The high-performance motor drive chip incorporates ME core and RISC-V core. ME core integrates FOC module and CORDIC module that allow for automatic calculation of FOC or square-wave control by the hardware for sensored/sensorless BLDC/PMSM motors. RISC-V core is used for parameter configuration and routine processing. The dual cores work in parallel to achieve high-performance motor control. Interleaved two-phase boost PFC. The chip integrates high-speed operational amplifiers, comparators, high-speed ADC, CRC, SPI, I2C, UART, LIN, CANFD, DataMonitor, Timers, built-in LDO, which are suitable for FOC or square-wave based BLDC/PMSM motors.
