Functional Description
The architecture of the XC228x 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 XC228x. The following block diagram gives an overview of the different on-chip components and of the advanced, high bandwidth internal bus structure of the XC228x.

XC2287 / XC2286 / XC2285 XC2000 Family Derivatives
Preliminary Functional Description
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 byte wise or word wise. Portions of the on-chip DPRAM and the register spaces (ESFR/SFR) have additionally been made 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 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 USIC or MultiCAN). The system bus allows concurrent two-way communication for maximum transfer performance. Up to 64 Kbytes of on-chip Program SRAM (PSRAM) are provided to store user code or data. The PSRAM is accessed via the PMU and is therefore optimized for code fetches. A section of the PSRAM with programmable size can be write-protected. Note: The actual size of the PSRAM depends on the chosen derivative (see Table 1). 16 Kbytes of on-chip Data SRAM (DSRAM) are provided as a storage for general user data. The DSRAM is accessed via a separate interface 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, 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) so-called General Purpose Registers (GPRs). The upper 256 bytes of the DPRAM are directly bit addressable. When used by a GPR, any location in the DPRAM is bit addressable. 1 Kbyte of on-chip Stand-By SRAM (SBRAM) is provided as a storage for systemrelevant 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 via domain M.

XC2287 / XC2286 / XC2285 XC2000 Family Derivatives
Preliminary Functional Description
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 for controlling and monitoring functions of the different on-chip units. Unused SFR addresses are reserved for future members of the XC2000 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. The External Bus Interface also provides access to external peripherals. Up to 768 Kbytes of on-chip Flash memory store code, constant data, and control data. The on-chip Flash memory consists of up to 3 modules with a maximum capacity of 256 Kbytes each. Each module is organized in 4-Kbyte sectors. One 4-Kbyte sector of Flash module 0 is used internally to store operation control parameters and protection information. Note: The actual size of the Flash memory depends on the chosen derivative (see Table 1). Each sector can be separately write protected1), erased and programmed (in blocks of 128 Bytes). The complete Flash area can be read-protected. A user-defined password sequence temporarily unlocks protected areas. The Flash modules combine 128-bit read accesses with protected and efficient writing algorithms for programming and erasing. Dynamic error correction provides extremely high read data security for all read accesses. Accesses to different Flash modules can be executed in parallel. For timing characteristics, please refer to Section 4.4.2, for further Flash parameters, please refer to Section 5.3.
1) To save control bits, sectors are clustered for protection purposes, they remain separate for programming/erasing.

Preliminary Functional Description
3.2
External Bus Controller
All of the external memory accesses are performed by a particular on-chip External Bus Controller (EBC). The EBC also controls accesses to resources connected to the on-chip LXBus (MultiCAN and the USIC modules). The LXBus is an internal representation of the external bus and allows accessing integrated peripherals and modules in the same way as external components. The EBC can be programmed either to Single Chip Mode when no external memory is required, or to an external bus mode with the following possible selections1): * * * Address Bus Width with a range of 0 ... 24-bit Data Bus Width 8-bit or 16-bit Bus Operation Multiplexed or Demultiplexed
The bus interface uses Port 10 and Port 2 for addresses and data. In the demultiplexed bus modes, the lower addresses are separately output on Port 0 and Port 1. The number of active segment address lines is selectable, restricting the external address space to 8 Mbytes ... 64 Kbytes. This is required when interface lines shall be assigned to Port 2. Up to 5 external CS signals (4 windows plus default) can be generated and output on Port 4 in order to save external glue logic. External modules can directly be connected to the common address/data bus and their individual select lines. A HOLD/HLDA protocol is available for bus arbitration and allows the sharing of external resources with other bus masters. The bus arbitration is enabled by software. After enabling, pins P3.0 ... P3.2 (BREQ, HLDA, HOLD) are automatically controlled by the EBC. In Master Mode (default after reset) the HLDA pin is an output. In Slave Mode pin HLDA is switched to input. This allows the direct connection of the slave controller to another master controller without glue logic. Important timing characteristics of the external bus interface have been made programmable (via registers TCONCSx/FCONCSx) to allow the user the adaption of a wide range of different types of memories and external peripherals. Access to very slow memories or modules with varying access times is supported via a particular `Ready' function. The active level of the control input signal is selectable. In addition, up to 4 independent address windows may be defined (via registers ADDRSELx) which control accesses to resources with different bus characteristics. These address windows are arranged hierarchically where window 4 overrides window 3, and window 2 overrides window 1. All accesses to locations not covered by these 4 address windows are controlled by TCONCS0/FCONCS0. The currently active window can generate a chip select signal. The external bus timing is related to the rising edge of the reference clock output CLKOUT. The external bus protocol is compatible with that of the standard C166 Family.
1) Bus modes are switched dynamically if several address windows with different mode settings are used.

