XC164D 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 XC164D 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. While the clock signals for currently inactive parts of logic are disabled automatically, the user can reduce the XC164D’s CPU clock frequency which drastically reduces the consumed power. 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. The on-chip RTC supports intermittent operation of the XC164D by generating cyclic wake-up signals. This offers full performance to quickly react on action requests while the intermittent sleep phases greatly reduce the average power consumption of the system. Data Sheet 46 V1.2, 2006-08 XC164D Derivatives Functional Description 3.17 Instruction Set Summary Table 8 lists the instructions of the XC164D in a condensed way.

During absolute maximum rating overload conditions (VIN > VDDP or VIN < VSS) the voltage on VDDP pins with respect to ground (VSS) must not exceed the values defined by the absolute maximum ratings.

The range limits may be reached under extreme operating conditions. However, specified parameters, such as leakage currents, refer to the standard operating voltage range of VDDP = 4.75 V to 5.25 V. 4) This limitation must be fulfilled under all operating conditions including power-ramp-up, power-ramp-down, and power-save modes. Data Sheet 51 V1.2, 2006-08 XC164D Derivatives Electrical Parameters 5) Overload conditions occur if the standard operating conditions are exceeded, i.e. the voltage on any pin exceeds the specified range: VOV > VDDP + 0.5 V (IOV > 0) or VOV < VSS - 0.5 V (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 is not guaranteed if overload conditions occur on functional pins such as XTAL1, RD, WR, etc. 6) Not subject to production test - verified by design/characterization. 7) An overload current (IOV) through a pin injects a certain error current (IINJ) into the adjacent pins. This error current adds to the respective pin’s leakage current (IOZ). The amount of error current depends on the overload current and is defined by the overload coupling factor KOV. The polarity of the injected error current is inverse compared to the polarity of the overload current that produces it. The total current through a pin is |ITOT| = |IOZ| + (|IOV| × KOV). 8) 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). Parameter Interpretation The parameters listed in the following partly represent the characteristics of the XC164D and partly its demands on the system. To aid in interpreting the parameters right, when evaluating them for a design, they are marked in column “Symbol”: CC (Controller Characteristics): The logic of the XC164D will provide signals with the respective characteristics. SR (System Requirement): The external system must provide signals with the respective characteristics to the XC164D.

The limit for pin groups must be respected. 5) 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 guaranteed. 6) 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. 7) 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. 8) The driver of P3.15 is designed for faster switching, because this pin can deliver the reference clock for the bus interface (CLKOUT). The maximum leakage current for P3.15 is, therefore, increased to 1 µA. 9) This specification is valid during Reset for configuration on RD, WR, EA, PORT0 10) The maximum current may be drawn while the respective signal line remains inactive. 11) The minimum current must be drawn to drive the respective signal line active. 12) This specification is valid during Reset for configuration on ALE. 13) This specification is valid during Reset for pins P4.3-0, which can act as CS outputs, and for P3.12. 14) Not subject to production test - verified by design/characterization.

This dependency is illustrated in Figure 11. These parameters are tested at VDDImax and maximum CPU clock frequency with all outputs disconnected and all inputs at VIL or VIH. 3) The pad supply voltage pins (VDDP) mainly provides the current consumed by the pin output drivers. A small amount of current is consumed even though no outputs are driven, because the drivers’ input stages are switched and also the Flash module draws some power from the VDDP supply. 4) The total supply current in Sleep and Power down mode is the sum of the temperature dependent leakage current and the frequency dependent current for RTC and main oscillator (if active). 5) This parameter is determined mainly by the transistor leakage currents. This current heavily depends on the junction temperature (see Figure 13). The junction temperature TJ is the same as the ambient temperature TA if no current flows through the port output drivers. Otherwise, the resulting temperature difference must be taken into account. 6) All inputs (including pins configured as inputs) at 0 V to 0.1 V or at VDDP - 0.1 V to VDDP, all outputs (including pins configured as outputs) disconnected. This parameter is tested at 25 °C and is valid for TJ ≥ 25 °C. 7) This parameter is determined mainly by the current consumed by the oscillator switched to low gain mode (see Figure 12). This current, however, is influenced by the external oscillator circuitry (crystal, capacitors). The given values refer to a typical circuitry and may change in case of a not optimized external oscillator circuitry.

