On-chip memory blocks allow the design of compact systems-on-silicon with maximum performance suited for computing, control, and communication. The on-chip memory blocks (program code memory and SRAM, dual-port RAM, data SRAM) and the generic peripherals are connected to the CPU by separate high-speed buses. Another bus, the LXBus, connects additional on-chip resources and external resources (see Figure 4). This bus structure enhances overall system performance by enabling the concurrent operation of several subsystems of the XC223xN. The block diagram gives an overview of the on-chip components and the advanced internal bus structure of the XC223xN.

End Loc. Area Size2) Reserved for DSRAM 00'8000H 00'9FFFH 8 Kbytes External memory area 00'0000H 00'7FFFH 32 Kbytes Notes 1) Accesses to the shaded areas are reserved. In devices with external bus interface these accesses generate external bus accesses. 2) The areas marked with "<" are slightly smaller than indicated, see column "Notes". 3) The uppermost 4-Kbyte sector of the first Flash segment is reserved for internal use (C0'F000H to C0'FFFFH). 4) Several pipeline optimizations are not active within the external IO area. This is necessary to control external peripherals properly. This common memory space consists of 16 Mbytes organized as 256 segments of 64 Kbytes; each segment contains four data pages of 16 Kbytes. The entire memory space can be accessed bytewise or wordwise. Portions of the on-chip DPRAM and the register spaces (ESFR/SFR) additionally are directly bit addressable. The internal data memory areas and the Special Function Register areas (SFR and ESFR) are mapped into segment 0, the system segment. The Program Management Unit (PMU) handles all code fetches and, therefore, controls access to the program memories such as Flash memory and PSRAM. The Data Management Unit (DMU) handles all data transfers and, therefore, controls access to the DSRAM and the on-chip peripherals. Both units (PMU and DMU) are connected to the high-speed system bus so that they can exchange data. This is required if operands are read from program memory, code or data is written to the PSRAM, code is fetched from external memory, or data is read from or written to external resources. These include peripherals on the LXBus such as USIC or MultiCAN. The system bus allows concurrent two-way communication for maximum transfer performance. Up to 16 Kbytes of on-chip Program SRAM (PSRAM) are provided to store user code or data. The PSRAM is accessed via the PMU and is optimized for code fetches. A section of the PSRAM with programmable size can be write-protected. Note: The actual size of the PSRAM depends on the quoted device type. Data Sheet 30 V1.2, 2009-12 XC2232N, XC2234N, XC2236N, XC2238N XC2000 Family / Value Line Functional Description Up to 16 Kbytes of on-chip Data SRAM (DSRAM) are used for storage of general user data. The DSRAM is accessed via a separate interface and is optimized for data access. Note: The actual size of the DSRAM depends on the quoted device type. 2 Kbytes of on-chip Dual-Port RAM (DPRAM) provide storage for user-defined variables, for the system stack, and for general purpose register banks. A register bank can consist of up to 16 word-wide (R0 to R15) and/or byte-wide (RL0, RH0, ..., RL7, RH7) General Purpose Registers (GPRs). The upper 256 bytes of the DPRAM are directly bit addressable. When used by a GPR, any location in the DPRAM is bit addressable. 8 Kbytes of on-chip Stand-By SRAM (SBRAM) provide storage for system-relevant user data that must be preserved while the major part of the device is powered down. The SBRAM is accessed via a specific interface and is powered in domain M. 1024 bytes (2 x 512 bytes) of the address space are reserved for the Special Function Register areas (SFR space and ESFR space). SFRs are word-wide registers which are used to control and monitor functions of the different on-chip units. Unused SFR addresses are reserved for future members of the XC2000 Family. In order to ensure upward compatibility they should either not be accessed or written with zeros. In order to meet the requirements of designs where more memory is required than is available on chip, up to 12 Mbytes (approximately, see Table 8) of external RAM and/or ROM can be connected to the microcontroller. The External Bus Interface also provides access to external peripherals. The on-chip Flash memory stores code, constant data, and control data. The 320 Kbytes of on-chip Flash memory consist of 1 module of 64 Kbytes (preferably for data storage) and 1 module of 256 Kbytes. Each module is organized in 4-Kbyte sectors. The uppermost 4-Kbyte sector of segment 0 (located in Flash module 0) is used internally to store operation control parameters and protection information. Note: The actual size of the Flash memory depends on the chosen device type. Each sector can be separately write protected1), erased and programmed (in blocks of 128 Bytes). The complete Flash area can be read-protected. A user-defined password sequence temporarily unlocks protected areas. The Flash modules combine 128-bit read access with protected and efficient writing algorithms for programming and erasing. Dynamic error correction provides extremely high read data security for all read access operations. Access to different Flash modules can be executed in parallel. For Flash parameters, please see Section 4.6. 1) To save control bits, sectors are clustered for protection purposes, they remain separate for programming/erasing. Data Sheet 31 V1.2, 2009-12 XC2232N, XC2234N, XC2236N, XC2238N XC2000 Family / Value Line Functional Description Memory Content Protection The contents of on-chip memories can be protected against soft errors (induced e.g. by radiation) by activating the parity mechanism or the Error Correction Code (ECC). The parity mechanism can detect a single-bit error and prevent the software from using incorrect data or executing incorrect instructions. The ECC mechanism can detect and automatically correct single-bit errors. This supports the stable operation of the system. It is strongly recommended to activate the ECC mechanism wherever possible because this dramatically increases the robustness of an application against such soft errors. Data Sheet 32 V1.2, 2009-12 XC2232N, XC2234N, XC2236N, XC2238N XC2000 Family / Value Line Functional Description 3.2 Central Processing Unit (CPU) The core of the CPU consists of a 5-stage execution pipeline with a 2-stage instructionfetch pipeline, a 16-bit arithmetic and logic unit (ALU), a 32-bit/40-bit multiply and accumulate unit (MAC), a register-file providing three register banks, and dedicated SFRs. The ALU features a multiply-and-divide unit, a bit-mask generator, and a barrel shifter.

