Microchip dsPIC33CK64MC105 Digital Signal Controllers

High-performance DSC for industrial, consumer and automotive applications

Microchip’s dsPIC33CK64MC10X family of Digital Signal Controllers (DSCs) features a single 100 MHz dsPIC® DSC core with integrated DSP and enhanced on-chip peripherals. These DSCs enable the design of motor control, advanced sensing and control, touch, general purpose high-performance and robust applications.

In the motor control segment, the dsPIC33CK64MC10X group is well suited for cost competitive automotive, consumer and industrial applications. The dsPIC33CK64MC105 family of DSCs are ideal for the control of BLDC, PMSM, ACIM, SR and stepper motors. The high level of peripheral integration on the dsPIC33CK64MC105 enable applications to implement power factor correction (PFC) and Motor Control using a single DSC.

Loaded with intelligent analog peripherals, such as high-performance ADCs and DACs, high-speed comparators, and op amps, the Microchip dsPIC33CK64MC10X family of DSCs provide simple-to-use smart sensor interfaces for various electronic sensing applications. The rich feature set and 150°C high-temperature rating available on this DSC family make it a very good fit for automotive sensors and industrial automation.

The dsPIC33CK product family has many hardware features that help simplify functional safety certifications for ASIL-B and SIL-2 focused automotive and industrial safety-critical applications. The family offers ISO 26262 and IEC 61508 Functional Safety packages containing FMEDA report, safety manual, diagnostic libraries and more.
