Microchip Technology DSP Microcontroller The Microchip Technology DsPIC33CH family type TQFP package, surface mount, 80-pin and 16-bit CMOS based DSP microcontroller has a voltage rating that ranges between 3V and 3.6V. It has 32Kbytes to 256K bytes program flash with ECC and 8K to 24K RAM. This enables the design of high-performance, precision motor control systems that are more energy-efficient. This microcontroller is used to control BLDC, PMSM, ACIM, SR and stepper motors quieter in operation and also provides extended motor life. Features and Benefits • 16-bit working registers
