Infineon Technologies is to show a virtual prototype of a microcontroller based on the RISC-V open instruction set architecture for automotive applications next week.

This will sit in the Aurix family alongside devices based on the TriCore and ARM 32bit architectures and will evolve into a full digital twin of the RISC-V microcontroller family.

While Infineon says this is the first RISC-V automotive microcontroller in the market, it doesn’t give a timescale for silicon production (see software timeline below). There are also RISC-V microprocessor cores from Andes Technologies in Taiwan and Munich-based Codasip certified to the highest ASIL-D level for automotive applications already available as IP.

The timeline sees hardware variants with embedded AI developed in 2027, indicating production in 2028. Certifying the designs will take time, and the current Aurix TC4x TriCore microcontroller is only just entering production.

The RISC-V Aurix family will cover a wide range of automotive applications from entry-level MCUs up to high-performance MCUs, and Infineon beyond what is available in the market today.

This will be key for software defined vehicles says the company. “In software-defined vehicles, RISC-V is key to standardization and ecosystem compatibility, unleashing a new era of innovation and collaboration,” said Peter Schiefer, President of Infineon’s Automotive Division. “Infineon is committed to making RISC-V the open standard for the automotive industry.”
