In recent years, drastic technological innovation in the industrial equipment market and automotive sectors following the emergence of automated driving and ADAS has brought about the need for standards such as ISO 26262 and IEC 61508 that define functional safety and contribute to the prevention of accidents in the event of an emergency for constructing safer systems. For example, in the automotive field a growing number of companies are promoting functional safety not only among vehicle manufacturers (OEMs), but Tier 1 electronics equipment suppliers as well, making it an increasingly important requirement worldwide. What’s more, in the 2nd Edition of the ISO 26262 standard on automotive functional safety released in December 2018, a new chapter was added containing guidelines on the application of semiconductors for functional safety.
ROHM’s Approach to Functional Safety
ROHM started the process of acquiring certification for ISO 26262, a functional safety standard for automotive electrical and electronic systems, in 2015, then acquired ISO 26262 development process certification from 3rd party certification body TÜV Rheinland in March 2018. As a result, ROHM’s development process is recognized as being compliant with ISO 26262 standard. At the same time, we have gradually expanded our portfolio to include documents required for functional safety in vehicles, and currently feature a lineup of more than 1,000 compatible part numbers.
Going forward, ROHM will continue to expand its lineup of functional safety products not only for the automotive sector, but for the industrial equipment field as well.
Functional Safety Product Categories and Documents
ROHM has identified three functional safety product categories. (Currently, only the automotive field is supported.)
- FS process compliant
- A product that has been developed based on an ISO 26262 design process compliant to the ASIL level described in the datasheet.
- FS mechanism implemented
- A product that has implemented safety mechanism to meet ASIL level requirements described in the datasheet.
- FS supportive
- A product that has been developed for automotive use and is capable of supporting safety analysis with regard to the functional safety.
