DSPIC33CK128MP203-I/M5 General Description

Microchip’s dsPIC33CK family of digital signal controllers (DSCs) features a 100 MHz dsPIC® DSC core with integrated DSP and enhanced on-chip peripherals. These DSCs enable the design of digital power, motor control, advanced sensing and control, high-performance general-purpose and robust applications.

The DSCs simplify the design of high-performance, precision motor control systems that are more energy efficient, quieter in operation and provide extended motor life. They can be used to control BLDC, PMSM, ACIM, SR and stepper motors.

In the digital power segment, this family of devices is ideal for designing switched mode power supplies such as AC/DC, DC/DC, UPS and PFC, providing high-precision digital control of Buck, Boost, Fly-Back, Half-Bridge, Full-Bridge, LLC and other power circuits to reach the highest possible energy efficiency.

The DSCs feature advanced analog for advanced sensor interfacing designs. Offering real-time deterministic performance, the DSCs enable high-performance control applications. The rich feature set in this family of devices also make this family a very good fit for high-performance general-purpose and robust applications.

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.
