STMicroelectronics STM32 SIL Functional-Safety Design Package

Click2Contact

STMicroelectronics is helping technology brands design safe applications with its software for STM32 microcontrollers. Created for designers of STM32-based devices in the field of industrial controls, robots, sensors, medical or transportation, which must be certified up to safety integrity level (SIL) 2 or 3 of the recognised safety standard IEC 61508, the STM32 SIL Functional-Safety Design Package is said to simplify system development and certification.

The package comprises documentation and the X-CUBE-STL, a software Self-Test Library certified to IEC 61508 SIL3. It is initially available for the STM32F0 series; ST will continue to introduce equivalent packages for all other series in the STM32 family throughout 2018 and 2019. There are currently more than 800 STM32 microcontroller variants that give product developers the flexibility to optimise price, performance and feature integration.

TÜV Rheinland, an international certification institute for functional safety certification to relevant international standards, has positively assessed X-CUBE-STL-F0 according to the functional safety standard IEC 61508:2010. Sensor manufacturer Contrinex has meanwhile become the first to use the design package to certify safety products based on STM32F0 microcontrollers.

The design package for STM32F0 microcontrollers is available free of charge, subject to a non-disclosure agreement (NDA) with ST. Equivalent packages for other STM32 series will be introduced throughout 2018 and 2019.
