Application note

Developing self tests for SPC564Ax

Introduction

SPC564Ax devices have been designed for Powertrain applications like engine control and

transmission.

As these safety applications increasingly need to conform to safety standards like IEC51608

or ISO26262, there is a focus on self tests possible on each of the components of these

ECUs, including the microcontroller.

This application note shows how to define and design self tests for SPC564Ax. After an

introduction to self tests, the application note is focused initially on self tests for the CPU

subsystem, then on those on digital peripherals and finally on those on analog peripherals.
