Industrial Functional Safety for 32-bit MCUs

IEC 61508 is an international standard for the functional safety of Electrical, Electronic and Programmable Electronic (E/E/PE) systems. It defines functional safety as a part of the overall safety relating to an Equipment Under Control (EUC) or a system. The EUC can be as simple as a switch or as complex as a Programmable Logic Controller (PLC). IEC 61508 encompasses four different Safety Integrity Levels (SILs), with SIL 1 being the lowest level and SIL 4 the highest level of safety in E/E/PE systems.

We offer the following resources to help you meet your functional safety requirements:

• MCUs designed and developed in compliance with a certified IEC 61508 functional safety management process
• IEC 61508 Failure Modes, Effects, and Diagnostic Analysis (FMEDA) reports
• IEC 61508 safety manual
• Diagnostic software libraries
• Development ecosystem for functional safety applications with TÜV SÜD-certified MPLAB^® XC C compilers and a qualification package for the MPLAB ecosystem

For many functional safety applications, redundancy or a dual-channel solution can be created for implementing a higher safety level for SIL 3. For example, two MCUs using the SIL 2 STL can be used to achieve SIL 3 in an overall system.

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.
