Microchip dsPIC33CK64MC105 Digital Signal Controller (DSC) Family

Recently-launched 100 MHz high-performance DSC

The Microchip dsPIC33CK64MC105 is a high-performance digital signal controller and part of the broader dsPIC33C DSC family. Loaded with key features such as high-speed ADC, op amps, comparators and high-resolution PWMs, the dsPIC33CK64MC105 controller enables the design of low-cost automotive sensors, industrial automation, motor control and other robust end applications.

In the motor control segment, this digital signal controller family is well suited for cost competitive markets with stringent operating conditions. Features of the dsPIC33CK64MC105 by Microchip include a single 100 MIPS dsPIC® DSC core with integrated DSP and enhanced on-chip peripherals; effective control of BLDC, PMSM, ACIM, SR and stepper motors, in addition to a high level of peripheral integration. The dsPIC33CK64MC105 enables applications to implement power factor correction (PFC) and Motor Control using a single DSC.

The safety-ready Microchip dsPIC33CK64MC10X family of DSCs provide simple-to-use smart sensor interfaces for various electronic sensing applications. The rich feature set combined with an 150°C high-temperature rating make it a very good fit for automotive sensors and industrial automation.
