Application scenarios:

AC7840x automotive MCU has been put into mass production, and its application projects include: BCM body control module, lighting control, automotive instrument, automotive air conditioning control, electronic shifter, new energy battery management BMS, etc.

Future prospects:

As the automotive electronic architecture gradually evolves from distributed to domain controllers, the value of a single vehicle's MCU will continue to increase, and the MCU product form will develop in two directions: domain control master nodes and intelligent edge nodes. Aiming at the multi-core, high computing power, large capacity, and rich network communication interfaces of the domain controller MCU, Jiefa Technology has planned the AC787x series of multi-core MCUs to meet the ASIL-D functional safety requirements, which can be applied to body domains, power domains, chassis domain controllers, as well as general-purpose gateways and regional controllers; in the field of intelligent edge node applications, Jiefa Technology will continue to enrich the existing product matrix, and based on AC781x, AC7801x, AC7802x, and AC7840x, launch more small-sized, low-power, automotive-grade MCU products that can meet the needs of intelligent sensors and actuators.
