Key technical requirements and development status of chassis domain control chips

Chassis domain control chips play an important role in the development of automobile intelligence. They involve multiple key parts such as the automobile's transmission system, driving system, steering system and braking system. The requirements for chassis domain MCUs mainly include high main frequency, high computing power, and high functional safety level. For example, the main frequency is not less than 200MHz, the computing power is not less than 300DMIPS, and the functional safety level reaches ASIL-D level. At present, international semiconductor manufacturers such as Infineon, NXP, Renesas, Microchip, TI and ST account for more than 99% of the chassis domain MCU market, and domestic manufacturers still have a lot of room for development in this field.
