If a system uses the PORST reset input for other system resets, it has to be taken into account, that the emulation part of the TC1766ED Emulation Device is reset also. It thus will force always a complete re-initialization of the emulator and will prevent the user debugging across these types of resets. 9) Input only pads without input spike filter.

The Local Memory Bus interconnects the memory units and functional units, such as CPU and PMU. The main target of the LMB bus is to support devices with fast response times, optimized for speed. This allows the DMI and PMI fast access to local memory and reduces load on the FPI bus. The Tricore system itself is located on LMB bus. The Local Memory Bus is a synchronous, pipelined, split bus with variable block size transfer support. It supports 8-, 16-, 32- and 64-bit single transactions and variable length 64-bit block transfers. The SPB Bus is mainly governed by the PCP and is accessible to the CPU via the LMB Bus bridge. The System Peripheral Bus (SPB Bus) in TC1764 is an on-chip FPI Bus. The FPI Bus interconnects the functional units of the TC1764, such as the DMA and on-chip peripheral components. The FPI Bus is designed to be quick to be acquired by on-chip functional units, and quick to transfer data. The low setup overhead of the FPI Bus access protocol guarantees fast FPI Bus acquisition, which is required for time-critical applications.The FPI Bus is designed to sustain high transfer rates. For example, a peak transfer rate of up to 320 Mbyte/s can be achieved with a 80 MHz bus clock and 32-bit data bus. Multiple data transfers per bus arbitration cycle allow the FPI Bus to operate at close to its peak bandwidth. Both the LMB Bus and the SPB Bus runs at full CPU speed. The maximum CPU speed is 80 MHz. Additionally, two simplified bus interfaces are connected to and controlled by the DMA Controller: * * DMA Bus SMIF Interface Data Sheet 24 V1.0, 2008-04 TC1764 Preliminary 3.2 Functional Description On-Chip Memories As shown in the TC1764 block diagram on Page 2-6, some of the TC1764 units provide on-chip memories that are used as program or data memory. * * * * * * Program memory in PMU - 16 Kbyte Boot ROM (BROM) - 1 Mbyte Program Flash (PFlash) Program memory in PMI - 8 Kbyte Scratch-Pad RAM (SPRAM) - 8 Kbyte Instruction Cache (ICACHE) Data memory in PMU - 16 Kbyte Data Flash (DFlash) - 8 Kbyte Overlay RAM (OVRAM) Data memory in DMI - 40 Kbyte Local Data RAM (LDRAM) Memory of PCP2 - 12 Kbyte Code Memory (CMEM) with parity error protection - 8 Kbyte Parameter RAM (PRAM) with parity error protection On-chip SRAM with parity error protection.

The memory protection system controls the position and range of addressable segments in memory. It also controls the types of read and write operations allowed within addressable memory segments. Any illegal memory access is detected by the memory protection hardware, which then invokes the appropriate Trap Service Routine (TSR) to handle the error. Thus, the memory protection system protects critical system functions against both software and hardware errors. The memory protection hardware can also generate signals to the Debug Unit to facilitate tracing illegal memory accesses. There are two Memory Protection Register Sets in the TC1764, numbered 0 and 1, which specify memory protection ranges and permissions for code and data. The PSW.PRS bit field determines which of these is the set currently in use by the CPU. As the TC1764 uses a Harvard-style memory architecture, each Memory Protection Register Set is broken down into a Data Protection Register Set and a Code Protection Register Set. Each Data Protection Register Set can specify up to four address ranges to receive a particular protection modes. Each Code Protection Register Set can specify up to two address ranges to receive a particular protection modes. Each Data Protection Register Sets and Code Protection Register Sets determines the range and protection modes for a separate memory area. Each set contains a pair of registers which determine the address range (the Data Segment Protection Registers and Code Segment Protection Registers) and one register (Data Protection Mode Register) which determines the memory access modes that applies to the specified range. 3.5 Peripheral Control Processor The Peripheral Control Processor (PCP2) in the TC1764 performs tasks that would normally be performed by the combination of a DMA controller and its supporting CPU interrupt service routines in a traditional computer system. It could easily be considered as the host processor's first line of defence as an interrupt-handling engine. The PCP can unload the CPU from having to service time-critical interrupts. This provides many benefits, including: * * * * Avoiding large interrupt-driven task context-switching latencies in the host processor Reducing the cost of interrupts in terms of processor register and memory overhead Improving the responsiveness of interrupt service routines to data-capture and datatransfer operations Easing the implementation of multitasking operating systems The PCP2 has an architecture that efficiently supports DMA-type transactions to and from arbitrary devices and memory addresses within the TC1764 and also has reasonable stand-alone computational capabilities. Data Sheet 28 V1.0, 2008-04 TC1764 Preliminary Functional Description The PCP2 in the TC1764 contains an improved version of the TC1775's PCP with the following enhancements: * * * * * Optimized context switching Support for nested interrupts Enhanced instruction set Enhanced instruction execution speed Enhanced interrupt queueing The PCP2 is made up of several modular blocks as follows (see Figure 3-1): * * * * * * PCP Processor Core Code Memory (CMEM) Parameter Memory (PRAM) PCP Interrupt Control Unit (PICU) PCP Service Request Nodes (PSRN) System bus interface to the Flexible Peripheral Interface (FPI Bus) Code Memory CMEM Parameter Memory PRAM PCP Processor Core PCP Service Req.

