DSPIC33EP32GS504T-E/ML

Microcontrollers Overview

The dsPIC33EP32GS504T-E/ML is a 16-bit Digital Signal Controller from the dsPIC33EPXXGS50X family, manufactured by Microchip Technology. It features a 16-bit dsPIC33E CPU with dual 40-bit accumulators and single-cycle MAC operations. The device includes 32 KB of Flash program memory and 4 KB of RAM. Operating at up to 70 MIPS within a 3.0V to 3.6V supply range, it supports extended industrial temperatures (-40°C to +125°C). Key peripherals include five high-speed PWM generators, a 12-bit ADC with four dedicated cores, two Programmable Gain Amplifiers, and four analog comparators. Communication interfaces consist of two UARTs, two SPI modules, and two I2C modules. It is housed in a 44-pin QFN package.

Microcontrollers Feature Summary

• High-performance 16-bit DSP architecture with code-efficient instruction set and dual working register sets
• Advanced analog subsystem featuring configurable resolution ADC cores and rail-to-rail comparators with integrated DACs

Microcontrollers Applications

• AC/DC and DC/DC power converters
• Solar inverters and PFC circuits
• Lighting control systems

Microcontrollers Procurement Notes

Verify the specific ordering suffix '/ML' corresponds to the 44-lead QFN package and tape-and-reel shipping configuration. Confirm that the '-E' suffix indicates the extended temperature grade suitable for -40°C to +125°C operation. Ensure compatibility with AEC-Q100 Grade 1 requirements if automotive qualification is necessary for the target application environment.

Microcontrollers Selection Notes

Select this component when designing digital power supplies requiring tight integration between control loops and analog sensing. The interconnected SMPS peripherals allow for cycle-by-cycle current mode control without excessive CPU intervention. Consider the 44-pin QFN form factor for compact PCB layouts where multiple PWM outputs and analog inputs are required simultaneously.

Microcontrollers Part Context

This device belongs to the dsPIC33EPXXGS50X family, which is optimized for digital power applications. Unlike general-purpose DSCs, this series emphasizes the interconnection between PWM triggers, ADC conversions, and comparator responses to minimize latency in power management control loops.
