SPC574Sx

Introduction

eTimer

Has six 16-bit general purpose counters, where each counter can be used as an

input capture or output compare function

FCCU

Collects fault event notifications from the rest of the system and translates them

into internal and/or external system reactions

RCCU

Compares input signals and issues an alarm in the case of a mismatch

MEMU

Collects and reports error events associated with ECC (Error Correction Code)

logic used on SRAM, DMA RAM and Flash memory

XBIC

Verifies the integrity of the attribute information for crossbar transfers and

signals the Fault Collection and Control Unit (FCCU) when an error is detected

STCU2

Handles the BIST procedure

CRC

Controls the computation of CRC, off-loading this work from the CPU

RegProt

Protects several registers against accidental writing, locking their value till the

next reset phase

Temperature sensor

Monitors the device temperature

Debug Control Interface

Provides debug features for the MCU

Nexus Port Controller

Monitors a variety of signals including addresses, data, control signals, status

signals, etc.

Nexus Multimaster Trace Client

Monitors the system bus and provides real-time trace information to debug or

development tools

Periodic interrupt timer (PIT)

Produces periodic interrupts and triggers

System integration unit (SIUL)

Provides control over all the electrical pad controls and up to 32 ports with 16

bits of bidirectional, general-purpose input and output signals and supports up

to 32 external interrupts with trigger event configuration

System status configuration

module (SSCM)

Provides system configuration and status data (such as memory size and

status, device mode and security status), device identification data, debug

status port enable and selection, and bus and peripheral abort enable/disable

System timer module (STM)

Provides a set of output compare events to support AUTOSAR and operating

system tasks

System watchdog timer (SWT)

Provides protection from runaway code

Wakeup unit (WKPU)

The wakeup unit supports up to 18 external sources that can generate interrupts

or wakeup events, of which one can cause non-maskable interrupt requests or

wakeup events.

Crossbar (XBAR) switch

Supports simultaneous connections between two master ports and three slave

ports. The crossbar supports a 32-bit address bus width and a 64-bit data bus

width.

Decorated Storage Memory

Controller (DSMC)

Decorated Storage Memory Controller

CMU

Used to validate the target clock within a specific frequency range and to

measure the clock frequency.

Power Management Controller

(MC_PMC)

Contains registers that enable/disable the various voltage monitors
