Technical requirements and application prospects of power domain control chips

The power domain control chip is an intelligent powertrain management unit, mainly used for powertrain optimization and control. The requirements for the power domain control MCU include high main frequency (600MHz~800MHz), high functional safety level (ASIL-D level), large capacity memory (4MB RAM), etc. In addition, it is also necessary to support communication interfaces such as multi-channel CAN-FD and 2G Ethernet, and meet the automotive reliability standard AEC-Q100 Grade 1. At present, the E3 series products launched by the domestic chip manufacturer Xinchi Technology have been able to meet these requirements and have been widely used in the market.
