ABOV AC33M6128 is special purpose microcontroller for motor application. This microcontroller brings high-performance 32-bit computing to low cost system solution. AC33M6128 provides 3-phase PWM generator units which are suitable to inverter motor drive system. Built-in 3-phase PWM generator controls one inverter motor. Three 12-bit high speed ADC units with 16-channel analog multiplexed inputs support to get feedback information from motor. It can control up to two inverter motor or one inverter motor and PFC(Power Factor Correction) function simultaneously. Powerful and various external serial interface help to communicate with on-board sensors and devices.
