Infineon makes it easier for OEMs to develop safety-relevant software: the Microcontroller Abstraction Layer (MCAL) for the Aurix TC3xx now also supports Autosar v4.4.0. In addition, the company has updated the MC-ISAR TC3xx roadmap – so that ASIL D-compliant drivers can also be provided in the future.
The next Maintenance Release 2.25.0 for the Aurix processors will include drivers for ASIL D-compliant software products. Support for the FuSa standard IEC 61508 SIL-2 will also be provided with Release 2.30.0. The latest release targets autosar applications in all automotive areas, including engine, chassis, safety and body, but also in agricultural commercial vehicles (CAV), industrial and marine applications.
The biggest advantage of the MC-ISAR AS440 EXT TC3xx is that it supports the latest standards, eliminating the need for additional drivers for ASIL D argumentation. It facilitates software partitioning and provides more flexibility as the driver can 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 whose qualification and safety certification is ASIL D-compliant. Systematic errors can thus be avoided. In addition, the driver offers ISO 21434 support for continuous monitoring. Infineon’s partners also support developers with additional services and support.
The Autosar v4.4.0 MCAL software packages listed have been provided with the released drivers:
- MC-ISAR Basic: MCU, DIO, ICU, GPT, PWM, SPI, ADC, WDG, OCU, FLS, FEE, CAN, CanTrcv, LIN, BFX, CRC.
- MC-ISAR Com Enhanced: FlexRay, Ethernet
- MC-ISAR MCD MCAL Complex Driver: offers eleven complex drivers in addition to the Autosar standard 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 key features such as Autosar BFX as well as 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.
