Design support site ensuring functional safety

In recent years, following the acceleration of technical innovation represented by ADAS (Advanced Driver Assistance System) in the automotive sector, it has become necessary to consider functional safety to help prevent accidents. At the same time, in response to the increasing importance to ensure vehicle safety by supporting safety requirements at the device level for onboard electrical systems, a 2nd edition of ISO 26262, the international standard for functional safety, was released in December 2018 that adds a chapter on semiconductor.

ROHM quickly responded to these needs, and in March 2018 successfully acquired ISO 26262 development process certification from 3rd party certification body TÜV Rheinland. Since then, ROHM gradually expanded its portfolio to include documents required for functional safety design, and currently features a lineup of more than 1,000 compatible part numbers.

This new special site consolidates functional safety compliant products under the brand name ComfySIL that will be used on the web and relevant documents to significantly improve product searchability. The ComfySIL brand targets not only vehicles, but also functional safety for other markets as well, and going forward we will expand our lineup products that support functional safety for the industrial equipment field as well.

As the role of semiconductors in the automotive and industrial equipment markets continues to grow, ROHM will strive to manufacture high quality products and contribute to the creation of a safer, more secure, environmentally friendly automotive society through its products.

ROHM automotive product initiatives

Under a corporate objective of ‘Quality First’ established since its founding, ROHM utilises a vertically integrated production system within the group that infuses superior quality into every process, from development to manufacturing, while also providing reliable traceability and an optimised supply chain.

We have built a dedicated line for automotive products and carry out development that complies with quality management system (IATF 16949) and electronic product reliability (AEC-Q100/101/102) standards.

In 2015, ROHM began to establish an ISO 26262 process to address functional safety, and in March 2018 acquired ISO 26262 development process certification from 3rd party certification body TÜV Rheinland.

Functional safety categories and documentation

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.
