MISRA C

Definition

A set of coding guidelines for the C language developed by the Motor Industry Software Reliability Association. Defines required and advisory rules to prevent undefined behavior, improve code safety, and ensure portability in safety-critical embedded systems.

Why it matters

Required for automotive (ISO 26262), medical (IEC 62304), and industrial (IEC 61508) firmware. Static analysis tools check compliance, but AI code review can catch semantic violations that pattern-matching tools miss.

Relevant MCU families

STM32 NXP i.MX RT Renesas RA MSP430