XC2287 / XC2286 / XC2285 XC2000 Family Derivatives
Preliminary Functional Description
Based on these hardware provisions, most of the XC228x's instructions can be executed in just one machine cycle which requires 15 ns at 66 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. Also multiplication and most MAC instructions execute in one single cycle. All multiple-cycle instructions have been optimized so that they can be executed very fast as well: 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, allows eliminating the execution time of branch instructions if the prediction was correct. The CPU has a register context consisting of up to three register banks with 16 word wide GPRs each at its disposal. One of these register banks is physically allocated within the on-chip DPRAM area. A Context Pointer (CP) register determines the base address of the active register bank to be 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 as a storage for temporary data. The system stack can be allocated to any location within the address space (preferably 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 XC228x instruction set which 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.

Interrupt System
With an interrupt response time of typically 8 CPU clocks (in case of internal program execution), the XC228x is capable of reacting very fast to the occurrence of nondeterministic events. The architecture of the XC228x 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, 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 very well suited, for example, for supporting the transmission or reception of blocks of data. The XC228x 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 bit field exists for each of the possible interrupt nodes. Via its related register, each node 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 nodes 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. Table 4 shows all of the possible XC228x interrupt sources and the corresponding hardware-related interrupt flags, vectors, vector locations and trap (interrupt) numbers. Note: Interrupt nodes which are not assigned to peripherals (unassigned nodes), may be used to generate software controlled interrupt requests by setting the respective interrupt request bit (xIR).

Preliminary Functional Description
The XC228x 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 occurrence of a hardware trap is additionally signified by an individual bit in the trap flag register (TFR). Except when another higher prioritized trap service is in progress, a hardware trap will interrupt any actual program execution. In turn, hardware trap services can normally not be interrupted by standard or PEC interrupts. Table 5 shows all of the possible exceptions or error conditions that can arise during runtime: Table 5 Hardware Trap Summary Trap Flag - SR0 STKOF STKUF SOFTBRK SR1 UNDOPC ACER PRTFLT ILLOPA - - Trap Vector RESET SR0TRAP STOTRAP STUTRAP SBRKTRAP BTRAP BTRAP BTRAP BTRAP BTRAP - - Vector Trap Trap 1) Location Number Priority xx'0000H xx'0008H xx'0010H xx'0018H xx'0020H xx'0028H xx'0028H xx'0028H xx'0028H xx'0028H 00H 02H 04H 06H 08H 0AH 0AH 0AH 0AH 0AH III II II II II I I I I I - Current CPU Priority

On-Chip Debug Support (OCDS)
The On-Chip Debug Support system provides a broad range of debug and emulation features built into the XC228x. The user software running on the XC228x can thus be debugged within the target system environment. The OCDS is controlled by an external debugging device via the debug interface, consisting of the IEEE-1149-conforming JTAG port and a break interface. The debugger controls the OCDS via a set of dedicated registers accessible via the JTAG interface. Additionally, the OCDS system can be controlled by the CPU, e.g. by a monitor program. An injection interface allows the execution of OCDS-generated instructions by the CPU. Multiple breakpoints can be triggered by on-chip hardware, by software, or by an external trigger input. Single stepping is supported as well as the injection of arbitrary instructions and read/write access to the complete internal address space. A breakpoint trigger can be answered with a CPU-halt, a monitor call, a data transfer, or/and the activation of an external signal. Tracing data can be obtained via the JTAG interface or via the external bus interface for increased performance. The debug interface uses a set of 6 interface signals (4 JTAG lines, 2 optional break lines) to communicate with external circuitry.