For example, shift and rotate instructions are always processed during one machine cycle, no matter how many bits are shifted. Also, multiplication and most MAC instructions execute in one cycle. All multiple-cycle instructions have been optimized so that they can be executed very fast; for example, a 32-/16-bit division is started within 4 cycles while the remaining cycles are executed in the background. Another pipeline optimization, the branch target prediction, eliminates the execution time of branch instructions if the prediction was correct. The CPU has a register context consisting of up to three register banks with 16 wordwide GPRs each at its disposal. One of these register banks is physically allocated within the on-chip DPRAM area. A Context Pointer (CP) register determines the base address of the active register bank accessed by the CPU at any time. The number of these register bank copies is only restricted by the available internal RAM space. For easy parameter passing, a register bank may overlap others. A system stack of up to 32 Kwords is provided for storage of temporary data. The system stack can be allocated to any location within the address space (preferably in the on-chip RAM area); it is accessed by the CPU with the stack pointer (SP) register. Two separate SFRs, STKOV and STKUN, are implicitly compared with the stack pointer value during each stack access to detect stack overflow or underflow. The high performance of the CPU hardware implementation can be best utilized by the programmer with the highly efficient XC223xN instruction set. This includes the following instruction classes: * * * * * * * * * * * * * Standard Arithmetic Instructions DSP-Oriented Arithmetic Instructions Logical Instructions Boolean Bit Manipulation Instructions Compare and Loop Control Instructions Shift and Rotate Instructions Prioritize Instruction Data Movement Instructions System Stack Instructions Jump and Call Instructions Return Instructions System Control Instructions Miscellaneous Instructions The basic instruction length is either 2 or 4 bytes. Possible operand types are bits, bytes and words. A variety of direct, indirect or immediate addressing modes are provided to specify the required operands. Data Sheet 34 V1.2, 2009-12 XC2232N, XC2234N, XC2236N, XC2238N XC2000 Family / Value Line Functional Description 3.3 Memory Protection Unit (MPU) The XC223xN's Memory Protection Unit (MPU) protects user-specified memory areas from unauthorized read, write, or instruction fetch accesses. The MPU can protect the whole address space including the peripheral area. This completes established mechanisms such as the register security mechanism or stack overrun/underrun detection. Four Protection Levels support flexible system programming where operating system, low level drivers, and applications run on separate levels. Each protection level permits different access restrictions for instructions and/or data. Every access is checked (if the MPU is enabled) and an access violating the permission rules will be marked as invalid and leads to a protection trap. A set of protection registers for each protection level specifies the address ranges and the access permissions. Applications requiring more than 4 protection levels can dynamically re-program the protection registers. 3.4 Memory Checker Module (MCHK) The XC223xN's Memory Checker Module calculates a checksum (fractional polynomial division) on a block of data, often called Cyclic Redundancy Code (CRC). It is based on a 32-bit linear feedback shift register and may, therefore, also be used to generate pseudo-random numbers. The Memory Checker Module is a 16-bit parallel input signature compression circuitry which enables error detection within a block of data stored in memory, registers, or communicated e.g. via serial communication lines. It reduces the probability of error masking due to repeated error patterns by calculating the signature of blocks of data. The polynomial used for operation is configurable, so most of the commonly used polynomials may be used. Also, the block size for generating a CRC result is configurable via a local counter. An interrupt may be generated if testing the current data block reveals an error. An autonomous CRC compare circuitry is included to enable redundant error detection, e.g. to enable higher safety integrity levels. The Memory Checker Module provides enhanced fault detection (beyond parity or ECC) for data and instructions in volatile and non volatile memories. This is especially important for the safety and reliability of embedded systems. Data Sheet 35 V1.2, 2009-12 XC2232N, XC2234N, XC2236N, XC2238N XC2000 Family / Value Line Functional Description 3.5 Interrupt System The architecture of the XC223xN supports several mechanisms for fast and flexible response to service requests; these can be generated from various sources internal or external to the microcontroller. Any of these interrupt requests can be programmed to be serviced by the Interrupt Controller or by the Peripheral Event Controller (PEC). Using a standard interrupt service the current program execution is suspended and a branch to the interrupt vector table is performed. With the PEC just one cycle is `stolen' from the current CPU activity to perform the PEC service. A PEC service implies a single byte or word data transfer between any two memory locations with an additional increment of either the PEC source pointer, the destination pointer, or both. An individual PEC transfer counter is implicitly decremented for each PEC service except when performing in the continuous transfer mode. When this counter reaches zero, a standard interrupt is performed to the corresponding source-related vector location. PEC services are particularly well suited to supporting the transmission or reception of blocks of data. The XC223xN has eight PEC channels, each with fast interrupt-driven data transfer capabilities. With a minimum interrupt response time of 7/111) CPU clocks, the XC223xN can react quickly to the occurrence of non-deterministic events. Interrupt Nodes and Source Selection The interrupt system provides 96 physical nodes with separate control register containing an interrupt request flag, an interrupt enable flag and an interrupt priority bit field. Most interrupt sources are assigned to a dedicated node. A particular subset of interrupt sources shares a set of nodes. The source selection can be programmed using the interrupt source selection (ISSR) registers. External Request Unit (ERU) A dedicated External Request Unit (ERU) is provided to route and preprocess selected on-chip peripheral and external interrupt requests. The ERU features 4 programmable input channels with event trigger logic (ETL) a routing