Aurix and Traveo MCUs support IEC 61508 for SIL-3 safety
Industrial control systems must have a minimal error rate even in harsh environments. Infineon has announced that its Aurix TC3x and Traveo T2G microcontroller families address these requirements with a wide range of integrated hardware functional safety and cybersecurity features. Infineon has extended support from ISO26262 to IEC61508 hardware and software metrics, including all documentation required for functional safety certification, for both microcontroller families. In addition, Infineon’s AutoSAR Microcontroller Abstraction Layer (MCAL) low level driver software product supports the IEC 61508 metrics.
The driver software has been deployed in the mobility market and now enables other functional safety applications including medical devices, industrial drives, programmable logic controllers (PLCs), robotics together with indoor applications such as lifts/elevators or machinery.
Ralf Koedel, vice president, microcontrollers, at Infineon, commented: “The demand for minimal errors in harsh environments has tightened up the requirements for industrial control systems. With the . . . extended support for IEC 61508 metrics, however, developers can count on a series of proven microcontrollers to design safety-critical applications and rely on the available diagnostic analysis documentation (FMEDA and safety manual).”
The failure modes effects and FMEDA documentation shows IEC 61508 failure rates and safety metrics calculated at both MCU and basic function levels. By extending the support of the Aurix TC3x and Traveo T2G microcontrollers from ISO26262 to IEC61508 metrics, developers can achieve SIL-1-3 for industrial applications.
Infineon added that it has created a strong ecosystem of design partners to pave the way for safety-critical designs up to SIL-4 and offers reliable support for functional-safety certification.
The Aurix TC3x and Traveo T2G microcontrollers will be exhibited at Embedded World 2023 (14 to 16 March 2023) in Nuremberg, Germany at the Infineon stand Hall 4A – 138.
