Infineon Technologies has extended its AURIX TC3xx MCAL by adding support for AUTOSARv4.4.0 to the existing AUTOSARv4.2.2 MCAL. This makes software development easier 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 compatible software products. Support for IEC 61508 SIL-2 will be provided with version 2.30.0.
The latest version targets AUTOSAR applications in all automotive domains, including engine, chassis, safety and bodywork, but also commercial agricultural vehicles (CAV), industrial and 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 domain D, simplifying the system-level security argument.
For developers, this creates competitive advantages: they can work with a production-ready driver with ASIL-D compliant security qualification and certification, helping to avoid systematic failures. Additionally, the driver supports ISO 21434 for continuous monitoring. Infineon partners further assist developers with additional services and support.
Main features
The listed AUTOSARv4.4.0 MCAL software packages were shipped with drivers enabled:
- MC-ISAR Basic: MCU, DIO, ICU, GPT, PWM, SPI, ADC, WDG, OCU, FLS, RATE, CAN, CanTrcv, LIN, BFX, CRC
- MC-ISAR With Enhanced: FlexRay, Ethernet