matrix and 4 output gating units (OGU). The ETL features rising edge, falling edge, or both edges event detection. The OGU combines the detected interrupt events and provides filtering capabilities depending on a programmable pattern match or miss. Trap Processing The XC223xN provides efficient mechanisms to identify and process exceptions or error conditions that arise during run-time, the so-called `Hardware Traps'. A hardware trap causes an immediate system reaction similar to a standard interrupt service (branching 1) Depending if the jump cache is used or not. Data Sheet 36 V1.2, 2009-12 XC2232N, XC2234N, XC2236N, XC2238N XC2000 Family / Value Line Functional Description to a dedicated vector table location). The occurrence of a hardware trap is also indicated by a single bit in the trap flag register (TFR). Unless another higher-priority trap service is in progress, a hardware trap will interrupt any ongoing program execution. In turn, hardware trap services can normally not be interrupted by standard or PEC interrupts. Depending on the package option up to 3 External Service Request (ESR) pins are provided. The ESR unit processes their input values and allows to implement user controlled trap functions (System Requests SR0 and SR1). In this way reset, wakeup and power control can be efficiently realized. Software interrupts are supported by the `TRAP' instruction in combination with an individual trap (interrupt) number. Alternatively to emulate an interrupt by software a program can trigger interrupt requests by writing the Interrupt Request (IR) bit of an interrupt control register. 3.6 On-Chip Debug Support (OCDS) The On-Chip Debug Support system built into the XC223xN provides a broad range of debug and emulation features. User software running on the XC223xN can be debugged within the target system environment. The OCDS is controlled by an external debugging device via the debug interface. This either consists of the 2-pin Device Access Port (DAP) or of the JTAG port conforming to IEEE-1149. The debug interface can be completed with an optional break interface. The debugger controls the OCDS with a set of dedicated registers accessible via the debug interface (DAP or JTAG). In addition the OCDS system can be controlled by the CPU, e.g. by a monitor program. An injection interface allows the execution of OCDSgenerated instructions by the CPU. Multiple breakpoints can be triggered by on-chip hardware, by software, or by an external trigger input. Single stepping is supported, as is the injection of arbitrary instructions and read/write access to the complete internal address space. A breakpoint trigger can be answered with a CPU halt, a monitor call, a data transfer, or/and the activation of an external signal. Tracing of data can be obtained via the debug interface, or via the external bus interface for increased performance. Tracing of program execution is supported by the XC2000 Family emulation device. With this device the DAP can operate on clock rates of up to 20 MHz. The DAP interface uses two interface signals, the JTAG interface uses four interface signals, to communicate with external circuitry. The debug interface can be amended with two optional break lines. Data Sheet 37 V1.2, 2009-12 XC2232N, XC2234N, XC2236N, XC2238N XC2000 Family / Value Line Functional Description 3.7 Capture/Compare Unit (CC2) The CAPCOM unit supports generation and control of timing sequences on up to 16 channels with a maximum resolution of one system clock cycle (eight cycles in staggered mode). The CAPCOM unit is typically used to handle high-speed I/O tasks such as pulse and waveform generation, pulse width modulation (PWM), digital to analog (D/A) conversion, software timing, or time recording with respect to external events. Two 16-bit timers with reload registers provide two independent time bases for the capture/compare register array. The input clock for the timers is programmable to several prescaled values of the internal system clock, or may be derived from an overflow/underflow of timer T6 in module GPT2. This provides a wide range of variation for the timer period and resolution and allows precise adjustments to the application specific requirements. In addition, external count inputs allow event scheduling for the capture/compare registers relative to external events. The capture/compare register array contains 16 dual purpose capture/compare registers, each of which may be individually allocated to either CAPCOM timer and programmed for capture or compare function. All registers have each one port pin associated with it which serves as an input pin for triggering the capture function, or as an output pin to indicate the occurrence of a compare event. When a capture/compare register has been selected for capture mode, the current contents of the allocated timer will be latched (`captured') into the capture/compare register in response to an external event at the port pin which is associated with this register. In addition, a specific interrupt request for this capture/compare register is generated. Either a positive, a negative, or both a positive and a negative external signal transition at the pin can be selected as the triggering event. The contents of all registers which have been selected for one of the five compare modes are continuously compared with the contents of the allocated timers. When a match occurs between the timer value and the value in a capture/compare register, specific actions will be taken based on the selected compare mode. Table 9 Compare Modes 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 Data Sheet 38 V1.2, 2009-12 XC2232N, XC2234N, XC2236N, XC2238N XC2000 Family / Value Line Functional Description Table 9 Compare Modes (cont'd) Compare Modes Function 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 timer 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 Single Event Mode Generates single edges or pulses; Can be used with any compare mode When a capture/compare register has been selected for capture mode, the current contents of the allocated timer will be latched (`captured') into the capture/compare register in response to an external event at the port pin associated with this register. In addition, a specific interrupt request for this capture/compare register is generated. Either a positive, a negative, or both a positive and a negative external signal transition at the pin can be selected as the triggering event. The contents of all registers selected for one of the five compare modes are continuously compared with the contents of the allocated timers. When a match occurs between the timer value and the value in a capture/compare register, specific actions will be taken based on the compare mode selected.

