Safety Application Guide for SPC563Mxx family

Introduction

This document contains guidelines in order to configure and use the SPC563Mxx device for

safety relevant applications. These guidelines are preceded by one of the following bold text

statements:

•

Suggested

Implementation hint

Rationale

These guidelines are useful approaches for the specific topics under discussion even if they

are not mandatory. The user needs to use discretion in deciding whether these measures

are appropriate for their applications.

This document is valid only under the assumption that the MCU is used in automotive

applications for use cases requiring a fail-safe MCU and if the environmental conditions

specified in the SPC563Mxx device data sheet are maintained.

Together with the standard documentation as the reference manual and the datasheet, also

SPC563Mxx device errata sheet must be taken into account during system design and

implementation (see

Chapter Appendix B: Document references).
