Microchip DSPIC33CK128MC103T-I/M5

Microchip’s dsPIC33CK256MC50X 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, high-performance, general embedded and robust applications in automotive, industrial, medical and consumer segments.

In the motor control segment, this family is well suited for cost competitive automotive, consumer and industrial applications. The dsPIC33CK256MC50X family of DSCs is ideal for the control of BLDC, PMSM, ACIM, SR and stepper motors. The high level of peripheral integration on the dsPIC33CK256MC50X DSCs enables applications to implement power factor correction (PFC) and Field Oriented Motor Control (FOC) using a single DSC.

Loaded with advanced analog peripherals such as high-performance 12-bit ADCs and 12-bit DACs, high-speed analog comparators, and op amps, dsPIC33CK256MC50X family of DSCs provides simple-to-use smart sensor interfaces for various electronic sensing applications. The rich feature set and the 150°C high-temperature rating available on this DSC family make it a very good fit for automotive sensors and industrial automation.

The Functional Safety Ready dsPIC33CK product family has many features and a comprehensive safety ecosystem that help simplify the design of safety-critical applications and achieve functional safety certification. Learn more about Functional Safety Readiness including hardware, software, and supporting collateral, visit https://www.microchip.com/en-us/products/microcontrollers-and-microprocessors/dspic-dscs/functional-safety.
