Microchip’s dsPIC33CK single-core Digital Signal Controllers (DSCs) accelerate Digital Signal Processor (DSP) performance for time-critical applications. This family offers fast deterministic performance to address real-world design requirements such as high energy efficiency across variable load conditions in a power supply or controlling the precise speed and rotation of a motor. Complementing the dsPIC33CH dual-core DSCs, the dsPIC33CK family offers a cost-effective single-core option with the same high-performance core and peripherals.  

These high-performance DSCs feature a dsPIC33 ‘C’ core with DSP engine, expanded context selected registers to reduce interrupt latency, new instructions to accelerate DSP performance, tightly coupled peripherals and faster execution to enable complex high-speed control loop implementation. The dsPIC33CK family maintains the simplicity of a microcontroller and provides a performance upgrade path for dsPIC33E/dsPIC33F DSC users.