CCU6 is a high-resolution capture and compare unit with application-specific modes. It provides inputs to start the timers synchronously, an important feature in devices with several CCU6 modules. The module provides two independent timers (T12, T13), that can be used for PWM generation, especially for AC motor control. Additionally, special control modes for block commutation and multi-phase machines are supported. Timer 12 Features * * * * * * * * * * Three capture/compare channels, where each channel can be used either as a capture or as a compare channel.

The modulation sources can be selected and combined for signal modulation. Data Sheet 42 V1.2, 2009-12 XC2232N, XC2234N, XC2236N, XC2238N XC2000 Family / Value Line Functional Description 3.9 General Purpose Timer (GPT12E) Unit The GPT12E unit is a very flexible multifunctional timer/counter structure which can be used for many different timing tasks such as event timing and counting, pulse width and duty cycle measurements, pulse generation, or pulse multiplication. The GPT12E unit incorporates five 16-bit timers organized in two separate modules, GPT1 and GPT2. Each timer in each module may either operate independently in a number of different modes or be concatenated with another timer of the same module. Each of the three timers T2, T3, T4 of module GPT1 can be configured individually for one of four basic modes of operation: Timer, Gated Timer, Counter, and Incremental Interface Mode. In Timer Mode, the input clock for a timer is derived from the system clock and divided by a programmable prescaler. Counter Mode allows timer clocking in reference to external events. Pulse width or duty cycle measurement is supported in Gated Timer Mode, where the operation of a timer is controlled by the `gate' level on an external input pin. For these purposes each timer has one associated port pin (TxIN) which serves as a gate or clock input. The maximum resolution of the timers in module GPT1 is 4 system clock cycles. The counting direction (up/down) for each timer can be programmed by software or altered dynamically by an external signal on a port pin (TxEUD), e.g. to facilitate position tracking. In Incremental Interface Mode the GPT1 timers can be directly connected to the incremental position sensor signals A and B through their respective inputs TxIN and TxEUD. Direction and counting signals are internally derived from these two input signals, so that the contents of the respective timer Tx corresponds to the sensor position. The third position sensor signal TOP0 can be connected to an interrupt input. Timer T3 has an output toggle latch (T3OTL) which changes its state on each timer overflow/underflow. The state of this latch may be output on pin T3OUT e.g. for time out monitoring of external hardware components. It may also be used internally to clock timers T2 and T4 for measuring long time periods with high resolution. In addition to the basic operating modes, T2 and T4 may be configured as reload or capture register for timer T3. A timer used as capture or reload register is stopped. The contents of timer T3 is captured into T2 or T4 in response to a signal at the associated input pin (TxIN). Timer T3 is reloaded with the contents of T2 or T4, triggered either by an external signal or a selectable state transition of its toggle latch T3OTL. When both T2 and T4 are configured to alternately reload T3 on opposite state transitions of T3OTL with the low and high times of a PWM signal, this signal can be continuously generated without software intervention. Note: Signals T2IN, T2EUD, T4EUD, and T6EUD are not connected to pins.

It includes two timers (T5, T6) and a capture/reload register (CAPREL). Both timers can be clocked with an input clock which is derived from the CPU clock via a programmable prescaler or with external signals. The counting direction (up/down) for each timer can be programmed by software or altered dynamically with an external signal on a port pin (TxEUD). Concatenation of the timers is supported with the output toggle latch (T6OTL) of timer T6, which changes its state on each timer overflow/underflow. The state of this latch may be used to clock timer T5, and/or it may be output on pin T6OUT. The overflows/underflows of timer T6 can also be used to clock the CAPCOM2 timers and to initiate a reload from the CAPREL register. The CAPREL register can capture the contents of timer T5 based on an external signal transition on the corresponding port pin (CAPIN); timer T5 may optionally be cleared after the capture procedure. This allows the XC223xN to measure absolute time differences or to perform pulse multiplication without software overhead. The capture trigger (timer T5 to CAPREL) can also be generated upon transitions of GPT1 timer T3 inputs T3IN and/or T3EUD. This is especially advantageous when T3 operates in Incremental Interface Mode.

The RTC basically consists of a chain of divider blocks: * * * Selectable 32:1 and 8:1 dividers (on - off) The reloadable 16-bit timer T14 The 32-bit RTC timer block (accessible via registers RTCH and RTCL) consisting of: - a reloadable 10-bit timer - a reloadable 6-bit timer - a reloadable 6-bit timer - a reloadable 10-bit timer All timers count up. Each timer can generate an interrupt request. All requests are combined to a common node request. fRTC :32 M UX RUN M UX Interrupt Sub Node :8 PRE REFCLK CNT INT0 CNT INT1 CNT INT2 RTCINT CNT INT3 REL-Register f CNT T14REL 10 Bits 6 Bits 6 Bits 10 Bits T14 10 Bits 6 Bits 6 Bits 10 Bits T14-Register CNT-Register M CB05568B Figure 10 RTC Block Diagram Note: The registers associated with the RTC are only affected by a power reset.

Conversions use the successive approximation method. The sample time (to charge the capacitors) and the conversion time are programmable so that they can be adjusted to the external circuit. The A/D converters can also operate in 8-bit conversion mode, further reducing the conversion time. Several independent conversion result registers, selectable interrupt requests, and highly flexible conversion sequences provide a high degree of programmability to meet the application requirements. Both modules can be synchronized to allow parallel sampling of two input channels. For applications that require more analog input channels, external analog multiplexers can be controlled automatically. For applications that require fewer analog input channels, the remaining channel inputs can be used as digital input port pins. The A/D converters of the XC223xN support two types of request sources which can be triggered by several internal and external events. * * Parallel requests are activated at the same time and then executed in a predefined sequence. Queued requests are executed in a user-defined sequence. In addition, the conversion of a specific channel can be inserted into a running sequence without disturbing that sequence. All requests are arbitrated according to the priority level assigned to them. Data reduction features reduce the number of required CPU access operations allowing the precise evaluation of analog inputs (high conversion rate) even at a low CPU speed. Result data can be reduced by limit checking or accumulation of results. The Peripheral Event Controller (PEC) can be used to control the A/D converters or to automatically store conversion results to a table in memory for later evaluation, without requiring the overhead of entering and exiting interrupt routines for each data transfer. Each A/D converter contains eight result registers which can be concatenated to build a result FIFO. Wait-for-read mode can be enabled for each result register to prevent the loss of conversion data. In order to decouple analog inputs from digital noise and to avoid input trigger noise, those pins used for analog input can be disconnected from the digital input stages. This can be selected for each pin separately with the Port x Digital Input Disable registers. The Auto-Power-Down feature of the A/D converters minimizes the power consumption when no conversion is in progress. Broken wire detection for each channel and a multiplexer test mode provide information to verify the proper operation of the analog signal sources (e.g. a sensor system). Data Sheet 49 V1.2, 2009-12 XC2232N, XC2234N, XC2236N, XC2238N XC2000 Family / Value Line Functional Description 3.12 Universal Serial Interface Channel Modules (USIC) The XC223xN features the USIC modules USIC0, USIC1, USIC2. Each module provides two serial communication channels. The Universal Serial Interface Channel (USIC) module is based on a generic data shift and data storage structure which is identical for all supported serial communication protocols. Each channel supports complete full-duplex operation with a basic data buffer structure (one transmit buffer and two receive buffer stages). In addition, the data handling software can use FIFOs. The protocol part (generation of shift clock/data/control signals) is independent of the general part and is handled by protocol-specific preprocessors (PPPs). The USIC's input/output lines are connected to pins by a pin routing unit. The inputs and outputs of each USIC channel can be assigned to different interface pins, providing great flexibility to the application software. All assignments can be made during runtime.