Capture/Compare Unit (CAPCOM2)
The CAPCOM2 unit supports generation and control of timing sequences on up to 16 channels with a maximum resolution of 1 system clock cycle (8 cycles in staggered mode). The CAPCOM2 unit is typically used to handle high speed I/O tasks such as pulse and waveform generation, pulse width modulation (PWM), Digital to Analog (D/A) conversion, software timing, or time recording relative to external events. Two 16-bit timers (T7/T8) with reload registers provide two independent time bases for the capture/compare register array. The input clock for the timers is programmable to 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, an external count input for CAPCOM2 timer T7 allows 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 CAPCOM2 timer T7 or T8 and programmed for capture or compare function. All registers of the CAPCOM2 module 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. Table 6 Mode 0 Mode 1 Mode 2 Mode 3 Double Register Mode Single Event Mode Compare Modes (CAPCOM2) Function Interrupt-only compare mode; Several compare interrupts per timer period are possible Pin toggles on each compare match; Several compare events per timer period are possible Interrupt-only compare mode; Only one compare interrupt per timer period is generated Pin set `1' on match; pin reset `0' on compare timer overflow; Only one compare event per timer period is generated Two registers operate on one pin; Pin toggles on each compare match; Several compare events per timer period are possible Generates single edges or pulses; Can be used with any compare mode
Compare Modes
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

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.

General Purpose Timer (GPT12E) Unit
The GPT12E 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 GPT12E unit incorporates five 16-bit timers which are organized in two separate modules, GPT1 and GPT2. Each timer in each module may operate independently in a number of different modes, or may 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, which are Timer, Gated Timer, Counter, and Incremental Interface Mode. In Timer Mode, the input clock for a timer is derived from the system 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, each timer has one associated port pin (TxIN) which serves as gate or clock input. The maximum resolution of the timers in module GPT1 is 4 system clock cycles. The count direction (up/down) for each timer is programmable by software or may additionally be altered dynamically by an external signal on a port pin (TxEUD) to facilitate e.g. position tracking. In Incremental Interface Mode the GPT1 timers (T2, T3, T4) can be directly connected to the incremental position sensor signals A and B via their respective inputs TxIN and TxEUD. Direction and count signals are internally derived from these two input signals, so the contents of the respective timer Tx corresponds to the sensor position. The third position sensor signal TOP0 can be connected to an interrupt input. Timer T3 has an output toggle latch (T3OTL) which changes its state on each timer 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 their basic operating modes, timers T2 and T4 may be configured as reload or capture registers for timer T3. When used as capture or reload registers, timers T2 and T4 are stopped. The contents of timer T3 is captured into T2 or T4 in response to a signal at their associated input pins (TxIN). Timer T3 is reloaded with the contents of T2 or T4 triggered either by an external signal or by a selectable state transition of its toggle latch T3OTL. 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 constantly generated without software intervention.

Preliminary Functional Description
With its maximum resolution of 2 system clock cycles, the GPT2 module provides precise event control and time measurement. It includes two timers (T5, T6) and a capture/reload register (CAPREL). Both timers can be clocked with an input clock which is derived from the CPU clock via a programmable prescaler or with external signals. The count direction (up/down) for each timer is programmable by software or may additionally be altered dynamically by an external signal on a port pin (TxEUD). Concatenation of the timers is supported via 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 additionally be used to clock the CAPCOM2 timers, and to cause a reload from the CAPREL register. The CAPREL register may capture the contents of timer T5 based on an external signal transition on the corresponding port pin (CAPIN), and timer T5 may optionally be cleared after the capture procedure. This allows the XC228x to measure absolute time differences or to perform pulse multiplication without software overhead. The capture trigger (timer T5 to CAPREL) may also be generated upon transitions of GPT1 timer T3's inputs T3IN and/or T3EUD. This is especially advantageous when T3 operates in Incremental Interface Mode.

