The high-performance motor drive chip incorporates MotionEngine ME core and 8051 core with 32K FLASH and 1k75 RAM.
ME core integrates FOC, MDU, LPF, PID and SVPWM modules that allow for automatic calculation of FOC or square-wave control by the hardware for sensored/sensorless BLDC/PMSM motors. 8051 core is used for parameter configuration and routine processing. Most of 8051 core instruction cycle takes 1T or 2T clock cycle(s).
The dual cores work in parallel to achieve high-performance motor control. The chip integrates high-speed operational amplifiers, comparators, high-speed ADC, multiplier/divider, CRC, Serial Interfaces, Timers, PWM module and high-voltage LDO, which are suitable for FOC or square-wave based BLDC/PMSM motors.
