This program is mainly used in the body controller.
The body control module (BCM for short) can also be called a body computer; generally, the common functions of the body controller include controlling power windows, electric rearview mirrors, air conditioners, headlights, turn signals, anti-theft locking systems, central control locks, defrosting devices, etc. In addition, the body controller can be connected to other on-board ECUs through the bus, and can communicate with external computers through CAN/LIN and various small nodes; in some high-end cars, some BCM also integrates air-conditioning damper control, tire pressure monitoring, PEPS, gateway and other functions.
In the selection of BCM master control, this article selects SemiDrive's E3210 (the chip has passed the certification of ASIL-B and AEC-Q100) and produces an evaluation board scheme based on the chip, which integrates CAN, LIN, UHF interface, low frequency interface, ADC,DAC, DIN, norflash, hyperflash, SD card, Ethernet interface, USB, USB to serial port, buzzer, speaker, JTAG programming interface, button, dial code switch and other modules. Other communication interfaces such as SPI, UART, I2C, I2S, GPIO, etc. are also introduced from the main MCU in the form of pin rows to meet the functional testing and development of different needs. This solution maximizes the display of the peripheral parts of the E3210 to the greatest extent, which can make it easy for engineers who are first exposed to SemiDrive E3 series MCUs to quickly become familiar with the use of the IC.