The master clock signal fMC can be generated from the oscillator clock signal fOSC via different mechanisms. The duration of master clock periods (TCMs) and their variation (and also the derived external timing) depend on the used mechanism to generate fMC. This influence must be regarded when calculating the timings for the XC164D. Phase Locked Loop Operation (1:N) f OSC f MC TCM Direct Clock Drive (1:1) f OSC f MC TCM Prescaler Operation (N:1) f OSC f MC TCM MCT05555 Figure 14 Generation Mechanisms for the Master Clock Note: The example for PLL operation shown in Figure 14 refers to a PLL factor of 1:4, the example for prescaler operation refers to a divider factor of 2:1. The used mechanism to generate the master clock is selected by register PLLCON. Data Sheet 58 V1.2, 2006-08 XC164D Derivatives Electrical Parameters CPU and EBC are clocked with the CPU clock signal fCPU. The CPU clock can have the same frequency as the master clock (fCPU = fMC) or can be the master clock divided by two: fCPU = fMC / 2. This factor is selected by bit CPSYS in register SYSCON1. The specification of the external timing (AC Characteristics) depends on the period of the CPU clock, called “TCP”. The other peripherals are supplied with the system clock signal fSYS which has the same frequency as the CPU clock signal fCPU. Bypass Operation When bypass operation is configured (PLLCTRL = 0xB) the master clock is derived from the internal oscillator (input clock signal XTAL1) through the input- and outputprescalers: fMC = fOSC / ((PLLIDIV+1) × (PLLODIV+1)). If both divider factors are selected as ‘1’ (PLLIDIV = PLLODIV = ‘0’) the frequency of fMC directly follows the frequency of fOSC so the high and low time of fMC is defined by the duty cycle of the input clock fOSC. The lowest master clock frequency is achieved by selecting the maximum values for both divider factors: fMC = fOSC / ((3 + 1) × (14 + 1)) = fOSC / 60. Phase Locked Loop (PLL) When PLL operation is configured (PLLCTRL = 11B) the on-chip phase locked loop is enabled and provides the master clock. The PLL multiplies the input frequency by the factor F (fMC = fOSC × F) which results from the input divider, the multiplication factor, and the output divider (F = PLLMUL+1 / (PLLIDIV+1 × PLLODIV+1)). The PLL circuit synchronizes the master clock to the input clock. This synchronization is done smoothly, i.e. the master clock frequency does not change abruptly. Due to this adaptation to the input clock the frequency of fMC is constantly adjusted so it is locked to fOSC. The slight variation causes a jitter of fMC which also affects the duration of individual TCMs. The timing listed in the AC Characteristics refers to TCPs. Because fCPU is derived from fMC, the timing must be calculated using the minimum TCP possible under the respective circumstances. The actual minimum value for TCP 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 TCP is lower than for one single TCP (see formula and Figure 15). 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 Data Sheet 59 V1.2, 2006-08 XC164D Derivatives Electrical Parameters 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 (K = PLLODIV+1) to generate the master clock signal fMC. Therefore, the number of VCO cycles can be represented as K × N, where N is the number of consecutive fMC cycles (TCM). For a period of N × TCM the accumulated PLL jitter is defined by the deviation DN: DN [ns] = ±(1.5 + 6.32 × N / fMC); fMC in [MHz], N = number of consecutive TCMs. So, for a period of 3 TCMs @ 20 MHz and K = 12: D3 = ±(1.5 + 6.32 × 3 / 20) = 2.448 ns. This formula is applicable for K × N < 95. For longer periods the K × N = 95 value can be used. This steady value can be approximated by: DNmax [ns] = ±(1.5 + 600 / (K × fMC)).

Different frequency bands can be selected for the VCO, so the operation of the PLL can be adjusted to a wide range of input and output frequencies: Data Sheet 60 V1.2, 2006-08 XC164D Derivatives Electrical Parameters Table 14 VCO Bands for PLL Operation1) PLLCON.PLLVB VCO Frequency Range Base Frequency Range 00 100 … 150 MHz 20 … 80 MHz 01 150 … 200 MHz 40 … 130 MHz 10 200 … 250 MHz 60 … 180 MHz 11 Reserved 1) Not subject to production test - verified by design/characterization. Data Sheet 61 V1.2, 2006-08 XC164D Derivatives Electrical Parameters 4.3.2 On-chip Flash Operation The XC164D’s Flash module delivers data within a fixed access time (see Table 15). Accesses to the Flash module are controlled by the PMI and take 1+WS clock cycles, where WS is the number of Flash access waitstates selected via bitfield WSFLASH in register IMBCTRL. The resulting duration of the access phase must cover the access time tACC of the Flash array. Therefore, the required Flash waitstates depend on the available speed grade as well as on the actual system frequency. Note: The Flash access waitstates only affect non-sequential accesses. Due to prefetching mechanisms, the performance for sequential accesses (depending on the software structure) is only partially influenced by waitstates. In typical applications, eliminating one waitstate increases the average performance by 5% … 15%.

Example: For an operating frequency of 40 MHz (clock cycle = 25 ns), devices can be operated with 1 waitstate: ((1+1) × 25 ns) ≥ 50 ns. Table 16 indicates the interrelation of waitstates and system frequency.

Please refer to the limits specified by the crystal supplier. When driven by an external clock signal it will accept the specified frequency range.