One data move operation is controlled by one DMA channel. Eight DMA channels are provided in one DMA Sub-Block. The Bus Switch provides the connection of the DMA Sub-Block to the two FPI Bus interfaces and an MLI bus interface. In the TC1764, the FPI Bus interfaces are connected to the System Peripheral Bus and the DMA Bus. The third specific bus interface provides a connection to the Micro Link Interface module (MLI0 in the TC1764) and other DMA-related devices (Memory Checker module in the TC1764). Clock control, address decoding, DMA request wiring, and DMA interrupt service request control are implementation-specific and managed outside the DMA controller kernel. Figure 3-2 shows the implementation details and interconnections of the DMA module. fDMA DMA Sub-Block 0 DMA Requests of On-chip Periph.

Read/write requests of the System Bus side to the peripherals on DMA Bus are bridged to the DMA Bus (only the DMA is the master on the DMA bus), allowing easy access to these peripherals by PCP and CPU Memory Checker The Memory Checker Module (MCHK) makes it possible to check the data consistency of memories. Any SPB bus master may access the memory checker. It is preferable the DMA does it as described hereafter. It uses DMA 8-bit, 16-bit, or 32-bit moves to read from the selected address area and to write the value read in a memory checker input register. With each write operation to the memory checker input register, a polynomial checksum calculation is triggered and the result of the calculation is stored in the memory checker result register. The memory checker uses the standard Ethernet polynomial, which is given by: G32 = x32+ x26+ x23+ x22+ x16+ x12+ x11+ x10+ x8+ x7+ x5+ x4+ x2+ x +1 Note: Although the polynomial above is used for generation, the generation algorithm differs from the one that is used by the Ethernet protocol. Data Sheet 32 V1.0, 2008-04 TC1764 Preliminary 3.7 Functional Description Interrupt System The TC1764 interrupt system provides a flexible and time-efficient means of processing interrupts. An interrupt request can be serviced either by the CPU or by the Peripheral Control Processor (PCP). These units are called "Service Providers". Interrupt requests are called "Service Requests" rather than "Interrupt Requests" in this document because they can be serviced by either Service Providers. Each peripheral in the TC1764 can generate service requests. Additionally, the Bus Control Units, the Debug Unit, the PCP, and even the CPU itself can generate service requests to either of the two Service Providers. As shown in Figure 3-3, each TC1764 unit that can generate service requests is connected to one or multiple Service Request Nodes (SRN). Each SRN contains a Service Request Control Register mod_SRCx, where "mod" is the identifier of the service requesting unit and "x" an optional index. Two arbitration buses connect the SRNs with two Interrupt Control Units, which handle interrupt arbitration among competing interrupt service requests, as follows: * * The Interrupt Control Unit (ICU) arbitrates service requests for the CPU and administers the CPU Interrupt Arbitration Bus. The Peripheral Interrupt Control Unit (PICU) arbitrates service requests for the PCP and administers the PCP Interrupt Arbitration Bus. The PCP can make service requests directly to itself (via the PICU), or it can make service requests to the CPU. The Debug Unit can generate service requests to the PCP or the CPU. The CPU can make service requests directly to itself (via the ICU), or it can make service requests to the PCP. The CPU Service Request Nodes are activated through software. Depending on the selected system clock frequency fSYS, the number of fSYS clock cycles per arbitration cycle must be selected as follows: * * fSYS < 60 MHz: ICR.CONECYC = 1 and PCP_ICR.CONECYC = 1 fSYS > 60 MHz: ICR.CONECYC = 0 and PCP_ICR.CONECYC = 0 Data Sheet 33 V1.0, 2008-04 TC1764 Preliminary Functional Description PCP Interrupt Arbitration Bus Service Requestors CPU Interrupt Arbitration Bus Service Req.

