dsPIC33 Digital Signal Controllers for Advanced Motor Control

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.

Motor Control Features

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

Motor Control Peripherals and High Analog Integration

High-speed center/edge-aligned complementary Pulse-Width Modulation (PWM) outputs with dead-time insertion and compensation; control inputs for fault overrides and synchronization
- Up to 24 channels of high-speed PWM outputs enable simultaneous control of up to four three-phase motors
- 16 to 20 bits of digital resolution to support a wide range of PWM switching frequencies
- Fine Edge Placement (FEP) module provides up to 78 ps of edge placement resolution
High-speed, 12-bit Analog-to-Digital Converters (ADCs) with oversampling, filters, digital comparators and multiple sample-and-hold circuits
Differential high-speed analog comparators, with 12-bit programmable Digital-to-Analog Converters (DACs) and high-bandwidth differential op amps
The high-speed analog peripherals of dsPIC33A DSCs include:
- Up to five 40 Msps ADCs that reduce control loop execution time, resulting in less control phase lag
- Rail-to-rail, 100 MHz bandwidth, 100 V/µs slew rate, unity-gain stable op amps with 1 mV typical voltage offsets to improve phase current measurements, and running user calibration to further decrease the offset voltage
- V_DD/2 buffered voltage output for op amp biasing eliminates the need for an external op amp divider circuit, which saves board space and Bill of Materials (BoM) cost
- 5 ns analog comparator propagation delay to disable PWM outputs faster in an overcurrent situation
Real-time control peripherals such as the PWMs, ADCs, op amps and comparators are tightly coupled for fast and predictable control loops without CPU software intervention
The Quadrature Encoder Interface (QEI) provides classic ABZ incremental encoder support to track rotor position and speed; and four digital filters improve transition detection in noisy environments
The Bidirectional Serial Synchronous (BiSS) encoder interface offers a more robust communication method, effective for distances up to 100 meters; the host module supports four daisy-chained client encoders
High level of integration for lower BoM cost

Functional Safety Support
