Suzhou CoreChip Completes Testing of Self-Developed Automotive HOD Chip CCM4202S-O, Meeting L2+ ADAS Safety Requirements

On June 18, Suzhou CCore Technology announced that its self-developed next-generation automotive touch-sensing MCU chip for hands-on detection (HOD) in steering wheels, the CCM4202S-O, has successfully completed all internal testing, meeting required specifications. Specifically designed for automotive HOD (Hands-On Detection) systems, the chip is fabricated using a 40nm EFLASH process and complies with automotive Grade 2 reliability standards as well as functional safety requirements up to ASIL-B. The CCM4202S-O integrates 32KB of SRAM, 512KB of FLASH, and 4KB of analog EEPROM. It features a 16-channel TSI capacitive touch-sensing module, along with automotive communication and signal acquisition peripherals including CAN FD, LIN, multiple SPI interfaces, and ADCs. The chip is available in both LQFP48 and LQFP64 package options, accommodating various steering wheel controller hardware designs of different sizes. HOD systems are mandatory safety components for Level 2 (L2) and higher advanced driver-assistance systems (ADAS), continuously monitoring whether the driver’s hands remain in contact with the steering wheel to prevent prolonged periods of unattended vehicle operation. According to China’s mandatory national standard for intelligent connected vehicles, all newly certified L2/L2+ vehicles must be equipped with HOD systems starting January 1, 2027, with a 13-month transition period provided for currently sold models. Industry forecasts predict that by 2026, HOD adoption in new vehicles in China will reach 65%. Previously, integrated touch-sensing MCUs used in this domain were primarily sourced from overseas suppliers. The launch of the CCM4202S-O is expected to alleviate supply constraints faced by domestic automakers and Tier 1 suppliers for steering wheel hands-off detection chips. Multiple downstream customers have already initiated hardware module development, supporting control software design, and preliminary testing based on this new chip.