TC1764 and other The ASC supports full-duplex asynchronous communication and half-duplex synchronous communication. In Synchronous Mode, data is transmitted or received synchronous to a shift clock that is generated by the ASC internally.

Parity, framing, and overrun error detection are provided to increase the reliability of data transfers. Transmission and reception of data is double-buffered. For multiprocessor communication, a mechanism is included to distinguish address bytes from data bytes. Testing is supported by a loop-back option. A 13-bit baud rate generator provides the ASC with a separate serial clock signal, which can be accurately adjusted by a prescaler implemented as fractional divider.

The serial clock signal can be generated by the SSC itself (Master Mode) or can be received from an external master (Slave Mode). Data width, shift direction, clock polarity and phase are programmable. This allows communication with SPI-compatible devices. Transmission and reception of data is double-buffered.

Eight output lines are required for the serial communication of the downstream channel (clock, data, and enable signals). One out of eight input lines SDI[7:0] is used as serial data input signal for the upstream channel. The source of the serial data to be transmitted by the downstream channel can be MSC register contents or data that is provided at the ALTINL/ALTINH input lines. These input lines are typically connected to other on-chip peripheral units (for example with a timer unit like the GPTA). An emergency stop input signal makes it possible to set bits of the serial data stream to dedicated values in emergency cases. Data Sheet 39 V1.0, 2008-04 TC1764 Preliminary Functional Description Clock control, address decoding, and interrupt service request control are managed outside the MSC module kernel.

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. Both 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 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 the message object list of the CAN node, and it transmits only messages belonging to this message object list. A powerful, command-driven list controller performs all message object list operations. The bit timings for the CAN nodes are derived from the module timer clock (fCAN), and are programmable up to a data rate of 1 Mbit/s. External bus transceivers are connected to a CAN node via a pair of receive and transmit pins.

Phase Discrimination Logic units (PDL) decode the direction information output by a rotation tracking system. Duty Cycle Measurement Cells (DCM) provide pulse-width measurement capabilities. A Digital Phase Locked Loop unit (PLL) generates a programmable number of GPTA module clock ticks during an input signal's period. Global Timer units (GT) driven by various clock sources are implemented to operate as a time base for the associated Global Timer Cells. Global Timer Cells (GTC) can be programmed to capture the contents of a Global Timer on an external or internal event. A GTC may also be used to control an external port pin depending on the result of an internal compare operation. GTCs can be logically concatenated to provide a common external port pin with a complex signal waveform. Local Timer Cells (LTC) operating in Timer, Capture, or Compare Mode may also be logically tied together to drive a common external port pin with a complex signal waveform. LTCs -- enabled in Timer Mode or Capture Mode -- can be clocked or triggered by various external or internal events. Input lines can be shared by an LTC and a GTC to trigger their programmed operation simultaneously. The following list summarizes the specific features of the GPTA unit.

