Overview

The DSPIC33CH128MP508-I/PT is a high-performance dual-core 16-bit digital signal controller featuring a Master core and a Slave core designed to operate independently. This architecture allows for the separation of time-critical control loops from communication and housekeeping tasks, achieving up to 200 MHz performance for the Slave and 180 MHz for the Master.

Why Choose This Part

The dual-core architecture enables seamless LiveUpdate of firmware in the Slave core without interrupting the Master core operation. It features high-speed ADCs and four 12-bit DACs for precise analog control, along with a hardware-based inter-core communication interface that minimizes latency between processors.

Applications

High-Efficiency Power Conversion
Utilizes dual cores to manage complex PFC (Power Factor Correction) and DC/DC conversion stages simultaneously in digital power supplies.
Advanced Motor Control
The Slave core handles high-speed FOC (Field Oriented Control) loops while the Master core manages CANbus communication and system diagnostics.
Automotive Functional Safety
Designed for ISO 26262 applications where hardware redundancy and dedicated functional safety features are required for critical vehicle systems.
Industrial Automation
Ideal for multi-axis robotic controllers and high-speed sensor processing where low latency and deterministic execution are vital.
