PIC24EP256MC202-E/SP

Microcontrollers Overview

The PIC24EP256MC202-E/SP is a 16-bit microcontroller from the PIC24EPXXXMC20X family, featuring 256 Kbytes of program flash memory and 32 Kbytes of RAM. It operates at up to 70 MIPS within a 3.0V to 3.6V supply range and supports industrial temperatures (-40°C to +85°C). The device includes high-speed PWM, op amps, comparators, CTMU, DMA, ECAN, UART, SPI, and I2C interfaces in a 28-pin SPDIP package.

Microcontrollers Feature Summary

• Motor control optimized with high-speed PWM and quadrature encoder interface
• Advanced analog capabilities including configurable ADC, op amps, and CTMU
• Flexible peripheral pin select for digital function remapping
• Robust communication support via ECAN, dual UART, SPI, and I2C modules

Microcontrollers Applications

• Brushless DC (BLDC) motor drives
• Permanent magnet synchronous motor (PMSM) control
• AC induction motor (ACIM) applications
• Switched reluctance motor (SRM) systems
• Industrial power conversion and inverters

Microcontrollers Procurement Notes

Verify the specific suffix '-E/SP' against official Microchip documentation to confirm the extended temperature grade and SPDIP package type. Ensure compatibility with existing board layouts due to the 28-pin form factor. Cross-reference silicon errata for any known revisions affecting the MC20X series before finalizing procurement plans.

Microcontrollers Selection Notes

Select this part when 256 Kbytes of flash and 32 Kbytes of RAM are required for complex motor control algorithms. The MC20X variant is preferred over GP20X for dedicated motor control peripherals like PTG and QEI. Verify that the 28-pin SPDIP package meets mechanical constraints and thermal requirements for the target enclosure design.

Microcontrollers Part Context

This component belongs to the PIC24EPXXXMC20X motor control family within the broader dsPIC33E/PIC24E ecosystem. It shares architectural similarities with dsPIC33E devices but offers optimized peripherals for motion control. The MC20X designation specifically indicates the inclusion of advanced motor control features compared to general-purpose variants.

Microcontrollers Replacement Considerations

Direct substitutes include other PIC24EP256MC202 variants with different packages (e.g., SOIC, SSOP, QFN-S) or temperature grades. For functional equivalents, consider dsPIC33EP32MC202 if reduced memory suffices, though pinouts and peripheral availability may differ.
