In addition, the state of the port pins are
latched into the software configuration input
register SCU_SCLIR at the rising edge of
HDRST. Therefore, Port 0 pins can be used
for operating mode selections by software.

1) These pads are I/O pads with input only function. Its input characteristics are identical with the input
characteristics as defined for class A pads.
2) In case of a power-fail condition (one or more power supply voltages drop below the specified voltage range),
an undefined output driving level may occur at these pins.
3) Programmed by software as either break input or break output.
4) These pads are input only pads with input characteristics.
5) Input only pads with input spike filter.
6) Open drain pad with input spike filter.
7) The dual input reset system of TC1762/TC1766ED, assumes that the PORST reset pin is used for power-on
reset only. It has to be taken into account that if a system uses the PORST reset input for other system resets,
the emulation part of the TC1766ED Emulation Device is reset as well. Thus, it will always force a complete
re-initialization of the emulator and will prevent the user debugging across these types of resets.
8) Input only pads without input spike filter.

Functional Description
Chapter 3 provides an overview of the TC1762 functional description.
3.1
System Architecture and On-Chip Bus Systems
The TC1762 has two independent on-chip buses (see also TC1762 block diagram on
Page 2-6):
• Local Memory Bus (LMB)
• System Peripheral Bus (SPB)
The LMB Bus connects the CPU local resources for data and instruction fetch. 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 accessible to the CPU via the LMB Bus bridge. The System Peripheral
Bus (SPB Bus) in TC1762 is an on-chip FPI Bus. The FPI Bus interconnects the
functional units of the TC1762, 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. With a 66 MHz
bus clock, the peak transfer rate is up to 264 Mbytes/s. 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 66 or 80 MHz depending on the derivative.
Additionally, two simplified bus interfaces are connected to and controlled by the DMA
Controller:
• DMA Bus
• SMIF Interface

Memory Protection System
The TC1762 memory protection system specifies the addressable range and read/write
permissions of memory segments available to the current executing task. 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 TC1762, 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 TC1762 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.

DMA Controller and Memory Checker
The DMA Controller of the TC1762 transfers data from data source locations to data
destination locations without intervention of the CPU or other on-chip devices. 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 TC1762, 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 TC1762) and other DMA-related devices (Memory Checker module in the TC1762).
Clock control, address decoding, DMA request wiring, and DMA interrupt service request
control are implementation-specific and managed outside the DMA controller kernel.
Figure 3-1 shows the implementation details and interconnections of the DMA module.

– 2-level programmable priority of DMA channels within the DMA Sub-Block
– Software and hardware DMA request
– Hardware requests by selected on-chip peripherals and external inputs
• Programmable priority of the DMA Sub-Blocks on the bus interfaces
• Buffer capability for move actions on the buses (at least 1 move per bus is buffered).
• Individually programmable operation modes for each DMA channel
– Single Mode: stops and disables DMA channel after a predefined number of DMA
transfers
– Continuous Mode: DMA channel remains enabled after a predefined number of
DMA transfers; DMA transaction can be repeated.
– Programmable address modification
• Full 32-bit addressing capability of each DMA channel
– 4 Gbyte address range
– Support of circular buffer addressing mode
• Programmable data width of DMA transfer/transaction: 8-bit, 16-bit, or 32-bit
• Micro Link bus interface support
• Register set for each DMA channel
– Source and destination address register
– Channel control and status register
– Transfer count register
• Flexible interrupt generation (the service request node logic for the MLI channels is
also implemented in the DMA module)
• All buses connected to the DMA module must work at the same frequency.
• 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 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.

Interrupt System
The TC1762 interrupt system provides a flexible and time-efficient means of processing
interrupts. An interrupt request is serviced by the CPU, which is called the “Service
Provider”. Interrupt requests are called “Service Requests” rather than “Interrupt
Requests” in this document.
Each peripheral in the TC1762 can generate service requests. Additionally, the Bus
Control Units, the Debug Unit, and even the CPU itself can generate service requests to
the Service Provider.
As shown in Figure 3-2, each TC1762 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. The CPU Interrupt Arbitration Bus
connects the SRNs with the Interrupt Control Unit (ICU), which arbitrates service
requests for the CPU and administers the CPU Interrupt Arbitration Bus.
The Debug Unit can generate service requests to the CPU. The CPU makes service
requests directly to itself (via the ICU). 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
• fSYS > 60 MHz: ICR.CONECYC = 0

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

Block Diagram of MultiCAN Module
The MultiCAN module contains two independently-operating CAN nodes with Full-CAN
functionality that 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.
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.

