Functional safety package to achieve IEC 61508 Safety Integrity Level (SIL2/3) certification with STM32

On the basis of the ST Quality foundations, the STM32 product portfolio and the STM32 embedded safety features, the STM32 SIL functional safety design package helps customers to quickly market STM32-based safety critical applications, targeting the industry safety standard IEC 61508 Safety Integrity Level (SIL2 / SIL3) in domains such as industrial, motor control, factory automation, power generation/conversion or medical.

Contact ST local representative to request the X-CUBE-STL software, FMEA and FMEDA documentation (NDA agreement required).

The X-CUBE-STL functional safety design package runs on STM32 microcontrollers, based on Arm® cores.

Note: Arm is a registered trademark of Arm Limited (or its subsidiaries) in the US and/or elsewhere.