The STM clock frequency is fSTM = fSYS/RMC with RMC = 0-7 (default after reset is fSTM = fSYS/2, selected by RMC = 010B). RMC is a bit field in register STM_CLC. In case of a power-on reset, a watchdog reset, or a software reset, the STM is reset. After one of these reset conditions, the STM is enabled and immediately starts counting up. It is not possible to affect the content of the timer during normal operation of the TC1764. The timer registers can only be read but not written to. The STM can be optionally disabled for power-saving purposes, or suspended for debugging purposes via its clock control register. In suspend mode of the TC1764 (initiated by writing an appropriate value to STM_CLC register), the STM clock is stopped but all registers are still readable. Due to the 56-bit width of the STM, it is not possible to read its entire content with one instruction. It needs to be read with two load instructions. Since the timer would continue to count between the two load operations, there is a chance that the two values read are not consistent (due to possible overflow from the low part of the timer to the high part between the two read operations). To enable a synchronous and consistent reading operation of the STM content, a capture register (STM_CAP) is implemented. It latches the content of the high part of the STM each time when one of the registers STM_TIM0 to STM_TIM5 is read. Thus, STM_CAP holds the upper value of the timer at exactly the same time when the lower part is read. The second read operation would then read the content of the STM_CAP to get the complete timer value. Data Sheet 53 V1.0, 2008-04 TC1764 Preliminary Functional Description The STM can also be read in sections from seven registers, STM_TIM0 through STM_TIM6, that select increasingly higher-order 32-bit ranges of the STM. These can be viewed as individual 32-bit timers, each with a different resolution and timing range. The content of the 56-bit System Timer can be compared with the content of two compare values stored in the STM_CMP0 and STM_CMP1 registers. Interrupts can be generated on a compare match of the STM with the STM_CMP0 or STM_CMP1 registers. The maximum clock period is 256 x fSTM. At fSTM = 80 MHz, for example, the STM counts 28.56 years before overflowing. Thus, it is capable of timing the entire expected product life-time of a system without overflowing continuously. Figure 3-13 shows an overview on the System Timer with the options for reading parts of the STM contents.

The WDT helps to abort an accidental malfunction of the TC1764 in a user-specified time period. When enabled, the WDT will cause the TC1764 system to be reset if the WDT is not serviced within a user-programmable time period. The CPU must service the WDT within this time interval to prevent the WDT from causing a TC1764 system reset. Hence, routine service of the WDT confirms that the system is functioning as expected. In addition to this standard "Watchdog" function, the WDT incorporates the End-ofInitialization (Endinit) feature and monitors its modifications. A system-wide line is connected to the WDT_CON0.ENDINIT bit, serving as an additional write-protection for critical registers (besides Supervisor Mode protection). Registers protected via this line can only be modified when Supervisor Mode is active and bit ENDINIT = 0. A further enhancement in the TC1764's WDT is its reset prewarning operation. Instead of resetting the device upon the detection of an error immediately (the way that standard Watchdogs do), the WDT first issues a Non-Maskable Interrupt (NMI) to the CPU before resetting the device at a specified time period later. This step gives the CPU a chance to save the system state to the memory for later investigation of the cause of the malfunction; an important aid in debugging. Features * * * * * * * * * * 16-bit Watchdog counter Selectable input frequency: fSYS/256 or fSYS/16384 16-bit user-definable reload value for normal Watchdog operation, fixed reload value for Time-Out and Prewarning Modes Incorporation of the ENDINIT bit and monitoring of its modifications Sophisticated Password Access mechanism with fixed and user-definable password fields Proper access always requires two write accesses. The time between the two accesses is monitored by the WDT and is limited. Access Error Detection: Invalid password (during first access) or invalid guard bits (during second access) trigger the Watchdog reset generation Overflow Error Detection: An overflow of the counter triggers the Watchdog reset generation. Watchdog function can be disabled; access protection and ENDINIT monitor function remain enabled. Double Reset Detection: If a Watchdog induced reset occurs twice, a severe system malfunction is assumed and the TC1764 is held in reset until a power-on or hardware reset occurs. This prevents the device from being periodically reset if, for instance, connection to the external memory has been lost such that system initialization could not even be performed. Data Sheet 56 V1.0, 2008-04 TC1764 Preliminary * Functional Description Important debugging support is provided through the reset prewarning operation by first issuing an NMI to the CPU before finally resetting the device after a certain period of time. 3.18 System Control Unit The System Control Unit (SCU) of the TC1764 handles several system control tasks. The system control tasks of the SCU are: * * * * * * * * * * * * * * Clock system selection and control Reset and boot operation control Power management control Configuration input sampling External Request Unit System clock output control On-chip SRAM parity control Pad driver temperature compensation control Emergency stop input control for GPTA outputs GPTA input IN1 control Pad test mode control for dedicated pins ODCS level 2 trace control NMI control Miscellaneous SCU control Data Sheet 57 V1.0, 2008-04 TC1764 Preliminary 3.19 Functional Description Boot Options The TC1764 booting schemes provide a number of different boot options for the start of code execution. Table 3-3 shows the boot options available in the TC1764.

