Recently, AutoChips Inc., a wholly-owned subsidiary of NavInfo, announced to the public that it had added a new heavyweight member, AC 7801x, to its car-level MCU product line. This was the first 32-bit Cortex-M0+ car-level MCU chip of China after the first domestic car-level MCU chip, AC 7811, was put into mass production by AutoChips at the end of 2018, which further broke the technological monopoly of foreign MCU brands in the field of car body control and set a new benchmark for the domestic car semiconductor industry.