A/D Converters
For analog signal measurement, up to two 10-bit A/D converters (ADC0, ADC1) with 16 (or 8) multiplexed input channels including a sample and hold circuit have been integrated on-chip. They use the method of successive approximation. The sample time (for loading the capacitors) and the conversion time are programmable and can thus be adjusted to the external circuitry. The A/D converters can also operate in 8-bit conversion mode, where the conversion time is further reduced. Several independent conversion result registers, selectable interrupt requests, and highly flexible conversion sequences provide a high degree of programmability to fulfill the requirements of the respective application. 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 less analog input channels, the remaining channel inputs can be used as digital input port pins. The A/D converters of the XC228x 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 this sequence. All requests are arbitrated according to the priority level that has been assigned to them. Data reduction features, such as limit checking or result accumulation, reduce the number of required CPU accesses and so allow the precise evaluation of analog inputs (high conversion rate) even at low CPU speed. The Peripheral Event Controller (PEC) may be used to control the A/D converters or to automatically store conversion results into a table in memory for later evaluation, without requiring the overhead of entering and exiting interrupt routines for each data transfer. Therefore, each A/D converter contains 8 result registers which can be concatenated to build a result FIFO. Wait-for-read mode can be enabled for each result register to prevent loss of conversion data. In order to decouple analog inputs from digital noise and to avoid input trigger noise those pins used for analog input can be disconnected from the digital input stages under software control. This can be selected for each pin separately via registers P5_DIDIS and P15_DIDIS (Port x Digital Input Disable). The Auto-Power-Down feature of the A/D converters minimizes the power consumption when no conversion is in progress.

Universal Serial Interface Channel Modules (USIC)
The XC228x features three USIC modules (USIC0, USIC1, USIC2), each providing two serial communication channels. The Universal Serial Interface Channel (USIC) module is based on a generic data shift and data storage structure which is identical for all supported serial communication protocols. Each channel supports complete full-duplex operation with a basic data buffer structure (one transmit buffer and two receive buffer stages). In addition, the data handling software can use FIFOs. The protocol part (generation of shift clock/data/control signals) is independent from 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, so 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 done during runtime.

MultiCAN Module
The MultiCAN module contains up to five independently operating CAN nodes with FullCAN functionality which are able to exchange Data and Remote Frames via a gateway function. Transmission and reception of CAN frames is handled in accordance with CAN specification V2.0 B (active). Each CAN node can receive and transmit standard frames with 11-bit identifiers as well as extended frames with 29-bit identifiers. All CAN nodes share a common set of 128 message objects. Each message object can be individually allocated to one of the CAN nodes. Besides serving as a storage container for incoming and outgoing frames, message objects can be combined to build gateways between the CAN nodes or to setup a FIFO buffer. The message objects are organized in double-chained linked lists, where each CAN node has its own list of message objects. A CAN node stores frames only into message objects that are allocated to its own message object list, and it transmits only messages belonging to this message object list. A powerful, command-driven list controller performs all message object list operations.

Watchdog Timer
The Watchdog Timer 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 and enabled at any time by executing instructions DISWDT and ENWDT. Thus, the chip's 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 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. Thus, time intervals between 3.9 s and 16.3 s can be monitored (@ 66 MHz). The default Watchdog Timer interval after power-up is 6.5 ms (@ 10 MHz).

The programmable on-chip PLL with multiple prescalers generates a clock signal for maximum system performance from standard crystals or from the on-chip oscillator. See also Section 4.4.1. 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 also be output on one of two selectable pins.