For more details on ABM, see the User's Manual. Data Sheet 58 V1.0, 2008-04 TC1764 Preliminary 3.20 Functional Description Power Management System The TC1764 power management system allows software to configure the various processing units so that they automatically adjust to draw the minimum necessary power for the application. There are three power management modes: * * * Run Mode Idle Mode Sleep Mode The operation of each system component in each of these states can be configured by software. The power-management modes provide flexible reduction of power consumption through a combination of techniques, including stopping the CPU clock, stopping the clocks of other system components individually, and individually clockspeed reduction of some peripheral components. Besides these explicit software-controlled power-saving modes, special attention has been paid to automatic power-saving in those operating units which are not required at a certain point of time, or idle in the TC1764. In that case, they are shut off automatically until their operation is required again. Table 3-4 describes the features of the power management modes. Table 3-4 Power Management Mode Summary Mode Description Run The system is fully operational. All clocks and peripherals are enabled, as determined by software. Idle The CPU clock is disabled, waiting for a condition to return it to Run Mode. Idle Mode can be entered by software when the processor has no active tasks to perform. All peripherals remain powered and clocked. Processor memory is accessible to peripherals. A reset, Watchdog Timer event, a falling edge on the NMI pin, or any enabled interrupt event will return the system to Run Mode. Sleep The system clock signal is distributed only to those peripherals programmed to operate in Sleep Mode. The other peripheral module will be shut down by the suspend signal. Interrupts from operating peripherals, the Watchdog Timer, a falling edge on the NMI pin, or a reset event will return the system to Run Mode. Entering this state requires an orderly shut-down controlled by the Power Management State Machine. In typical operation, Idle Mode and Sleep Mode may be entered and exited frequently during the run time of an application. For example, system software will typically cause the CPU to enter Idle Mode each time it has to wait for an interrupt before continuing its tasks. In Sleep Mode and Idle Mode, wake-up is performed automatically when any Data Sheet 59 V1.0, 2008-04 TC1764 Preliminary Functional Description enabled interrupt signal is detected, or when the count value (WDT_SR.WDTTIM) changes from 7FFFH to 8000H. 3.21 On-Chip Debug Support Figure 3-14 shows a block diagram of the TC1764 OCDS system.

