Infineon Technologies AG and Subaru Corporation are collaborating to enhance driver safety, confidence and comfort in future Subaru vehicles. Infineon plays a key role in Subaru’s integrated electronic control unit (ECU) for next‑generation advanced driver assistance systems (ADAS) and vehicle motion control: Infineon’s latest AURIX microcontroller (MCU) enhances the real-time capability of this ECU compared to previous generations, supporting faster, more reliable processing of vehicle and sensor information.
“As advanced driver assistance systems become more sophisticated, reliable real-time operation across the entire system is key,” said Peter Schaefer, Executive Vice President and Chief Sales Officer, Automotive at Infineon. “With our market-leading microcontroller family AURIX, we support Subaru in building the foundation needed to deliver dependable decision-making and control across the vehicle.”
“Subaru is working on the development of an integrated electronic control unit that coordinates next‑generation EyeSight and vehicle motion control for future Subaru vehicles,” said Eiji Shibata, Executive Officer and Chief Digital Car Officer, Subaru Corporation. “Infineon’s AURIX MCU is a core technology that will support robust sensor data fusion and real‑time control within this integrated ECU, and is a key element enabling the evolution of next‑generation ADAS and vehicle motion control. We have built a strong relationship of trust with Infineon over many years and have collaborated from the early stages of development to optimise the design of the AURIX MCU. We value this trusted partnership and look forward to Infineon’s next‑generation MCU.”
In the integrated ECU, Subaru leverages Infineon’s most advanced automotive MCU – AURIX TC4x – to strengthen computing and in-vehicle networking. AURIX TC4x will serve as the main controller for next-generation ADAS functionality controlled by the ECU. In real-time, it enables sensor data fusion as well as decision-making and control, by utilising inputs from camera, radar and other sensors – delivering faster and more reliable driver assistance functions. TC4x combines up to six cores at 500 MHz in lockstep operation and automotive functional safety up to ASIL-D.
Infineon and Subaru have already collaborated for Subaru’s current generation ADAS. Both companies will deepen their collaboration around in-vehicle computing and networking in the future and will drive technology development and value creation toward safer and more secure mobility.
One year ago, Infineon climbed to the number one position in the global microcontroller market, after having reached this position for automotive microcontrollers specifically already in 2023. Since then, the company has further strengthened its position by developing technology ready to meet car manufacturers’ future MCU requirements, such as paving the way for RISC-V to become the open standard for automotive MCUs. Furthermore, Infineon has strengthened its MCU-adjacent product portfolio through the acquisition of the automotive Ethernet business from Marvell in August 2025. With this move, Infineon has created the most comprehensive system offering in the industry for centralised computing architectures in software-defined vehicles.
