Functional safety package to achieve IEC 60730 Class B certification with the STM8

The worldwide harmonized IEC 60730-1 and IEC 60335-1 safety standards define the test and diagnostic methods to ensure the safe operation of embedded hardware and software for household appliances controlled by electronic programmable devices.

The STMicroelectronics STM8-SafeCLASSB functional safety package is dedicated to all products based on the robust STM8 proprietary core. It provides a comprehensive tool that significantly reduces the effort, time and costs needed to achieve Class B safety level certification, which is recognized by the above-mentioned standards for applications intended for the European, American and Asian markets.

The STM8-SafeCLASSB functional safety package consists of a set of certified STM8 core self-testing procedures, including examples of their integration in an application, and associated documentation.

For further details refer to the application note AN3181 “Guidelines for obtaining UL/CSA/IEC 60730-1/60335-1 Class B certification in any STM8 application”, available on
