The MCU executes firmware to measure cell voltages and temperatures, perform analog-to-digital conversion, process data, and communicate with the BMC or other modules. It enables real-time monitoring for cell balancing, SOC estimation, and safety.
Typical supply voltage is 2.7–5.5 V DC, and clock frequency ranges from 16 to 80 MHz. These are reference ranges; actual values depend on the specific MCU model and application.
It uses standard communication interfaces such as CAN, SPI, I2C, or UART. The number of channels typically ranges from 2 to 4, depending on the model.
Verify all parameters (supply voltage, clock, memory, ADC resolution, temperature range, power, package, ESD rating, interfaces, GPIO, standby current) against the application requirements. Also confirm compliance with relevant standards, such as IEC 61000-4-2 for ESD, with the legal manufacturer or supplier.
