Infineon's AURIX & TRAVEO Microcontroller Families Extend Their Support for IEC 61508 Hardware and Software Metrics Enabling Industrial Safety up to SIL-3

­Industrial control systems must have a minimal error rate even in harsh environments, making safe and secure system development  crucial. The AURIX TC3x and TRAVEO T2G microcontroller product families from Infineon Technologies AG address these requirements with a wide range of integrated hardware functional safety and cybersecurity features. Both product families have extended their support for the IEC 61508 hardware and software metrics, including all documentation required for functional safety certification. In addition, Infineon’s AUTOSAR Microcontroller Abstraction Layer (MCAL) low level driver software product also supports the IEC 61508 metrics.

In addition to its successful deployment in the mobility market, Infineon’s AUTOSAR MCAL now enables numerous other functional safety applications including medical devices, industrial drives, programmable logic controllers (PLCs), robotics, indoor applications like elevators, or machinery. “With the AUTOSAR standard being used outside of automotive applications, we now support our customers by providing a suitable AUTOSAR MCAL software documentation that supports IEC 61508 metrics”, said Ralf Koedel, Vice President Microcontroller at Infineon. “The demand for minimal errors in harsh environments has tightened up the requirements for industrial control systems. With the AURIX and TRAVEO families 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 & safety manual).”

The Failure Modes Effects and FMEDA documentation provides a static snapshot showing 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 their industrial applications. In addition, Infineon has built 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.
