Product overview


The automotive STM8 8-bit MCUs include the mainstream STM8AF Series and the ultra-low-power STM8AL Series. Based on STMicroelectronics Quality foundations, STM8AF and STM8AL Series product portfolios, and STM8AF and STM8AL Series embedded safety features, the STM8A-SafeASIL functional safety package helps users to market safety-critical STM8AF-based and STM8AL-based systems quickly, targeting the automotive safety integrity level standard ISO 26262 safety integrity level (ASIL A/B).

  • All features

    • STM8AF and STM8AL Series devices are AEC-Q100 qualified
    • MCU safety manual
      • Detailed list of safety requirements (assumptions of use) and examples to guide end users to use STM8 8-bit MCUs in systems implementing safety functions compliant to ISO 26262 and up to ASIL B
    • FMEA / FMEDA document
      • FMEA: detailed list of MCU failure modes and related mitigation measures to be adopted (qualitative analysis)
      • FMEDA: static snapshot reporting failure rates compliant to ISO 26262, computed at both MCU and basic function levels of detail
    • Specification document for self-test library
      • List of detailed safety requirements enabling STM8AF and STM8AL Series users to realize, in the framework of their ISO 26262-compliant software development process, the software self-test library required by the STM8AF and STM8AL Series safety manual to address CPU permanent failures
      • The quality and detail level of the specification enables its direct use in a development process compliant to ISO 26262-6 requirements
      • Includes the evidences and rationales behind the generation of the safety requirements for the completeness of end-user safety case
      • Application independent: can be used in potentially any end-user application
