Overview

The DSPIC33FJ128MC804-I/PT is a 16-bit Digital Signal Controller (DSC) optimized for motor control and industrial automation. It combines the processing power of a digital signal processor with the peripheral set of a microcontroller, featuring 128KB of Flash and a dedicated Motor Control PWM peripheral. Operating at 40 MIPS, it provides the deterministic performance required for complex real-time control algorithms.

Why Choose This Part

This DSC offers 8-channel DMA to offload data movement from the CPU, maintaining 40 MIPS throughput for critical math. It features 5V-tolerant I/O pins, simplifying interfacing with legacy industrial logic, and includes a 6-channel 16-bit DAC for high-resolution signal generation.

Applications

Brushless DC (BLDC) Motor Control
Utilizing the 8-channel PWM and Quadrature Encoder Interface (QEI) for precise commutation and speed control.
Industrial Sensor Fusion
Leveraging DSP instructions and the 16-bit ADC to process high-speed analog signals from multiple industrial transducers.
Automotive Power Electronics
Integrating with vehicle networks via the on-chip CAN controller for power conversion and subsystem management.
Uninterruptible Power Supplies (UPS)
Managing high-speed switching and power factor correction (PFC) using fast ADC sampling and high-resolution PWM.
