Infineon's embedded security controllers are ASIL-D certified according to ISO 26262:2018

     With the rise of electric vehicles, advanced driver assistance systems and connected driving, the demand for functionally safe electrical and electronic systems in vehicles is also growing. Infineon Technologies has reached an important milestone: its second-generation AURIX™ (TC3xx) microcontroller has become the world's first embedded safety controller certified to the highest Automotive Safety Integrity Level (ASIL D) according to the latest ISO 26262 standard. The standard proposes a globally binding certification process for the development and production of automotive safety-critical systems.

     Peter Schaefer, Vice President and General Manager of Automotive Microcontrollers at Infineon, said: "This certification strengthens our leading position in automotive safety. We decided on the security architecture of the second generation AURIX microcontroller before the new ISO 26262, but it still meets all the requirements of the ASIL D security controller. This is possible because we have adopted a holistic security model to create a complex and robust architecture. As a result, the second generation AURIX microcontroller provides the necessary safety and confidence to enable autonomous driving."

     The AURIX series has been very successful in safety-related applications. The leading autonomous driving computing platform uses AURIX as its safety master controller. In addition, this family of microcontrollers can be used to process sensor data in radar systems, as well as in many other applications such as engine and transmission control, braking, airbags and steering systems, central gateways, domain controllers, hybrid and electric vehicles.

     In addition to the automotive sector, the product family is increasingly being used in other safety-critical applications such as commercial vehicles and robotics. Therefore, Infineon's next step is to obtain IEC 61508 certification. IEC 61508 is a fundamental cross-industry functional safety standard and the basis for application-specific standards.

     The AURIX TC3xx device has up to six processor cores, each with a clock rate of 300 MHz. Up to four processors can have additional lock-step cores. With approximately 3,000 DMIPS, AURIX sets the bar for functional safe computing capabilities that support secure microcontrollers to achieve ASIL D certification. Other configurations include a secure internal communication bus and a distributed memory protection system. Furthermore, AURIX allows for the integration of software from different sources with different levels of security. This enables many operating systems and applications such as steering, braking, airbags and driver assistance systems to be hosted on the same platform.
