1 Introduction

This document is a functional safety manual for the Texas Instrument MSPM0L component. The part numbers supported by this functional safety manual are as follows:

  • MSPM0L130x-Q1

This functional safety manual provides information needed by system developers to help in the creation of a functional safety system using a MSPM0L component. This document includes:

  • An overview of the component architecture
  • An overview of the development process used to decrease the probability of systematic failures
  • An overview of the functional safety architecture for management of random failures
  • The details of architecture partitions and implemented functional safety mechanisms

The following information is documented in the [Functional Safety Analysis Report] and is not repeated in this document:

  • Summary of failure rates (FIT) of the component
  • Summary of functional safety metrics of the hardware component for targeted standards (for example IEC 61508, ISO 26262, and so forth)
  • Quantitative functional safety analysis (also known as FMEDA, Failure Modes, Effects, and Diagnostics Analysis) with detail of the different parts of the component, allowing for customized application of functional safety mechanisms
  • Assumptions used in the calculation of functional safety metrics

The following information is documented in the [Functional Safety Report], and is not repeated in this document:

  • Results of assessments of compliance to targeted standards

The user of this document should have a general familiarity with the MSPM0L component. For more information, refer to the data sheet. This document is intended to be used in conjunction with the pertinent data sheets, technical reference manuals, and other component documentation.
