DSPIC33EP64GP502-E/SP

Microcontrollers Overview

The DSPIC33EP64GP502-E/SP is a 16-bit digital signal controller from the dsPIC33EP family, manufactured by Microchip Technology. It features a single-core architecture with 64 KB of program Flash memory and 8 KB of data RAM. The device operates on a supply voltage range of 3.0V to 3.6V and supports clock frequencies up to 70 MIPS at industrial temperatures (-40°C to +85°C). It utilizes a 28-pin SPDIP package for through-hole mounting.

Microcontrollers Feature Summary

• Features a high-performance 16-bit dsPIC33E CPU with modified Harvard architecture and dual 40-bit accumulators for efficient digital signal processing.
• Includes advanced analog peripherals such as a configurable ADC, op amps/comparators, and a Charge Time Measurement Unit (CTMU) for capacitive touch sensing.
• Provides flexible communication interfaces including UART, SPI, I2C, and an ECAN module with support for CAN 2.0B protocols.
• Supports motor control applications with high-speed PWM modules featuring independent timing and programmable fault inputs.

Microcontrollers Applications

• Industrial motor control systems
• Digital power conversion and inverters
• Capacitive touch sensing interfaces
• Communication gateways using CAN or serial protocols

Microcontrollers Procurement Notes

Verify the specific ordering suffix 'I' indicates the industrial temperature range (-40°C to +85°C), while 'E' denotes extended range capabilities if applicable to the variant. Confirm the SPDIP package designation matches the required through-hole form factor. Ensure compatibility with the 3.0V to 3.6V operating voltage range for the target system design.

Microcontrollers Selection Notes

Select this component when a balance of DSP performance and general-purpose MCU features is required in a 28-pin package. Consider the 64 KB Flash size for moderate code complexity and the availability of dedicated motor control peripherals like PWM and CTMU. Evaluate the need for CAN connectivity and analog front-end integration before choosing over simpler PIC24 devices.

Microcontrollers Part Context

This device belongs to the dsPIC33EPXXXGP50X general-purpose family within the broader dsPIC33E ecosystem. It shares architectural similarities with the MC20X/MC50X motor control variants but lacks specific motor control PWM channels found in those families. The GP502 designation identifies it as a 64 KB Flash, 8 KB RAM device in the 28-pin configuration.

Microcontrollers Replacement Considerations

Direct replacements within the same family include other dsPIC33EP64GP502 variants with different packages (e.g., SOIC, SSOP, QFN-S). For pin-compatible upgrades, consider devices with larger memory sizes such as the dsPIC33EP128GP502, provided the additional resources fit the application requirements.
