IEC60730B Library User's Guide for Arm Cortex-M33 Microcontrollers
User guide for the NXP IEC60730B safety library supporting Arm Cortex-M33 MCUs, including LPC55Sxx and MIMXRT118x, for compliance with IEC 60730 and UL 60730 standards.
Overview
This document is a user guide for the NXP IEC60730B core self-test library designed for microcontrollers based on the Arm Cortex-M33 core. The library provides independent functions for performing safety self-tests compliant with international standards including IEC 60730, IEC 60335, UL 60730, and UL 1998. It covers core-dependent tests such as CPU registers, program counter, stack, and variable/invariable memory, alongside peripheral-dependent tests for clocks, digital and analog I/O, watchdogs, and touch-sensing interfaces. The guide details implementation for LPC55Sxx, LPC55xx, and MIMXRT118x device families across IAR, Keil, and MCUXpresso IDEs.
Use Cases
- Functional safety compliance for household appliances
- Industrial control system safety certification
- Embedded software diagnostic self-testing
- Implementation of Class B safety routines on LPC55Sxx and MIMXRT118x MCUs