Please note that there may be additional delays, such as internal or external propagation delays and driver delays (e.g. for collision detection in UART mode, for IIC, etc.). Data Sheet 51 V1.2, 2009-12 XC2232N, XC2234N, XC2236N, XC2238N XC2000 Family / Value Line Functional Description 3.13 MultiCAN Module The MultiCAN module contains independently operating CAN nodes with Full-CAN functionality which are able to exchange Data and Remote Frames using a gateway function. Transmission and reception of CAN frames is handled in accordance with CAN specification V2.0 B (active). Each CAN node can receive and transmit standard frames with 11-bit identifiers as well as extended frames with 29-bit identifiers. All CAN nodes share a common set of message objects. Each message object can be individually allocated to one of the CAN nodes. Besides serving as a storage container for incoming and outgoing frames, message objects can be combined to build gateways between the CAN nodes or to set up a FIFO buffer. Note: The number of CAN nodes and message objects depends on the selected device type. The message objects are organized in double-chained linked lists, where each CAN node has its own list of message objects. A CAN node stores frames only into message objects that are allocated to its own message object list and it transmits only messages belonging to this message object list. A powerful, command-driven list controller performs all message object list operations. MultiCAN Module Kernel Clock Control CAN Node 0 Interrupt Control Port Control ...

Both timers can generate interrupt requests. The clock source can be selected and the timers can also run during power reduction modes. Therefore, the System Timer enables the software to maintain the current time for scheduling functions or for the implementation of a clock. 3.15 Watchdog Timer The Watchdog Timer is one of the fail-safe mechanisms which have been implemented to prevent the controller from malfunctioning for longer periods of time. The Watchdog Timer is always enabled after an application reset of the chip. It can be disabled and enabled at any time by executing the instructions DISWDT and ENWDT respectively. The software has to service the Watchdog Timer before it overflows. If this is not the case because of a hardware or software failure, the Watchdog Timer overflows, generating a prewarning interrupt and then a reset request. The Watchdog Timer is a 16-bit timer clocked with the system clock divided by 16,384 or 256. The Watchdog Timer register is set to a prespecified reload value (stored in WDTREL) in order to allow further variation of the monitored time interval. Each time it is serviced by the application software, the Watchdog Timer is reloaded and the prescaler is cleared. Time intervals between 3.2 s and 13.4 s can be monitored (@ 80 MHz). The default Watchdog Timer interval after power-up is 6.5 ms (@ 10 MHz). Data Sheet 53 V1.2, 2009-12 XC2232N, XC2234N, XC2236N, XC2238N XC2000 Family / Value Line Functional Description 3.16 Clock Generation The Clock Generation Unit can generate the system clock signal fSYS for the XC223xN from a number of external or internal clock sources: * * * * External clock signals with pad voltage or core voltage levels External crystal or resonator using the on-chip oscillator On-chip clock source for operation without crystal/resonator Wake-up clock (ultra-low-power) to further reduce power consumption The programmable on-chip PLL with multiple prescalers generates a clock signal for maximum system performance from standard crystals, a clock input signal, or from the on-chip clock source. See also Section 4.7.2. The Oscillator Watchdog (OWD) generates an interrupt if the crystal oscillator frequency falls below a certain limit or stops completely. In this case, the system can be supplied with an emergency clock to enable operation even after an external clock failure. All available clock signals can be output on one of two selectable pins. Data Sheet 54 V1.2, 2009-12 XC2232N, XC2234N, XC2236N, XC2238N XC2000 Family / Value Line Functional Description 3.17 Parallel Ports The XC223xN provides up to 40 I/O lines which are organized into 4 input/output ports and 2 input ports. All port lines are bit-addressable, and all input/output lines can be individually (bit-wise) configured via port control registers. This configuration selects the direction (input/output), push/pull or open-drain operation, activation of pull devices, and edge characteristics (shape) and driver characteristics (output current) of the port drivers. The I/O ports are true bidirectional ports which are switched to high impedance state when configured as inputs. During the internal reset, all port pins are configured as inputs without pull devices active. All port lines have alternate input or output functions associated with them. These alternate functions can be programmed to be assigned to various port pins to support the best utilization for a given application. For this reason, certain functions appear several times in Table 10. All port lines that are not used for alternate functions may be used as general purpose I/O lines.

Three mechanisms can be used (and partly in parallel): * * * Supply Voltage Management permits the temporary reduction of the supply voltage of major parts of the logic or even its complete disconnection. This drastically reduces the power consumed because it eliminates leakage current, particularly at high temperature. Several power reduction modes provide the best balance of power reduction and wake-up time. Clock Generation Management controls the frequency of internal and external clock signals. Clock signals for currently inactive parts of logic are disabled automatically. The user can drastically reduce the consumed power by reducing the XC223xN system clock frequency. External circuits can be controlled using the programmable frequency output EXTCLK. Peripheral Management permits temporary disabling of peripheral modules. Each peripheral can be disabled and enabled separately. The CPU can be switched off while the peripherals can continue to operate. Wake-up from power reduction modes can be triggered either externally with signals generated by the external system, or internally by the on-chip wake-up timer. This supports intermittent operation of the XC223xN by generating cyclic wake-up signals. Full performance is available to quickly react to action requests while the intermittent sleep phases greatly reduce the average system power consumption. Note: When selecting the supply voltage and the clock source and generation method, the required parameters must be carefully written to the respective bit fields, to avoid unintended intermediate states. Recommended sequences are provided which ensure the intended operation of power supply system and clock system. Please refer to the Programmer's Guide.

In this case the current must be limited to the listed values by design measures. Note: Stresses above the values listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for an extended time may affect device reliability. During absolute maximum rating overload conditions (VIN > VDDP or VIN < VSS) the voltage on VDDP pins with respect to ground (VSS) must not exceed the values defined by the absolute maximum ratings.

