Subaru and Infineon Technologies partner on automotive microcontroller design for next-generation EyeSight system
Monday, March 9, 2026 at 10:42 AM
Subaru and Infineon have announced a partnership to collaborate on the design of automotive microcontrollers. Subaru will participate in the early design stages of Infineon's AURIX TC4x microcontrollers, which will be integrated into Subaru's next-generation EyeSight system and electronic control units for vehicle motion and AWD control.
Context
Automotive manufacturer Subaru has announced a strategic collaboration with Infineon Technologies to develop a next-generation integrated electronic control unit (ECU). The partnership focuses on the AURIX TC4x microcontroller, which will serve as the primary processing engine for Subaru’s future EyeSight driver-assist system. By integrating ADAS functionality with vehicle motion and AWD control into a single unit, the companies aim to achieve faster sensor data fusion and more reliable real-time decision-making.
The AURIX TC4x family represents a significant performance leap, featuring up to six cores running at 500 MHz and providing up to 15x the performance of previous generations. This hardware upgrade is essential for supporting advanced AI inference and high-resolution video processing required for Subaru’s goal of zero fatal road accidents by 2030. The system will also leverage virtualization technology to run multiple safety-critical applications concurrently while maintaining ASIL-D functional safety compliance.
This collaboration underscores a broader shift toward centralized E/E architectures in the automotive supply chain. While Infineon provides the real-time control layer via the AURIX platform, Subaru is also working with AMD for high-performance AI perception logic. By involving Infineon from the early design stages, Subaru is optimizing its hardware-software integration to reduce development lead times and part counts in its next generation of vehicles.