The General Purpose Timer Array GPTA0 provides a set of hardware modules required
for high-speed digital signal processing:
• Filter and Prescaler Cells (FPC) support input noise filtering and prescaler operation.
• 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 ADC module has 16 analog input channels. An analog multiplexer selects the input
line for the analog input channels from among 32 analog inputs. Additionally, an external
analog multiplexer can be used for analog input extension. External Clock control,
address decoding, and service request (interrupt) control are managed outside the ADC
module kernel. External trigger conditions are controlled by an External Request Unit.
This unit generates the control signals for auto-scan control (ASGT), software trigger
control (SW0TR, SW0GT), the event trigger control (ETR, EGT), queue control (QTR,
QGT), and timer trigger control (TTR, TGT).
An automatic self-calibration adjusts the ADC module to changing temperatures or
process variations. Figure 3-10 shows the global view of the ADC module with its

System Timer
The TC1762’s STM is designed for global system timing applications requiring both high
precision and long period.
Features
• Free-running 56-bit counter
• All 56 bits can be read synchronously
• Different 32-bit portions of the 56-bit counter can be read synchronously
• Flexible interrupt generation based on compare match with partial STM content
• Driven by maximum 66 or 80 MHz (= fSYS, default after reset = fSYS/2) depending on
derivative
• Counting starts automatically after a reset operation
• STM is reset by:
– Watchdog reset
– Software reset (RST_REQ.RRSTM must be set)
– Power-on reset
• STM (and clock divider STM_CLC.RMC) is not reset at a hardware reset (HDRST =
0)
• STM can be halted in debug/suspend mode (via STM_CLC register)
The STM is an upward counter, running either at the system clock frequency fSYS or at a
fraction of it. 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 TC1762.
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 TC1762
(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
Data Sheet
51
V1.0, 2008-04
TC1762
Preliminary
Functional Description
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.
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 × 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 3-12 shows an overview on the System Timer with the options for reading parts
of the STM contents.

Watchdog Timer
The WDT provides a highly reliable and secure way to detect and recover from software
or hardware failure. The WDT helps to abort an accidental malfunction of the TC1762 in
a user-specified time period. When enabled, the WDT will cause the TC1762 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
TC1762 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-of-
Initialization (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 TC1762’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 TC1762 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.

Power Management System
The TC1762 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 clock-
speed 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 TC1762. In that case, they are shut off automatically
until their operation is required again.
Table 3-3 describes the features of the power management modes.
Table 3-3
Mode
Power Management Mode Summary
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

Functional Description
OCDS Level 1 Debug Support
The OCDS Level 1 debug support is mainly assigned for real-time software debugging
purposes which have a demand for low-cost standard debugger hardware.
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 three trace capabilities
can be selected at a time):
• Trace of the CPU 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.

Clock Generation and PLL
The TC1762 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 TC1762’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 TC1762 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 TC1762 Clock Generation Unit (CGU) as shown in Figure 3-14 allows a very
flexible clock generation. It basically consists of an main oscillator circuit and a Phase-
Locked 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 TC1762 clock system is directly driven by an external clock
signal. input, i.e. fCPU = fOSC and fSYS = fOSC. This allows operation of the TC1762 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:

Recommended Oscillator Circuits
The oscillator circuit, a Pierce oscillator, is designed to work with both, an external crystal
oscillator or an external stable clock source. 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 3-15 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
61
V1.0, 2008-04
TC1762
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 3-15 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
.