Separate buffer capacitors with the recomended values shall be connected as close as possible to each VDDI pin to keep the resistance of the board tracks below 2 Ohm. Connect all VDDI1 pins together. The minimum capacitance value is required for proper operation under all conditions (e.g. temperature). Higher values slightly increase the startup time. 2) Use one Capacitor for each pin. 3) This is the reference load. For bigger capacitive loads, use the derating factors listed in the PAD properties section. 4) The timing is valid for pin drivers operating in default current mode (selected after reset). Reducing the output current may lead to increased delays or reduced driving capability (CL). 5) The operating frequency range may be reduced for specific device types. This is indicated in the device designation (...FxxL). 80 MHz devices are marked ...F80L. 6) Overload conditions occur if the standard operating conditions are exceeded, i.e. the voltage on any pin exceeds the specified range: VOV > VIHmax (IOV > 0) or VOV < VILmin ((IOV < 0). The absolute sum of input overload currents on all pins may not exceed 50 mA. The supply voltages must remain within the specified limits. Proper operation under overload conditions depends on the application. Overload conditions must not occur on pin XTAL1 (powered by VDDI). 7) An overload current (IOV) through a pin injects a certain error current (IINJ) into the adjacent pins. This error current adds to the respective pins 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). The additional error current may distort the input voltage on analog inputs.

To aid in correctly interpreting the parameters when evaluating them for a design, they are marked accordingly in the column "Symbol": CC (Controller Characteristics): The logic of the XC223xN provides signals with the specified characteristics. SR (System Requirement): The external system must provide signals with the specified characteristics to the XC223xN. Data Sheet 63 V1.2, 2009-12 XC2232N, XC2234N, XC2236N, XC2238N XC2000 Family / Value Line Electrical Parameters 4.3 DC Parameters These parameters are static or average values that may be exceeded during switching transitions (e.g. output current). The XC223xN can operate within a wide supply voltage range from 3.0 V to 5.5 V. However, during operation this supply voltage must remain within 10 percent of the selected nominal supply voltage. It cannot vary across the full operating voltage range. Because of the supply voltage restriction and because electrical behavior depends on the supply voltage, the parameters are specified separately for the upper and the lower voltage range. During operation, the supply voltages may only change with a maximum speed of dV/dt < 1 V/ms. Leakage current is strongly dependent on the operating temperature and the voltage level at the respective pin. The maximum values in the following tables apply under worst case conditions, i.e. maximum temperature and an input level equal to the supply voltage. The value for the leakage current in an application can be determined by using the respective leakage derating formula (see tables) with values from that application. The pads of the XC223xN are designed to operate in various driver modes. The DC parameter specifications refer to the pad current limits specified in Section 4.7.4. Data Sheet 64 V1.2, 2009-12 XC2232N, XC2234N, XC2236N, XC2238N XC2000 Family / Value Line Electrical Parameters Pullup/Pulldown Device Behavior Most pins of the XC223xN feature pullup or pulldown devices. For some special pins these are fixed; for the port pins they can be selected by the application. The specified current values indicate how to load the respective pin depending on the intended signal level. Figure 13 shows the current paths. The shaded resistors shown in the figure may be required to compensate system pull currents that do not match the given limit values.

Hysteresis is implemented to avoid metastable states and switching due to internal ground bounce. It cannot suppress switching due to external system noise under all conditions. 3) If the input voltage exceeds the respective supply voltage due to ground bouncing (VIN < VSS) or supply ripple (VIN > VDDP), a certain amount of current may flow through the protection diodes. This current adds to the leakage current. An additional 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. 4) The given values are worst-case values. In production test, this leakage current is only tested at 125 C; other values are ensured by correlation. For derating, please refer to the following descriptions: Leakage derating depending on temperature (TJ = junction temperature [C]): IOZ = 0.05 x e(1.5 + 0.028 x TJ>) [A]. For example, at a temperature of 95 C the resulting leakage current is 3.2 A. Leakage derating depending on voltage level (DV = VDDP - VPIN [V]): IOZ = IOZtempmax - (1.6 x DV) (A]. This voltage derating formula is an approximation which applies for maximum temperature. 5) Drive the indicated minimum current through this pin to change the default pin level driven by the enabled pull device: VPIN <= VIL for a pullup; VPIN >= VIH for a pulldown. 6) These values apply to the fixed pull-devices in dedicated pins and to the user-selectable pull-devices in general purpose IO pins. 7) Limit the current through this pin to the indicated value so that the enabled pull device can keep the default pin level: VPIN >= VIH for a pullup; VPIN <= VIL for a pulldown. 8) The maximum deliverable output current of a port driver depends on the selected output driver mode. This specification is not valid for outputs which are switched to open drain mode. In this case the respective output will float and the voltage is determined by the external circuit. 9) As a rule, with decreasing output current the output levels approach the respective supply level (VOL->VSS, VOH->VDDP). However, only the levels for nominal output currents are verified.

This current adds to the leakage current. 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. 4) The given values are worst-case values. In production test, this leakage current is only tested at 125 C; other values are ensured by correlation. For derating, please refer to the following descriptions: Leakage derating depending on temperature (TJ = junction temperature [C]): IOZ = 0.05 x e(1.5 + 0.028 x TJ>) [A]. For example, at a temperature of 95 C the resulting leakage current is 3.2 A. Leakage derating depending on voltage level (DV = VDDP - VPIN [V]): IOZ = IOZtempmax - (1.6 x DV) (A]. This voltage derating formula is an approximation which applies for maximum temperature. 5) Drive the indicated minimum current through this pin to change the default pin level driven by the enabled pull device: VPIN <= VIL for a pullup; VPIN >= VIH for a pulldown. 6) These values apply to the fixed pull-devices in dedicated pins and to the user-selectable pull-devices in general purpose IO pins. 7) Limit the current through this pin to the indicated value so that the enabled pull device can keep the default pin level: VPIN >= VIH for a pullup; VPIN <= VIL for a pulldown. 8) The maximum deliverable output current of a port driver depends on the selected output driver mode. This specification is not valid for outputs which are switched to open drain mode. In this case the respective output will float and the voltage is determined by the external circuit. 9) As a rule, with decreasing output current the output levels approach the respective supply level (VOL->VSS, VOH->VDDP). However, only the levels for nominal output currents are verified.

