Dongfeng Motor Corporation, headquartered in the Wuhan Economic & Technological Development Zone (WEDZ), has achieved a milestone in China's automotive industry with the development of the DF30, the country's first high-performance automotive-grade MCU chip.
The DF30 chip acts as the "brain" of the engine control unit (ECU), a critical component for vehicle safety and functionality. It processes real-time signals from various engine sensors and issues control commands to drive the engine.
To ensure the DF30's performance under extreme conditions, Dongfeng's engineers conducted rigorous winter calibration tests at the Mohe cold region testing base, where temperatures were as low as -43 C.
Built on an open-source RISC-V multi-core architecture and manufactured using a domestic 40nm automotive-specific process, the DF30 meets the highest ASIL-D safety standards in the automotive industry.
Having completed 295 rigorous tests across basic performance, extreme stress, and real-world applications, the DF30 is compatible with domestic operating systems and supports a variety of core scenarios for both fuel and new energy vehicles.
Dongfeng Motor has achieved over 50 invention patents and integrated circuit layouts since launching the chip in 2024, establishing eight industry and team standards. It is now developing a full-chain innovation model covering demand, R&D design, and vehicle application.
