Introduction
The CRC unit has the following features:
1.5.36
The RCCU checks all outputs of the sphere of replication (addresses, data, control signals). It has the following features:
1.5.37
The junction temperature sensor provides a value via an ADC channel that can be used by software to calculate the device
junction temperature.
The key parameters of the junction temperature sensor include:
1.5.38
The NPC module provides real-time development support capabilities for this device in compliance with the IEEE-ISTO
5001-2003. This development support is supplied for MCUs without requiring external address and data pins for internal
visibility.
The NPC block interfaces to the host processor and internal buses to provide development support as per the IEEE-ISTO
5001-2003 Class 3+, including selected features from Class 4 standard.
The development support provided includes program trace, data trace, watchpoint trace, ownership trace, run-time access to the
MCUs internal memory map and access to the Power Architecture internal registers during halt. The Nexus interface also
supports a JTAG only mode using only the JTAG pins. The following features are implemented:
1. 4 MDO pins on 144 LQFP package, 12 MDO pins on 257 MAPBGA package.

3 sets of registers to allow 3 concurrent contexts with possibly different CRC computations, each with a selectable
polynomial and seed
Computes 16- or 32-bit wide CRC on the fly (single-cycle computation) and stores result in internal register.
The following standard CRC polynomials are implemented:
— x
— x
— x
Key engine to be coupled with communication periphery where CRC application is added to allow implementation of
safe communication protocol
Offloads core from cycle-consuming CRC and helps checking configuration signature for safe start-up or periodic
procedures
CRC unit connected as peripheral bus on internal peripheral bus
DMA support
Duplicated module to guarantee highest possible diagnostic coverage (check of checker)
Multiple times replicated IPs are used as checkers on the SoR outputs
Nominal temperature range from –40 to 150 °C
Software temperature alarm via analog ADC comparator possible
Full and reduced port modes
MCKO (message clock out) pin
4 or 12 MDO (message data out) pins
2 MSEO (message start/end out) pins
EVTO (event out) pin
[32-bit CRC-ethernet(32)]
Redundancy Control and Checker Unit (RCCU)
Junction temperature sensor
Nexus Port Controller (NPC)