Parallel Ports
The XC228x provides up to 118 I/O lines which are organized into 11 input/output ports and 2 input ports. All port lines are bit-addressable, and all input/output lines can be individually (bit-wise) configured via port control registers. This configuration selects the direction (input/output), push/pull or open-drain operation, activation of pull devices, and edge characteristics (shape) and driver characteristics (output current) of the port drivers. The I/O ports are true bidirectional ports which are switched to high impedance state when configured as inputs. During the internal reset, all port pins are configured as inputs without pull devices active. All port lines have programmable alternate input or output functions associated with them. These alternate functions can be assigned to various port pins to support the optimal utilization for a given application. For this reason, certain functions appear several times in Table 7. All port lines that are not used for these alternate functions may be used as general purpose I/O lines.

Power Management
The XC228x 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): * Supply Voltage Management allows the temporary reduction of the supply voltage of major parts of the logic, or even the complete disconnection. This drastically reduces the power consumed because of leakage current, in particular at high temperature. Several power reduction modes provide the optimal balance of power reduction and wake-up time. Clock Generation Management controls 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 XC228x's system clock frequency which drastically reduces the consumed power. External circuitry can be controlled via the programmable frequency output EXTCLK. Peripheral Management permits temporary disabling of peripheral modules. Each peripheral can separately be disabled/enabled. Also the CPU can be switched off while the peripherals can continue to operate.
*
*
Wake-up from power reduction modes can be triggered either externally by signals generated by the external system, or internally by the on-chip wake-up timer, which supports intermittent operation of the XC228x 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. Note: When selecting the supply voltage and the clock source and generation method, the required parameters must be carefully written to the respective bitfields, to avoid unintended intermediate states. Recommended sequences are provided which ensure the intended operation of power supply system and clock system.

Pin drivers in default mode7) For each core domain8) See Table 1
1) In case both core power domains are clocked, the difference between the power supply voltages must be less than 10mV. This condition imposes additional constraints when using external power supplies. In order to supply both core power domains, two independent external voltage regulators may not be used. The simplest possibility is to supply both power domains directly via a single external power supply. 2) Performance of pad drivers, A/D Converter, and Flash module depends on VDDP. 3) This limitation must be fulfilled under all operating conditions including power-ramp-up, power-ramp-down, and power-save modes, if VDDI is supplied externally. 4) 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). 5) Not subject to production test - verified by design/characterization. 6) 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| x KOV). The additional error current may distort the input voltage on analog inputs. 7) 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). 8) To ensure the stability of the voltage regulators each core voltage domain must be buffered with a ceramic capacitor. For domain M a 680 nF capacitor is recommended, for domain 1 three 220 nF capacitors are recommended. All buffer capacitors must be connected als close to the VDDI pins as possible to keep the resistance of the board tracks below 2 .

DC Parameters
These parameters are static or average values, which may be exceeded during switching transitions (e.g. output current). The XC228x can operate within a wide supply voltage range from 3.0 V to 5.5 V. However, during operation this supply voltage must not vary within the complete operating voltage range, but must remain within a certain band of 10% of the chosen nominal supply voltage. For this reason and because the electrical behaviour partly depends on the supply voltage, the parameters are specified twice for the upper and the lower voltage area. During operation, the supply voltages may only change with a maximum speed of dV/dt < 1 V/ms. The leakage currents strongly depend on the operating temperature and the actual voltage level at the respective pin. The maximum values given in the following tables apply under worst case conditions, i.e. maximum temperature and an input level equal to the supply voltage. The actual value for the leakage current can be determined by evaluating the respective leakage derating formula (see tables) using values from the actual application. The pads of the XC228x are designed to operate in various driver modes. The DC parameter specifications refer to the current limits given in Table 11.

Power Consumption
The amount of power that is consumed by the XC228x depends on several factors, such as supply voltage, operating frequency, amount of active circuitry, and operating temperature. Part of this depends on the device's activity (switching current), part of this is independent (leakage current). Therefore, the leakage current must be added to all other (frequency-dependent) parameters. For additional information, please refer to Section 5.2, Thermal Considerations.

