Product overview

Description

On the basis of the ST Quality foundations, the STM32 microcontrollers portfolio and the STM32 embedded safety features, the STM32 SIL functional safety design package helps users to market STM32-based safety critical applications quickly, targeting the industry safety standard IEC 61508 safety integrity level (SIL2/SIL3) in domains such as industrial, motor control, factory automation, or power generation/conversion.
The package helps end-users to target safety applications according to various safety standards such as ISO 13849, IEC 62061 and IEC 61800.
  • All features

    • MCU safety manual
      • Detailed list of safety requirements (conditions of use) and examples to guide STM32 users to achieve safety integrity level certification in compliance with IEC 61508
      • SIL2 safety functions can be implemented with a single STM32 MCU; SIL3 safety functions implementation requires two STM32 MCUs in 1oo2 scheme
      • Available for the STM32F0, STM32F1, STM32F3, STM32F4, STM32F7, STM32G0, STM32G4, STM32H7, STM32L0, STM32L4, and STM32L4+ Series
    • MCU FMEA
      • Detailed list of MCU failure modes and related mitigation measures adopted (qualitative analysis)
      • Available for the STM32F0, STM32F1, STM32F3, STM32F4, STM32F7, STM32G0, STM32G4, STM32H7, STM32L0, STM32L4, and STM32L4+ Series
    • MCU FMEDA snapshot
      • Static snapshot reporting failure rates compliant to IEC 61508, computed at both MCU and basic function levels of detail
      • Available for the STM32F0, STM32F1, STM32F3, STM32F4, STM32F7, STM32G0, STM32G4, STM32H7, STM32L0, STM32L4, and STM32L4+ Series
    • X-CUBE-STL library
      • Software-based diagnostic suite designed to detect random hardware failures in STM32 safety-critical core components (CPU + SRAM + Flash memory)
      • Compliant to IEC61508 SC3 (SIL3) development process
      • Diagnostic coverage verified by state-of-the-art ST proprietary fault injection methodology
      • Application independent: can be used in potentially any end-user application
      • Compiler independent: delivered as object code
      • Certified by TÜV Rheinland
      • Includes the X-CUBE-STL user guide, a functional-only document related to STL functions (such as API details and performance figures)
      • Includes the X-CUBE-STL safety manual, the instructions/conditions of use for end user related to the use of X-CUBE-STL in a safety application
      • Available for the STM32F0, STM32F1, STM32F3, STM32F4, STM32F7, STM32G0, STM32G4, STM32H7, STM32L0, STM32L4, and STM32L4+ Series
