Dongfeng Motor today officially announced that the DF30, China’s first domestically developed high-performance automotive-grade MCU chip, is steadily moving toward mass production and vehicle integration, with its first application in an engine ECU. It has already been successfully validated on multiple vehicle models, including Dongfeng eπ007 and Mengshi M817. This also means that vehicles under the Dongfeng brand will soon be equipped with 100% domestically controlled and self-developed chips, breaking the long-standing monopoly of foreign manufacturers in this field. DF30 chip It should be noted that an MCU (Microcontroller Unit) chip can be understood as the core brain of a vehicle’s electronic control unit (ECU). It is responsible for receiving multiple sensor signals, performing real-time calculations, and outputting control commands to drive the engine. Its computing speed and stability directly determine the safe operation of the entire vehicle. Currently, such high-performance automotive-grade MCU chips have long been monopolized by foreign manufacturers such as Renesas and Infineon. If the supply chain is disrupted, domestic automobiles could fall into a predicament of being “chip-less.” DF30 chip According to Dongfeng Motor, the DF30 chip is built on a self-developed RISC-V multi-core architecture and uses a domestic 40nm automotive-grade process, achieving a closed-loop of full domestic localization from design, manufacturing, to packaging and testing. In terms of safety, the chip currently meets the highest functional safety level in the automotive industry, ASIL-D, and has passed 295 tests covering basic performance, extreme stress, and application tests, including verification in extreme cold (-43°C), high temperature (155°C), and vibration environments. The company emphasizes that the chip will be compatible with the domestically developed AutoSAR automotive software operating system, and can be widely used in areas such as powertrain control, chassis, electronic information, and driving assistance, covering core scenarios including engine and chassis control for fuel vehicles, as well as the three-electric system (battery, motor, and electronic control) for new energy vehicles. DF30 chip undergoes extreme performance testing. On the R&D ecosystem front, as early as 2022, Dongfeng Motor partnered with eight enterprises and institutions including China Information and Communication Technologies Group’s Binary Semiconductor Co., Ltd., Wuhan LinDian, and Wuhan University of Technology to establish the “Hubei Provincial Automotive-Grade Industry Technology Innovation Consortium.” Since its release in November 2024, the DF30 chip has yielded over 50 invention patents and integrated circuit layout designs. Additionally, Dongfeng has taken the lead in formulating eight related standards. Next, Dongfeng Motor will develop other variants of the DF30 for different application scenarios to achieve product serialization, while also initiating R&D on domain controller chips.