1) The supply current caused by leakage mainly depends on the junction temperature (see Figure 12) and the supply voltage. The temperature difference between the junction temperature TJ and the ambient temperature TA must be taken into account. As this fraction of the supply current does not depend on the device's activity, it must be added to each other power consumption parameter. 2) 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. 3) The pad supply voltage pins (VDDP) provide the input current for the on-chip EVVRs and the current consumed by the pin output drivers. A small amount of current is consumed because the drivers' input stages are switched.

4.4.1
Definition of Internal Timing
The internal operation of the XC228x is controlled by the internal system clock fSYS. Because the system clock signal fSYS can be generated from several internal and external sources via different mechanisms, the duration of system clock periods (TCSs) and their variation (and also the derived external timing) depend on the used mechanism to generate fSYS. This influence must be regarded when calculating the timings for the XC228x.

Data Sheet 87 V0.91, 2007-02 Draft Version
XC2287 / XC2286 / XC2285 XC2000 Family Derivatives
Preliminary Electrical Parameters
The specification of the external timing (AC Characteristics) depends on the period of the system clock (TCS). Direct Drive When direct drive operation is configured (SYSCON0.CLKSEL = 11B), the system clock is derived directly from the input clock signal DIRIN:
fSYS = fIN.
The frequency of fSYS directly follows the frequency of fIN. In this case, the high and low time of fSYS is defined by the duty cycle of the input clock fIN. A similar configuration can be achieved by selecting the XTAL11) input. Prescaler Operation When prescaler operation is configured (SYSCON0.CLKSEL = 10B, PLLCON0.VCOBY = 1B), the system clock is derived either from the crystal oscillator (input clock signal XTAL1) or from the internal oscillator through the output-prescaler:
fSYS = fOSC / (K1DIV + 1).
If the divider factor is selected as 1, the frequency of fSYS directly follows the frequency of fOSC. In this case, the high and low time of fSYS is defined by the duty cycle of the input clock fOSC (external or internal). The lowest system clock frequency can be achieved in this mode by selecting the maximum value for divider factor K1:
fSYS = fOSC / 1024.
Phase Locked Loop (PLL) When PLL operation is configured (SYSCON0.CLKSEL = 10B, PLLCON0.VCOBY = 0B), the on-chip phase locked loop provides the system clock. The PLL multiplies the selected input frequency by the factor F (fSYS = fIN x F), which results from the input divider (P), the multiplication factor (N), and the output divider (K2): (F = N+1 / (P+1 x K2+1)). The input clock can be derived either from an external source via XTAL1 or from the onchip oscillator. The PLL circuit synchronizes the system clock to the input clock. This synchronization is done smoothly, i.e. the system clock frequency does not change abruptly. Due to this adaptation to the input clock the frequency of fSYS is constantly adjusted so it is locked to fIN. The slight variation causes a jitter of fSYS which also affects the duration of individual TCSs.
1) Voltages on XTAL1 must comply to the core supply voltage VDDI1.

V0.91, 2007-02 Draft Version
XC2287 / XC2286 / XC2285 XC2000 Family Derivatives
Preliminary Electrical Parameters
The timing listed in the AC Characteristics refers to TCSs. Therefore, the timing must be calculated using the minimum TCS possible under the respective circumstances. The actual minimum value for TCS 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 accumulated jitter is limited, which means that the relative deviation for periods of more than one TCS is lower than for one single TCS. This is especially important for bus cycles using waitstates and e.g. for the operation of timers, serial interfaces, etc. For all slower operations and longer periods (e.g. pulse train generation or measurement, lower baudrates, etc.) the deviation caused by the PLL jitter is, therefore, 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+1) to generate the system clock signal fSYS. Therefore, the number of VCO cycles can be represented as (K2+1) x T, where T is the number of consecutive fSYS cycles (TCS). 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: Table 17 00 01 1X VCO Bands for PLL Operation1) Base Frequency Range 10 ... 40 MHz 20 ... 80 MHz 40 ... 120 MHz 90 ... 160 MHz Reserved

1) Not subject to production test - verified by design/characterization.
Wakeup Oscillator When wakeup oscillator operation is configured (SYSCON0.CLKSEL = 00B), the system clock is derived from the low-frequency wakeup oscillator:
fSYS = fWU.
In this mode, a basic functionality can be maintained without requiring an external clock source and while minimizing the power consumption.

