Microchip dsPIC33A Digital Signal Processors

The dsPIC33A family of DSCs with low latency responsiveness is designed for high-performance and real-time precision control applications. These DSCs combine the advantages of MCUs with the signal processing capabilities of Digital Signal Processors (DSPs), making them suitable for a wide variety of applications that require quick control loop computations using multiple sensor inputs.

Introducing the first family dsPIC33AK128MC1xx DSCs which includes up to 128 KB Flash and an extensive peripheral set, offered in various packages, including SSOP, VQFN and TQFP options ranging from 28 to 64 pins, with package dimensions as small as at 4 × 4 mm. Future dsPIC33A families with additional memory, peripherals and larger pin counts will complete the portfolio.
