dsPIC33CK Single-Core Digital Signal Controllers

Real-Time Performance for Motor Control, Digital Power, Safety-Critical and High-Performance Embedded Applications

Our single-core dsPIC33CK 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. Complementing our dual-core dsPIC33CH 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 and dsPIC33F DSC users.
