Overview

The DSPIC33EP128GP504-I/PT is a high-performance 16-bit Digital Signal Controller (DSC) that combines the control of a microcontroller with the signal processing capabilities of a DSP. Operating at 70 MIPS, it features 128KB of Flash memory and specialized hardware for high-speed PWM and motor control applications. This device is specifically designed for real-time control loops requiring high precision and integrated analog peripherals like op-amps and comparators.

Why Choose This Part

This DSC offers two 40-bit accumulators and single-cycle MAC instructions, providing efficient DSP performance without the complexity of a 32-bit architecture. Its high-speed PWM resolution of 7.14 ns and integrated analog peripherals significantly reduce PCB footprint in power and motion control designs.

Applications

Brushless DC (BLDC) Motor Control
Utilizes the high-speed PWM with 7.14 ns resolution and integrated op-amps for precise rotor position sensing and phase current control.
Industrial CAN Communication
Integrated CANbus interface allows for robust networking in industrial automation and vehicle subsystem monitoring.
Digital Power Conversion
The fast ADC (up to 1.1 Msps) and flexible trigger configurations enable tight control loops for DC/DC converters and UPS systems.
Sensor Signal Conditioning
On-chip analog comparators and operational amplifiers reduce external component count for processing low-level industrial sensor signals.
