Many industries and applications are recognizing the importance of Functional Safety, not only to achieve specific safety goals but also as a way to reduce product-related costs and product lifetime expenses. Engineers around the globe are using products that are certified to internationally recognized standards for Functional Safety such as the IEC 61508.

Free software to create safety-certified new products 

STMicroelectronics is helping engineers design safer applications, more quickly and cost-effectively, with new software for its STM32 microcontrollers. The software is 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 recognized safety standard IEC 61508.

ST’s STM32 SIL Functional Safety Design Package contains full documentation to support the development of STM32-based embedded systems to meet IEC 61508 requirements for functional safety.

The SIL Functional-Safety Design Package comprises documentation and the X-CUBE-STL, a software Self-Test Library certified to IEC 61508 SIL3. The package is initially available for the STM32F0 series. ST plans to introduce equivalent packages for all other series in the STM32 family throughout 2018 and 2019.

“To help our customers deliver safety-certified new products to market quickly and efficiently, we are making this high added-value, the ST-designed comprehensive package including certified software available free of charge; an industry-first,” said Daniel Colonna, Microcontroller Division Marketing Director, STMicroelectronics. “Moreover, by providing this offer on our STM32 microcontroller portfolio, the SIL Functional-Safety Design Package will give extra flexibility to our customers and help optimize their bill of materials.”

In the announcement, the company noted that TÜV Rheinland has positively assessed X-CUBE-STL-F0 according to the functional safety standard IEC 61508:2010. TÜV Rheinland is a leading international certification institute for functional safety certification to relevant international standards.

Swiss-based sensor manufacturer Contrinex is the first to use ST’s Functional-Safety Design Package to certify safety products based on STM32F0 microcontrollers.

Commented Nicolas Jouanne, Embedded Software Development Project Leader at Contrinex, “The proven robustness of ST microcontrollers, combined with the SIL functional-safety design package, is a comfortable choice for our safety product development.”

Availability: 

The Functional-Safety Design Package for STM32F0 microcontrollers is available from www.st.com, free of charge, subject to Non-Disclosure Agreement (NDA) with ST. Equivalent packages for other STM32 series will be introduced throughout 2018 and 2019.
