Software eases standard compliance for MCU-based appliances

STMicroelectronics has announced the availability of a free software that ensures standards compliance for household appliances that use its STM32 flash MCU. The software library is designed to simplify testing, securing end-product approval and compliance with the demands of the IEC 60335-1 standard.

Since October 2007, IEC 60335-1 has required the software of MCU-based appliances to be evaluated according to its impact on overall consumer and application safety. When some of the fault detection relies on the microcontroller, the embedded code must contain self-test routines, and must be evaluated under the so-called Class B requirements for its ability to detect safety critical failures.
