PIC32MK microcontrollers (MCUs) combine 32-bit, 120 MHz performance with up to 1 MB of dual-panel live update Flash memory with Error Code Correction (ECC) for creating high-performance applications. They offer a range of communications and other peripherals combined with a rich feature set of high-performance analog motor control functions that make them an excellent option for developing motor control, industrial control, Industrial Internet of Things (IIoT) and automotive applications.
PIC32MK GPD/GPE/MCF Family (Legacy Products): These devices have CAN instead of CAN FD, lower-bandwidth op amps, no ECC on the Flash and no I2C interface.

Sensorless Single-Motor Drive with PIC32MK MCUs
PIC32MK MCUs make it easy and cost effective to implement single-motor drive applications. Their internal op amps reduce the need for external devices. Use their multiple Analog-to-Digital (ADC) conversion cores to dedicate an ADC to each motor phase that you want to measure rather than sharing the conversion of two or more phases on a single ADC. This reduces code complexity and increases resolution since you can capture more samples per phase without having to calculate complex timing between phases on a single ADC. Internal high-speed comparators with PWM fault triggering can also be used as over-current protection across the two measured phases.
Sensorless Dual-Motor Drive with PIC32MK MCUs
Many motor control applications require multiple motors. With their hefty selection of integrated peripherals, the PIC32MK series of MCUs is up to the challenge of driving dual, sensorless motor applications. Although it is similar to the block diagram for single-motor, dual-shunt sensorless control, this block diagram shows that the peripheral requirements are doubled for two motors. Since the PIC32MK MCUs offer seven ADC conversion cores, you don’t have to worry about sharing converters between phases or motors. This significantly reduces the software timing overhead. All four op amps and four out of five comparators are used for this application.
