Recently, BYD Semiconductor said that it has launched the automotive grade 8-digit MCU BS9000AMXX series in March 2022, and the application areas are body domain sensor detection and control, body domain end effect mechanism, and the client application development project of the product has been launched.
BYD Semiconductor Co., Ltd. was established on October 15, 2004. The company is committed to the core technology of semiconductor research and development, manufacturing, sales, integration services. BYD Semiconductor has solved many core chip supply problems for BYD Automobile and stabilized the chip supply problems in the epidemic.
According to public information, BYD's semiconductor product camp includes industry-grade general-purpose MCU chips, industrial-grade three-in-one MCU chips, vehicle-grade touch MCU chips, vehicle-grade general-purpose MCU chips, and battery management MCU chips, etc., with cumulative shipments reaching 2 billion.
The automotive grade 8-bit MCU BS9000AMXX chip launched this time adopts S8051 core, the frequency is up to 24MHz, based on the standard 8051 instruction pipeline structure, including 31KB FLASH, 2KB SRAM, 1KB EEPROM, to meet the AEC-Q 100 GRADE 1 level.
According to BYD, the chip can be used in many application scenarios in automotive electronics, such as car interior lights, mood lights, door handles, air conditioning touch panels, various sensor applications, BLDC motor control, etc.
In terms of vehicle-grade MCUs, BYD launched the first generation of 8-bit vehicle-grade MCU chips in 2018 and the first generation of 32-bit vehicle-grade MCU chips in 2019. The 8-bit MCU BS9000AMXX series launched this time belongs to the new category of 8-bit vehicle-grade MCU chips.
summary:
BYD Semiconductor once said that if IGBT solves the bottleneck of automobile electrification, then the MCU is the key to solving the intelligentization of automobiles and plays a decisive role in the development of intelligent automobiles. At present, BYD has realized IGBT self-development and self-production, and the core technology of MCU may become its new direction.
