AURIX™ embedded software: Enhanced MC-ISAR TC3xx MCAL adds ASIL D and SIL-2 compliant drivers to support AUTOSARv4.4.0

by gabi

Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) extends its AURIX™ TC3xx MCAL by adding support for AUTOSARv4.4.0 to the existing AUTOSARv4.2.2 MCAL. This facilitates software development for OEMs. For ASIL D applications, the MC-ISAR TC3xx roadmap has been updated to also provide ASIL D compliant drivers. With the upcoming Maintenance Release 2.25.0, the driver will include ASIL D compliant software products. Support for IEC 61508 SIL-2 will be provided with Release 2.30.0. The latest release aims at AUTOSAR applications in all automotive domains, including engine, chassis, safety, and body, but also commercial agricultural vehicles (CAV), industrial as well as marine applications.

The biggest advantage of the MC-ISAR AS440 EXT TC3xx is its support for the latest standards, eliminating the need for additional drivers for ASIL D argumentation. It facilitates software partitioning and provides more flexibility by allowing the driver to run in an ASIL D domain, simplifying system-level security argumentation. For developers, this creates competitive advantages: They can work with a production-ready driver with a qualification and safety certification that is ASIL D compliant, helping to avoid systematic failures. In addition, the driver offers ISO 21434 support for continuous monitoring. Infineon’s partners further assist developers with additional services and support.

Key features

The listed AUTOSARv4.4.0 MCAL software packages have been provided with the enabled drivers:

  • MC-ISAR Com Enhanced: FlexRay, Ethernet
  • MC-ISAR MCD MCAL Complex Driver: offers eleven complex drivers in addition to the standard AUTOSAR drivers: DMA, FLSloader, UART, DS-ADC, SMU Safety Management Unit, DEMOCD: HSSL, SENT, I²C, IOM I/O Monitoring, STM System Timer, IRQ Interrupt Request.

In addition, the software packages include important features like AUTOSAR BFX and CRC library, ASPICE L2, ASIL D process for FFI, MISRA 2012 change 1 (CERT-C) compliance (AUTOSARv4.4.0), and ISO 21434 support for continuous monitoring.


Key ASIL D compliant drivers with IEC 61508 SIL-2 support will be available from mid-2023. More information is available at
