To assist automotive design engineers on the information related to ISO 26262 functional-safety certification, leading automotive semiconductor manufacturer STMicroelectronics has published a safety manual and FMEDA1 document that help streamline ISO 26262 functional-safety certification up to ASIL-B for systems containing its STM8AF automotive microcontrollers.
AEC-Q100 qualified STM8AF series MCUs with connectivity features such as CAN and LIN drivers, and touch-sense/LCD-control capability are widely used for body and infotainment applications such as seat adjusters, instrumentation, and lighting controllers. ST said its 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 prepared with assistance from YOGITECH 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.
This industry's first such safety manual doc is offered for free at http://www.st.com/stm8safety, The FMEDA is also free of charge but is available conditional upon signing a Non-Disclosure Agreement (NDA).
