Microchip’s dsPIC33CH family of digital signal controllers (DSCs) feature dual 90 & 100 MIPS 16-bit dsPIC® DSC cores with integrated DSP and enhanced on-chip peripherals. These DSCs enable 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. These DSCs enable the design of 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.  These devices are also ideal for many advanced sensing and control, touch, high-performance general-purpose and robust applications.

These dual-core DSCs are a good fit for complex yet cost-effective advanced sensing, core-independent touch, motor, and digital power applications.

The dsPIC33CH product family has many hardware features that help simplify functional safety certifications for ASIL-B/-C and SIL-2/-3 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.
