Functional safety microcontrollers: ISO 26262:2018 - The benchmark in functional safety

ISO 26262 defines the development of electric and electronic automotive systems with regard to their functional safety integrity levels. The aim of this standard is to reduce possible hazards caused by the failure and malfunction of such systems. The safety requirements for the development process depend on the ASIL rating of the target application and can range from ASIL A to ASIL D. Applications such as steering or braking systems are rated with the highest ASIL D level.

A failure in such a system can lead to an out-of-control vehicle, possibly resulting in fatal injuries. All newly developed parts, which address a certain safety goal will be based on an ISO 26262-compliant development flow, thereby allowing direct use in all safety-relevant applications. Devices which are developed prior to the ISO 26262 as a QM part can nevertheless be used in ISO-compliant systems as those outlined in part 8 clause 13 of the standard. In such cases, it is mandatory “to provide evidence of the suitability of hardware components and parts” for use in ISO-compliant systems and also to provide failure modes, their distribution and diagnostic capability.

To support our customers as they strive to achieve the highest ASIL at the system level, Infineon provides both the necessary support for qualification of existing pre-ISO 26262 safety and security microcontrollers, and the fully ISO 26262-compliant MCUs of the future.
