About this manual

This document provides guidance on how to implement power-on self-test features for the SPC56EL60 system-on-chip (SoC) designed for safety-critical automotive applications. It focuses on minimizing software measures within the CPU core subsystem while ensuring latent faults are detected and managed during the MCU startup procedure.

The note details specific software requirements for various non-applicative peripherals, including the System Status and Configuration Module (SSCM), Self Test Control Unit (STCU), Redundancy Control Checker Unit (RCCU), Reset Generation Module (MC_RGM), Fault Collection and Control Unit (FCCU), Clock Monitor Unit (CMU), Flash memory integrity checks, Temperature Sensors, Software Watchdog Timer (SWT), Power Management Unit (PMU), and Analog to Digital Converter (ADC). It also covers applicative peripherals like the ADC self-test algorithms.