1) Digital supply voltages applied to the TC1762 must be static regulated voltages which allow a typical voltage
swing of ±5%.
2) Voltage overshoot up to 1.7 V is permissible at Power-Up and PORST low, provided the pulse duration is less
than 100 µs and the cumulated summary of the pulses does not exceed 1 h.
3) Voltage overshoot to 4 V is permissible at Power-Up and PORST low, provided the pulse duration is less than
100 µs and the cumulated summary of the pulses does not exceed 1 h.
4) The TC1762 uses a static design, so the minimum operation frequency is 0 MHz. Due to test time restriction
no lower frequency boundary is tested, however.
5) The PLL jitter characteristics add to this value according to the application settings. See the PLL jitter
parameters.
6) Applicable for digital outputs.
7) See additional document “TC1796 Pin Reliability in Overload“ for overload current definitions.

1) Voltage overshoot to 4 V are permissible, provided the pulse duration is less than 100 µs and the cumulated
summary of the pulses does not exceed 1 h.
2) Voltage overshoot to 1.7 V are permissible, provided the pulse duration is less than 100 µs and the cumulated
summary of the pulses does not exceed 1 h.
3) A running conversion may become inexact in case of violating the normal operating conditions (voltage
overshoot).
4) If the reference voltage VAREF increases or the VDDM decreases, so that VAREF = ( VDDM + 0.05 V to
V
DDM + 0.07 V), then the accuracy of the ADC decreases by 4LSB12.
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.

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 = 25µs 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 = 25µs consume an IAREF_MAX = 6µA.
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.

1) Calibration of the gain is possible for the gain of 1 and 2, and not possible for the gain of 4 and 8.
2) Calibration should be performed at each power-up. In case of continuous operation, calibration should be
performed minimum once per week.
3) The offset error voltage drifts over the whole temperature range typically ±2 LSB.
4) Applies when the gain of the channel equals one. For the other gain settings, the offset error increases; it must
be multiplied with the applied gain.
5) The leakage current definition is a continuous function, as shown in Figure 4-5. The numerical values defined
determine the characteristic points of the given continuous linear approximation - they do not define step
function.
6) Only one of these parameters is tested, the other is verified by design characterization.
7) Voltage overshoot to 4 V are permissible, provided the pulse duration is less than 100 µs and the cumulated
summary of the pulses does not exceed 1 h.
8) Voltage overshoot to 1.7 V are permissible, provided the pulse duration is less than 100 µs and the cumulated
sum of the pulses does not exceed 1 h.
9) A running conversion may become inexact in case of violating the normal operating conditions (voltage
overshoots).

All ground pins VSS must be externally connected to one single star point in the system.
The difference voltage between the ground pins must not exceed 200 mV.
The PORST signal must be activated at latest before any power supply voltage falls
below the levels shown on the figure below. In this case, only the memory row of a Flash
memory that was the target of the write at the moment of the power loss will contain
unreliable content. Additionally, the PORST signal should be activated as soon as
possible. The sooner the PORST signal is activated, the less time the system operates
outside of the normal operating power supply range.

3) Any HDRST activation is internally prolonged to 1024 FPI bus clock (fSYS) cycles.
4) Applicable for input pins TESTMODE, TRST, BRKIN, and TXD1A with noise suppression filter of PORST

8) Not subject to production test, verified by design / characterization.
9) In case of power loss during internal flash write, prevents Flash write to random address.
10) Booting from Flash, the duration of the boot-time is defined between the rising edge of the PORST and the
moment when the first user instruction has entered the CPU and its processing starts.
11) Booting from Flash, the duration of the boot time is defined between the following events:
1. Hardware reset: the falling edge of a short HDRST pulse and the moment when the first user instruction has
entered the CPU and its processing starts, if the HDRST pulse is shorter than 1024 × TSYS
.
If the HDRST pulse is longer than 1024 × TSYS, only the time beyond the 1024 × TSYS should be added to the
boot time (HDRST falling edge to first user instruction).
2. Software reset: the moment of starting the software reset and the moment when the first user instruction
has entered the CPU and its processing starts

1) The CPU base frequency which is selected after reset is calculated by dividing the limit values by 16 (this is
the K factor after reset).
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 × 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.

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 for several K/ fCPU combinations.

Note: The maximum peak-to-peak noise on the main oscillator and PLL power supply
(measured between VDDOSC and VSSOSC) is limited to a peak-to-peak voltage of
VPP = 10 mV. This condition can be achieved by appropriate blocking to the supply
pins and using PCB supply and ground planes.

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 × 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.
