ISO 26262 Automotive Functional Safety Support
Designing safe and reliable automotive applications to enable passenger safety is critical. To meet these rigorous safety requirements, we offer a broad portfolio of functional safety-supported 32-bit microcontrollers (MCUs) that include the latest hardware safety features and all the safety collateral to help achieve ISO 26262 Automotive Safety Integrity Level (ASIL) B safety certification.
Our 32-bit MCUs are used as a Safety Element out of Context (SEooC). Our Functional Safety Manual has all the Assumptions of Use (AoUs) to use these devices safely.
You can also achieve higher levels of safety with ASIL Decomposition as described below.
32-bit MCU Functional Safety Support and Collateral
Our AEC-Q100 Grade 1- and Grade 2-qualified 32-bit MCUs come with the following resources to simplify safety certification of your automotive designs:
- TÜV Rheinland-certified safety diagnostic libraries for designs targeting up to ASIL B
- SGS TÜV Saar ASIL B Ready-Certified Failure Modes, Effects and Diagnostic Analysis (FMEDA) report and Functional Safety Manual (FSM)
- SGS TÜV Saar Part 11 Functional Safety Capable Certification
- Safety collateral, including pin FMEA, FMEDA, DFMEA, Functional Safety Manual, Dependent Failure Analysis (DFA) and Soft Error Rate Report
- Development ecosystem for functional safety applications with TÜV SÜD-certified MPLAB® XC32 compiler and a qualification package for the MPLAB development tool ecosystem
- ASIL B-compliant MCALs for AUTOSAR® applications
If you require any of the above collateral or have any questions, please email us or contact your local sales office.

Functional Safety Ecosystem
When you are designing functional safety applications, using development tools that meet the requirements of safety standards can make it easier for you to create compliant systems. To help you with implementing system-level functional safety in your applications, our MPLAB XC C compilers are TÜV SÜD-certified for several functional safety standards. We also provide the complete certification packages for our MPLAB development tools ecosystem to help you qualify your projects.
MPLAB X IDE
Organize, write, test and debug your embedded software applications in MPLAB X IDE.
MPLAB XC Compiler
Build your embedded software with the TÜV SÜD-certified MPLAB XC32 Pro Functional Safety Compiler.
MPLAB Code Coverage
Verify and document your software test coverage with the MPLAB Code Coverage tool.
Achieving ASIL C and ASIL D Safety Levels
You can typically achieve higher safety levels through ASIL decomposition and hardware redundancy.
ASIL C = ASIL B(C) + ASIL A(C)
ASIL D = ASIL B(D) + ASIL B(D), where you can combine two different 32-bit MCUs to achieve ASIL C or ASIL D safety levels
