DSPIC33EP128MC502-I/SP

Microcontrollers Overview

The dsPIC33EP128MC502-I/SP is a 16-bit Digital Signal Controller from the dsPIC33EP family, manufactured by Microchip Technology. It features a dsPIC33E core with 128 KB of program flash memory and 16 KB of data RAM. The device operates at frequencies up to 60 MIPS within an industrial temperature range of -40°C to +85°C, powered by a 3.0V to 3.6V supply. It is housed in a 28-pin SPDIP package and includes advanced analog peripherals such as op amps, comparators, and a CTMU.

Microcontrollers Feature Summary

• Features a high-performance 16-bit dsPIC33E CPU optimized for code efficiency with single-cycle multiply and accumulate capabilities.
• Includes integrated motor control PWM modules with independent timing and programmable fault inputs for precise drive control.
• Provides flexible analog front-end options with configurable ADCs, operational amplifiers, and comparators connected directly to the ADC module.

Microcontrollers Applications

• Servo motor control systems
• Solar inverters and DC/AC power conversion
• Digital power supplies and lighting controls

Microcontrollers Procurement Notes

Verify the specific ordering suffix '-I/SP' confirms the industrial temperature grade (-40°C to +85°C) and the 28-pin SPDIP through-hole package. Ensure compatibility with existing PCB footprints designed for this specific package style before finalizing procurement orders.

Microcontrollers Selection Notes

Select this component when a 16-bit DSC with integrated motor control PWM and analog peripherals is required in a through-hole package. Compare against the GP502 variant if digital signal processing features like additional DSP instructions are not needed, or choose MC202 variants for different peripheral configurations.

Microcontrollers Part Context

This device belongs to the dsPIC33EPXXXMC20X/50X Motor Control Family. It shares the same core architecture and memory sizes with other devices in the series but differs in peripheral availability and package options. The 'MC' designation indicates its suitability for motor control applications compared to the general-purpose 'GP' family.

Microcontrollers Replacement Considerations

Direct pin-to-pin replacements include other devices within the dsPIC33EP128MC50x series with different packages, such as DSPIC33EP128MC502-I/MM (QFN). Verify that the alternative package meets mechanical constraints and that thermal performance is adequate for the application.
