On September 16, at the 6th Intelligent Automotive Chip Ecosystem Conference 2026, Liu Lin, Senior Marketing Manager for Automotive Business at Infineon Technologies and Head of RISC-V Ecosystem for Greater China, delivered a speech outlining Infineon’s strategic decision and roadmap to fully transition its next-generation automotive MCUs to the RISC-V architecture. In fiscal year 2025, Infineon’s automotive electronics business accounted for half of its total revenue, with Greater China contributing 38% of its global business. According to TechInsights data from April 2026, Infineon has been the world's largest automotive semiconductor supplier since 2019, and its MCU market share has increased from 32.1% in 2025 to 36%. Currently, Infineon employs a dual-architecture strategy for its MCUs: the mid-to-low-end TRAVEO™ T2G series, based on ARM cores, serves applications such as body control and HMI; while the mid-to-high-end AURIX™ series (TC2/TC3/TC4), built on Infineon’s proprietary TriCore™ core, targets domain controllers, powertrain systems, and battery management systems (BMS). In terms of ecosystem development, Infineon completed foundational toolchain deployment—including compilers, debuggers, and virtual prototypes—by 2024. From 2025 to 2026, it expanded into the operating system layer: collaborating with Vector, Neusoft Reach, and Puhua on AUTOSAR adaptation, and advancing community partnerships around open-source RTOS platforms including FreeRTOS, Zephyr, and NuttX. In March 2026, Infineon launched the DRIVECORE™ RISC-V Virtual Prototype Pre-integrated Evaluation Kit, which is already being used by select Chinese OEMs and Tier 1 suppliers for early-stage evaluation. Infineon also plans to introduce a cloud-based MCU evaluation platform tailored for SDV software development. On standardization, the China Automotive Chip Certification Consortium (CACC) established an Automotive RISC-V Working Group in 2025, with Infineon participating as a core member. The “Research Report on Standardization Requirements for Automotive RISC-V Chips,” published by the Automotive Standards Committee, was released in July 2026, with Infineon contributing to its drafting. Regarding localization, Infineon has engaged in requirement discussions with domestic OEMs and Tier 1 suppliers on its next-generation RISC-V products, covering use cases such as domain control, cross-domain integration, cockpit-driving fusion, and electrified powertrains. Additionally, Infineon maintains localized production lines and part numbers in China for MCUs, memory, MOSFETs, and other products.