The power consumption specified here consists of two components: * * The switching current IS depends on the device activity The leakage current ILK depends on the device temperature To determine the actual power consumption, always both components, switching current IS and leakage current ILK must be added: IDDP = IS + ILK. Note: The power consumption values are not subject to production test. They are verified by design/characterization. To determine the total power consumption for dimensioning the external power supply, also the pad driver currents must be considered. The given power consumption parameters and their values refer to specific operating conditions: * * * Active mode: Regular operation, i.e. peripherals are active, code execution out of Flash. Stopover mode: Crystal oscillator and PLL stopped, Flash switched off, clock in domain DMP_1 stopped. Standby mode: Voltage domain DMP_1 switched off completely, power supply control switched off. DMP_M domain is supplied by ultra low power electronic voltage regulator (ULPEVR). The alternate regulator EVR_M is switched off. Note: The maximum values cover the complete specified operating range of all manufactured devices. The typical values refer to average devices under typical conditions, such as nominal supply voltage, room temperature, application-oriented activity. After a power reset, the decoupling capacitors for VDDI are charged with the maximum possible current. For additional information, please refer to Section 5.2, Thermal Considerations.

Leaving SWD and PVC_M active adds another 90 A. Active Mode Power Supply Current The actual power supply current in active mode not only depends on the system frequency but also on the configuration of the XC223xN's subsystem. Besides the power consumed by the device logic the power supply pins also provide the current that flows through the pin output drivers. A small current is consumed because the drivers' input stages are switched. The IO power domains can be supplied separately. Power domain A (VDDPA) supplies the A/D converters and Port 6. Power domain B (VDDPB) supplies the on-chip EVVRs and all other ports.

The temperature difference between the junction temperature TJ and the ambient temperature TA must be taken into account.

For all other sectors the limit is 1,000 cycles. Access to the XC223xN Flash modules is controlled by the IMB. Built-in prefetch mechanisms optimize the performance for sequential access. Flash access waitstates only affect non-sequential access. Due to prefetch mechanisms, the performance for sequential access (depending on the software structure) is only partially influenced by waitstates.

Because the system clock signal fSYS can be generated from a number of internal and external sources using different mechanisms, the duration of the system clock periods (TCSs) and their variation (as well as the derived external timing) depend on the mechanism used to generate fSYS. This must be considered when calculating the timing for the XC223xN. Phase Locked Loop Operation (1:N) fI N f SYS TCS Direct Clock Drive (1:1) fI N f SYS TCS Prescaler Operation (N:1) fI N f SYS TCS M C_XC2X_CLOCKGEN Figure 19 Generation Mechanisms for the System Clock Note: The example of PLL operation shown in Figure 19 uses a PLL factor of 1:4; the example of prescaler operation uses a divider factor of 2:1. The specification of the external timing (AC Characteristics) depends on the period of the system clock (TCS). Data Sheet 85 V1.2, 2009-12 XC2232N, XC2234N, XC2236N, XC2238N XC2000 Family / Value Line Electrical Parameters Direct Drive When direct drive operation is selected (SYSCON0.CLKSEL = 11B), the system clock is derived directly from the input clock signal CLKIN1: fSYS = fIN. The frequency of fSYS is the same as the frequency of fIN. In this case the high and low times of fSYS are determined by the duty cycle of the input clock fIN. Selecting Bypass Operation from the XTAL11) input and using a divider factor of 1 results in a similar configuration. Prescaler Operation When prescaler operation is selected (SYSCON0.CLKSEL = 10B, PLLCON0.VCOBY = 1B), the system clock is derived either from the crystal oscillator (input clock signal XTAL1) or from the internal clock source through the output prescaler K1 (= K1DIV+1): fSYS = fOSC / K1. If a divider factor of 1 is selected, the frequency of fSYS equals the frequency of fOSC. In this case the high and low times of fSYS are determined by the duty cycle of the input clock fOSC (external or internal). The lowest system clock frequency results from selecting the maximum value for the divider factor K1: fSYS = fOSC / 1024. 4.7.2.1 Phase Locked Loop (PLL) When PLL operation is selected (SYSCON0.CLKSEL = 10B, PLLCON0.VCOBY = 0B), the on-chip phase locked loop is enabled and provides the system clock. The PLL multiplies the input frequency by the factor F (fSYS = fIN x F). F is calculated from the input divider P (= PDIV+1), the multiplication factor N (= NDIV+1), and the output divider K2 (= K2DIV+1): (F = N / (P x K2)). The input clock can be derived either from an external source at XTAL1 or from the onchip clock source. The PLL circuit synchronizes the system clock to the input clock. This synchronization is performed smoothly so that the system clock frequency does not change abruptly. Adjustment to the input clock continuously changes the frequency of fSYS so that it is locked to fIN. The slight variation causes a jitter of fSYS which in turn affects the duration of individual TCSs. 1) Voltages on XTAL1 must comply to the core supply voltage VDDI1. Data Sheet 86 V1.2, 2009-12 XC2232N, XC2234N, XC2236N, XC2238N XC2000 Family / Value Line Electrical Parameters The timing in the AC Characteristics refers to TCSs. Timing must be calculated using the minimum TCS possible under the given circumstances. The actual minimum value for TCS depends on the jitter of the PLL. Because the PLL is constantly adjusting its output frequency to correspond to the input frequency (from crystal or oscillator), the accumulated jitter is limited. This means that the relative deviation for periods of more than one TCS is lower than for a single TCS (see formulas and Figure 20). This is especially important for bus cycles using waitstates and for the operation of timers, serial interfaces, etc. For all slower operations and longer periods (e.g. pulse train generation or measurement, lower baudrates, etc.) the deviation caused by the PLL jitter is negligible. The value of the accumulated PLL jitter depends on the number of consecutive VCO output cycles within the respective timeframe. The VCO output clock is divided by the output prescaler K2 to generate the system clock signal fSYS. The number of VCO cycles is K2 x T, where T is the number of consecutive fSYS cycles (TCS). The maximum accumulated jitter (long-term jitter) DTmax is defined by: DTmax [ns] = (220 / (K2 x fSYS) + 4.3) This maximum value is applicable, if either the number of clock cycles T > (fSYS / 1.2) or the prescaler value K2 > 17. In all other cases for a timeframe of T x TCS the accumulated jitter DT is determined by: DT [ns] = DTmax x [(1 - 0.058 x K2) x (T - 1) / (0.83 x fSYS - 1) + 0.058 x K2] fSYS in [MHz] in all formulas. Example, for a period of 3 TCSs @ 33 MHz and K2 = 4: Dmax = (220 / (4 x 33) + 4.3) = 5.97 ns (Not applicable directly in this case!) D3 = 5.97 x [(1 - 0.058 x 4) x (3 - 1) / (0.83 x 33 - 1) + 0.058 x 4] = 5.97 x [0.768 x 2 / 26.39 + 0.232] = 1.7 ns Example, for a period of 3 TCSs @ 33 MHz and K2 = 2: Dmax = (220 / (2 x 33) + 4.3) = 7.63 ns (Not applicable directly in this case!) D3 = 7.63 x [(1 - 0.058 x 2) x (3 - 1) / (0.83 x 33 - 1) + 0.058 x 2] = 7.63 x [0.884 x 2 / 26.39 + 0.116] = 1.4 ns Data Sheet 87 V1.2, 2009-12 XC2232N, XC2234N, XC2236N, XC2238N XC2000 Family / Value Line Electrical Parameters Acc. jitter DT ns 9 fSYS = 33 MHz fSYS = 66 MHz fVCO = 66 MHz 8 7 f VCO = 132 MHz 6 5 4 3 2 1 Cycles T 0 1 20 40 60 80 100 MC_XC2X_JITTER Figure 20 Approximated Accumulated PLL Jitter Note: The specified PLL jitter values are valid if the capacitive load per pin does not exceed CL = 20 pF. The maximum peak-to-peak noise on the pad supply voltage (measured between VDDPB pin 64 and VSS pin 1) is limited to a peak-to-peak voltage of VPP = 50 mV. This can be achieved by appropriate blocking of the supply voltage as close as possible to the supply pins and using PCB supply and ground planes. PLL frequency band selection Different frequency bands can be selected for the VCO so that the operation of the PLL can be adjusted to a wide range of input and output frequencies: Data Sheet 88 V1.2, 2009-12 XC2232N, XC2234N, XC2236N, XC2238N XC2000 Family / Value Line Electrical Parameters Table 26 System PLL Parameters Parameter Symbol Values Min.