XC2287 / XC2286 / XC2285 XC2000 Family Derivatives
Preliminary Selecting and Changing the Operating Frequency When selecting a clock source and the clock generation method, the required parameters must be carefully written to the respective bitfields, to avoid unintended intermediate states. Many applications change the frequency of the system clock (fSYS) during the operation, to optimize performance and power consumption of the system. Changing the operating frequency also changes the consumed switching current, which influences the power supply. Therefore, while the core voltage is generated by the on-chip EVRs, the operating frequency may only be changed by factors of 5 maximum, or in steps of 20 MHz maximum, whatever condition is tighter. To avoid the indicated problems, recommended sequences are provided which ensure the intended operation of the clock system interacting with the power system. Electrical Parameters

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

Preliminary Variable Memory Cycles External bus cycles of the XC228x are executed in five subsequent cycle phases (AB, C, D, E, F). The duration of each cycle phase is programmable (via the TCONCSx registers) to adapt the external bus cycles to the respective external module (memory, peripheral, etc.). The duration of the access phase can optionally be controlled by the external module via the READY handshake input. This table provides a summary of the phases and the respective choices for their duration.

Note: The bandwidth of a parameter (minimum and maximum value) covers the whole operating range (temperature, voltage) as well as process variations. Within a given device, however, this bandwidth is smaller than the specified range. This is also due to interdependencies between certain parameters. Some of these interdependencies are described in additional notes (see standard timing). Timing values are listed in Table 22 and Table 23. The shaded parameters have been verified by characterization. They are not subject to production test.

1) Read data are latched with the same (internal) clock edge that triggers the address change and the rising edge of RD. Therefore address changes before the end of RD have no impact on (demultiplexed) read cycles. Read data can be removed after the rising edge of RD.

Preliminary Bus Cycle Control via READY Input The duration of an external bus cycle can be controlled by the external circuitry via the READY input signal. The polarity of this input signal can be selected. Synchronous READY permits the shortest possible bus cycle but requires the input signal to be synchronous to the reference signal CLKOUT. Asynchronous READY puts no timing constraints on the input signal but incurs one waitstate minimum due to the additional synchronization stage. The minimum duration of an asynchronous READY signal to be safely synchronized must be one CLKOUT period plus the input setup time. An active READY signal can be deactivated in response to the trailing (rising) edge of the corresponding command (RD or WR). If the next following bus cycle is READY-controlled, an active READY signal must be disabled before the first valid sample point for the next bus cycle. This sample point depends on the programmed phases of the next following cycle. Electrical Parameters

Note: If the READY input is sampled inactive at the indicated sampling point ("Not Rdy") a READY-controlled waitstate is inserted (tpRDY), sampling the READY input active at the indicated sampling point ("Ready") terminates the currently running bus cycle. Note the different sampling points for synchronous and asynchronous READY. This example uses one mandatory waitstate (see tpE) before the READY input is evaluated.

Please note that HOLD may also be deactivated without the XC228x requesting the bus. 2. The control outputs will be resistive high (pull-up) before being driven inactive (ALE will be low). 3.

Thermal Considerations
When operating the XC228x in a system, the total heat generated on the chip must be dissipated to the ambient environment to prevent overheating and resulting thermal damages. The maximum heat that can be dissipated depends on the package and its integration into the target board. The "Thermal resistance RJA" is a measure for these parameters. The power dissipation must be limited so 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 (see Table 14). 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 the switching frequencies. If the total power dissipation determined 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
