STMicroelectronics Safety-Documentation Package for STM8A Automotive MCUs Aids ISO 26262 Certification

August 4, 2015  by  

STMicro N3713S -- Aug 3 2015 -- STM8A Safety Documentation_IMAGESTMicroelectronics has published a safety manual and FMEDA (Failure Modes, Effects, and Diagnostic Analysis) document that helps to streamline ISO 26262 functional-safety certification up to ASIL-B for systems containing the company’s STM8AF automotive microcontrollers.

With features including CAN and LIN drivers, and touch-sense/LCD-control capability, ST’s AEC-Q100- qualified STM8AF series is a popular and economical choice for body and infotainment applications such as seat adjusters, instrumentation, and lighting controllers.

Recognizing that reliable operation enhances comfort and driver concentration for a better, safer user experience, Tier 1 equipment suppliers now tend to design these systems to meet ISO 26262 functional-safety standards at ASIL A or B. ST’s new STM8A-SafeASIL safety tools show designers how best to work with the microcontroller to achieve the desired safety integrity level, thereby helping ensure successful certification.

The safety manual has been developed with assistance from YOGITECH, a leader in providing functional safety solutions. It provides guidance for hardware design and software integration, including a list of tips, to help engineers ensure correct and safe operation of the STM8AF and so eliminate system failures due to the microcontroller.

The accompanying FMEDA describes the failure probabilities of STM8 IP blocks to help designers ensure their applications achieve the desired system safety integrity.

According to STMicroelectronics, this safety documentation package is the first in the industry for 8-bit microcontrollers. The safety manual is available immediately to STM8A customers, free of charge, at, while the FMEDA, also free of charge, is available conditional upon signing a Non-Disclosure Agreement (NDA).