In this mode, a basic functionality can be maintained without requiring an external clock source and while minimizing the power consumption. 4.7.2.3 Selecting and Changing the Operating Frequency When selecting a clock source and the clock generation method, the required parameters must be carefully written to the respective bit fields, to avoid unintended intermediate states. Many applications change the frequency of the system clock (fSYS) during operation in order to optimize system performance and power consumption. Changing the operating frequency also changes the switching currents, which influences the power supply. To ensure proper operation of the on-chip EVRs while they generate the core voltage, the operating frequency shall only be changed in certain steps. This prevents overshoots and undershoots of the supply voltage.

The clock can be generated in two ways: * * By connecting a crystal or ceramic resonator to pins XTAL1/XTAL2. By supplying an external clock signal. This clock signal can be supplied either to pin XTAL1 (core voltage domain) or to pin CLKIN1 (IO voltage domain). If connected to CLKIN1, the input signal must reach the defined input levels VIL and VIH. If connected to XTAL1, a minimum amplitude VAX1 (peak-to-peak voltage) is sufficient for the operation of the on-chip oscillator. Note: The given clock timing parameters (t1 ... t4) are only valid for an external clock input signal. Note: Operating Conditions apply.

Strong driver mode allows controlling external components requiring higher currents such as power bridges or LEDs. Reducing the driving power of an output pad reduces electromagnetic emissions (EME). In strong driver mode, selecting a slower edge reduces EME. The dynamic behavior, i.e. the rise time and fall time, depends on the applied external capacitance that must be charged and discharged. Timing values are given for a capacitance of 20 pF, unless otherwise noted. In general, the performance of a pad driver depends on the available supply voltage VDDP. Therefore the following tables list the pad parameters for the upper voltage range and the lower voltage range, respectively. Note: These parameters are not subject to production test but verified by design and/or characterization. Note: Operating Conditions apply.

Note: To improve the EMC behavior, it is recommended to connect the exposed pad to the board ground, independent of the thermal requirements. Board layout examples are given in an application note. Package Compatibility Considerations The XC223xN is a member of the XC2000 Family of microcontrollers. It is also compatible to a certain extent with members of similar families or subfamilies. Each package is optimized for the device it houses. Therefore, there may be slight differences between packages of the same pin-count but for different device types. In particular, the size of the Exposed Pad (if present) may vary. If different device types are considered or planned for an application, it must be ensured that the board layout fits all packages under consideration.

The maximum heat that can be dissipated depends on the package and its integration into the target board. The "Thermal resistance RJA" quantifies these parameters. The power dissipation must be limited so that the average junction temperature does not exceed 150 C. The difference between junction temperature and ambient temperature is determined by T = (PINT + PIOSTAT + PIODYN) x RJA The internal power consumption is defined as PINT = VDDP x IDDP (switching current and leakage current). The static external power consumption caused by the output drivers is defined as PIOSTAT = ((VDDP-VOH) x IOH) + (VOL x IOL) The dynamic external power consumption caused by the output drivers (PIODYN) depends on the capacitive load connected to the respective pins and their switching frequencies. If the total power dissipation for a given system configuration exceeds the defined limit, countermeasures must be taken to ensure proper system operation: * * * * Reduce VDDP, if possible in the system Reduce the system frequency Reduce the number of output pins Reduce the load on active output drivers Data Sheet 108 V1.2, 2009-12 w w w . i n f i n e o n . c o m Published by Infineon Technologies AG
