The PIC32CM series of 5 V Cortex-M0+ microcontrollers (MCUs) extends Microchip Technology's current SAMC2x portfolio with cost-efficient options, including 64 KB and 128 KB Flash options, 16 KB RAM, and PDEC positional decoders for motor control applications. These products feature robust communications peripherals, including the SERCOM module and LIN, along with advanced motor control peripherals. These devices operate from a true 5 V supply (2.7 V to 5.5 V), offering increased robustness in applications such as home appliance motor control by increasing the dynamic range of the ADC above the common noise floor. Application demo code, including sensorless FOC motor control, is available via the motor control library featured in Harmony version 3, supported by MPLAB® X IDE and MPLAB Harmony. In addition, external tools from vendors KEIL and IAR are also supported. The PIC32CM family of MCUs is ideal for consumer, commercial, industrial, and automotive applications in noisy environments.
