Infineon's AURIX & TRAVEO: Secure Microcontrollers for Electronics

【Munich, Germany, June 12, 2023】 Industrial control systems must maintain the lowest possible error rates even in harsh environments, making the development of secure and reliable systems crucial. Infineon Technologies AG has introduced the AURIX™ TC3x and TRAVEO™ T2G microcontroller product lines, which meet these requirements through extensive integration of hardware functional safety and cybersecurity features. Both product lines expand support for IEC 61508 software and hardware technical specifications, including all the necessary documents for functional safety certification. Additionally, Infineon's AUTOSAR microcontroller MCAL low-level driver software products also support IEC 61508.

In addition to achieving success in the mobility market, Infineon's AUTOSAR MCAL is now being used to implement various other functional safety applications, including medical devices, industrial drives, programmable logic controllers (PLCs), robots, elevators, and indoor machinery. Ralf Koedel, Vice President of Infineon's Microcontroller Product Line, stated, "As the AUTOSAR standard is being used in non-automotive applications, we can now provide customers with AUTOSAR MCAL software files that support the IEC 61508 standard. The requirements for these systems have become more stringent as industrial control systems must maintain the lowest error rates in harsh environments. However, with the support of the AURIX and TRAVEO series expanding to the IEC 61508 standard, developers can use a range of mature microcontrollers to design safety-critical applications and refer to existing diagnostic analysis files (FMEDA and safety manuals)."

Fault mode effect and diagnostic analysis (FMEDA) files can create a static snapshot that displays IEC 61508 failure rates and safety metrics calculated at the MCU and basic function level. By expanding the support of AURIX TC3x and TRAVEO T2G microcontrollers from ISO 26262 to IEC 61508, developers can elevate the safety level of industrial applications to SIL-1-3. Furthermore, semiconductor technology company Infineon has established a robust design partner ecosystem, clearing obstacles for safety-critical designs up to SIL-4 and providing reliable support in terms of functional safety certification.
