dsPIC33 DSCs for Motor Control Applications
Our dsPIC® Digital Signal Controllers (DSCs) combine the performance of a Digital Signal Processor (DSP) engine and the versatile peripherals of a microcontroller (MCU). This combination enables you to implement advanced motor control solutions. dsPIC33 motor control DSCs offer specialized peripherals to meet the needs of a variety of high-performance motor control applications. For example, our sensorless Field-Oriented Control (FOC) algorithm makes use of a single-cycle MAC with data saturation, zero overhead looping and barrel shifting for exceptional performance and precision speed, position and torque control.
Discover how dsPIC DSCs with our ecosystem of development tools, software and other design resources make it easy to develop your next Brushed DC (BDC) motor, Brushless DC (BLDC) motor, Stepper Motor, Permanent Magnet Synchronous Motor (PMSM) or AC Induction Motor (ACIM) application.

High-Performance dsPIC33 DSC Core
- The high-performance 200 MHz, 32-bit dsPIC33A DSCs with a single-/dual-precision FPU coprocessor eliminate the need to scale variables, reducing user software errors, and the sine and cosine instructions in the FPU decrease motor control loop execution time
- The single- and dual-core dsPIC33C DSCs operate at up to 100 MHz/core with a DSP instruction set and a modified Harvard architecture for implementing fast control loops
- The dual-core architecture provides a secondary core dedicated for executing time-critical motor control algorithms and a primary core dedicated for implementing system monitoring, user interface and communication functions or to control a second motor
- Rich instruction set and addressing modes designed for real-time control where most instructions are single cycle
- Dual 40-bit (dsPIC33C)/72-bit (dsPIC33A) accumulators to implement single-cycle MAC instructions
- Full-speed operation from Flash without added wait states
- Multiple context registers and accumulators for fast interrupt switching