The OCDS Level 1 is based on a JTAG interface that is used by the external debug hardware to communicate with the system. The on-chip Cerberus module controls the interactions between the JTAG interface and the on-chip modules. The external debug hardware may become master of the internal buses, and read or write the on-chip register/memory resources. The Cerberus also makes it possible to define breakpoint and trigger conditions as well as to control user program execution (run/stop, break, single-step). OCDS Level 2 Debug Support The OCDS Level 2 debug support makes it possible to implement program tracing capabilities for enhanced debuggers by extending the OCDS Level 1 debug functionality with an additional 16-bit wide trace output port with trace clock. With the trace extension, the following four trace capabilities are provided (only one of the four trace capabilities can be selected at a time): * * * * Trace of the CPU program flow Trace of the PCP2 program flow Trace of the DMA Controller transaction requests Trace of the DMA Controller Move Engine status information OCDS Level 3 Debug Support The OCDS Level 3 debug support is based on a special TC1766 emulation device, the TC1766ED, which provides additional features required for high-end emulation purposes. The TC1766ED is a device which includes the TC1766 product chip and additional emulation extension hardware in a package with the same footprint as the TC1766. Data Sheet 61 V1.0, 2008-04 TC1764 Preliminary 3.22 Functional Description Clock Generation and PLL The TC1764 clock system performs the following functions: * * * * * * Acquires and buffers incoming clock signals to create a master clock frequency Distributes in-phase synchronized clock signals throughout the TC1764's entire clock tree Divides a system master clock frequency into lower frequencies required by the different modules for operation. Dynamically reduces power consumption during operation of functional units Statically reduces power consumption through programmable power-saving modes Reduces electromagnetic interference (EMI) by switching off unused modules The clock system must be operational before the TC1764 can function, so it contains special logic to handle power-up and reset operations. Its services are fundamental to the operation of the entire system, so it contains special fail-safe logic. Features * * * * PLL operation for multiplying clock source by different factors Direct drive capability for direct clocking Comfortable state machine for secure switching between basic PLL, direct or prescaler operation Sleep and Power-Down Mode support The TC1764 Clock Generation Unit (CGU) as shown in Figure 3-15 allows a very flexible clock generation. It basically consists of an main oscillator circuit and a PhaseLocked Loop (PLL). The PLL can converts a low-frequency external clock signal from the oscillator circuit to a high-speed internal clock for maximum performance. The system clock fSYS is generated from an oscillator clock fOSC in either one of the four hardware/software selectable ways: * * * * Direct Drive Mode (PLL Bypass): In Direct Drive Mode, the TC1764 clock system is directly driven by an external clock signal. input, i.e. fCPU = fOSC and fSYS = fOSC. This allows operation of the TC1764 with a reasonably small fundamental mode crystal. VCO Bypass Mode (Prescaler Mode): In VCO Bypass Mode, fCPU and fSYS are derived from fOSC by the two divider stages, P-Divider and K-Divider. The system clock fSYS is equal to fCPU. PLL Mode: In PLL Mode, the PLL is running. The VCO clock fVCO is derived from fOSC, divided by the P factor, multiplied by the PLL (N-Divider). The clock signals fCPU and fSYS are derived from fVCO by the K-Divider. The system clock fSYS is equal to fCPU. PLL Base Mode: In PLL Base Mode, the PLL is running at its VCO base frequency and fCPU and fSYS Data Sheet 62 V1.0, 2008-04 TC1764 Preliminary Functional Description are derived from fVCO only by the K-Divider. In this mode, the system clock fSYS is equal to fCPU. XTAL1 Clock Generation Unit (CGU) Oscillator Circuit fOSC 1:1 Divider 1 XTAL2 Osc. Run Detect.

It basically consists of an inverting amplifier and a feedback element with XTAL1 as input, and XTAL2 as output. When using a crystal, a proper external oscillator circuitry must be connected to both pins, XTAL1 and XTAL2. The crystal frequency can be within the range of 4 MHz to 25 MHz. Additionally, it is necessary to have two load capacitances CX1 and CX2, and depending on the crystal type, a series resistor RX2, to limit the current. A test resistor RQ may be temporarily inserted to measure the oscillation allowance (negative resistance) of the oscillator circuitry. RQ values are typically specified by the crystal vendor. The CX1 and CX2 values shown in Figure 3-16 can be used as starting points for the negative resistance evaluation and for non-productive systems. The exact values and related operating range are dependent on the crystal frequency and have to be determined and optimized together with the crystal vendor using the negative resistance method. Data Sheet 63 V1.0, 2008-04 TC1764 Preliminary Functional Description Oscillation measurement with the final target system is strongly recommended to verify the input amplitude at XTAL1 and to determine the actual oscillation allowance (margin negative resistance) for the oscillator-crystal system. When using an external clock signal, the signal must be connected to XTAL1. XTAL2 is left open (unconnected). The external clock frequency can be in the range of 0 - 40 MHz if the PLL is bypassed, and 4 - 40 MHz if the PLL is used. The oscillator can also be used in combination with a ceramic resonator. The final circuitry must also be verified by the resonator vendor. Figure 3-16 shows the recommended external oscillator circuitries for both operating modes, external crystal mode and external input clock mode. A block capacitor is recommended to be placed between VDDOSC/VDDOSC3 and VSSOSC.

VAREF = ( VDDM + 0.05 V to 5) If a reduced reference voltage in a range of VDDM/2 to VDDM is used, then the ADC converter errors increase. If the reference voltage is reduced with the factor k (k<1), then TUE, DNL, INL Gain and Offset errors increase with the factor 1/k. If a reduced reference voltage in a range of 1 V to VDDM/2 is used, then there are additional decrease in the ADC speed and accuracy. 6) Current peaks of up to 6 mA with a duration of max. 2 ns may occur 7) TUE is tested at VAREF = 3.3 V, VAGND = 0 V and VDDM = 3.3 V 8) ADC module capability. 9) Not subject to production test, verified by design / characterization. 10) Value under typical application conditions due to integration (switching noise, etc.). 11) The sum of DNL/INL/Gain/Offset errors does not exceed the related TUE total unadjusted error. 12) For 10-bit conversions the DNL/INL/Gain/Offset error values must be multiplied with factor 0.25. For 8-bit conversions the DNL/INL/Gain/Offset error values must be multiplied with 0.0625. 13) The leakage current definition is a continuous function, as shown in Figure 4-3. The numerical values defined determine the characteristic points of the given continuous linear approximation - they do not define step function. 14) Only one of these parameters is tested, the other is verified by design characterization. Data Sheet 79 V1.0, 2008-04 TC1764 Preliminary Electrical Parameters 15) IAREF_MAX is valid for the minimum specified conversion time. The current flowing during an ADC conversion with a duration of up to tC = 25s can be calculated with the formula IAREF_MAX = QCONV/tC. Every conversion needs a total charge of QCONV = 150pC from VAREF. All ADC conversions with a duration longer than tC = 25s consume an IAREF_MAX = 6A. 16) For the definition of the parameters see also Figure 4-2. 17) Applies to AIN0 and AIN1, when used as auxiliary reference inputs. 18) This represents an equivalent switched capacitance. This capacitance is not switched to the reference voltage at once. Instead of this smaller capacitances are successively switched to the reference voltage. 19) The sampling capacity of the conversion C-Network is pre-charged to VAREF/2 before the sampling moment. Because of the parasitic elements the voltage measured at AINx is lower then VAREF/2.

Phase Locked Loop Operation When PLL operation is enabled and configured, the PLL clock fVCO (and with it the CPU clock fCPU) is constantly adjusted to the selected frequency. The relation between fVCO and fSYS is defined by: fVCO = K x fCPU. The PLL causes a jitter of fCPU and affects the clock outputs TRCLK and SYSCLK (P4.3) which are derived from the PLL clock fVCO. There are two formulas that define the (absolute) approximate maximum value of jitter DP in ns dependent on the K-factor, the CPU clock frequency fCPU in MHz, and the number P of consecutive fCPU clock periods. P x K < 900 5xP Dp [ ns ] = ----------------------------+ 0, 9 fcpu [ MHz ] (4.1) P x K 900 4500 Dp [ ns ] = --------------------------------------- + 0, 9 fcpu [ MHz ] x K (4.2) K : K-Divider Value P : Number of fCPU periods DP : Jitter in ns fCPU : CPU frequency in MHz Data Sheet 96 V1.0, 2008-04 TC1764 Preliminary Electrical Parameters Note: The frequency of system clock fSYS can be selected to be either fCPU or fCPU/2. With rising number P of clock cycles the maximum jitter increases linearly up to a value of P that is defined by the K-factor of the PLL. Beyond this value of P the maximum accumulated jitter remains at a constant value. Further, a lower CPU clock frequency fCPU results in a higher absolute maximum jitter value. Figure 4-12 illustrates the jitter curve for several K/ fCPU combinations.

Unit Notes Thermal resistance junction case top1) RTJCT CC - 5.4 K/W - Thermal resistance junction leads1) RTJL - 21.5 K/W - CC 1) The thermal resistances between the case top and the ambient (RTCAT), the leads and the ambient (RTLA) are to be combined with the thermal resistances between the junction and the case top (RTJCT ), the junction and the leads (RTJL) given above, in order to calculate the total thermal resistance between the junction and the ambient (RTJA). The thermal resistances between the case top and the ambient (RTCAT ), the leads and the ambient (RTLA) depend on the external system (PCB, case) characteristics, and are under user responsibility. The junction temperature can be calculated using the following equation: TJ=TA+RTJA x PD, where the RTJA is the total thermal resistance between the junction and the ambient. This total junction ambient resistance RTJA can be obtained from the upper four partial thermal resistances.
