Microcontrollers Procurement Notes

Verify the specific suffix 'I/PF' against official Microchip documentation to confirm the exact package type and temperature rating. Ensure compatibility with required voltage levels and operating conditions. Confirm availability through authorized distributors as supply status may vary. Check for any silicon errata or data sheet clarifications relevant to this specific revision before finalizing procurement.

Microcontrollers Selection Notes

Select this component when a balance of moderate flash capacity and robust connectivity is required. The 50 MHz performance suits applications needing efficient code execution without the complexity of higher-end cores. Consider the 100-pin TQFP package for sufficient I/O density in space-constrained designs. Evaluate power consumption requirements against the specified low-power modes if battery operation is intended.

Microcontrollers Part Context

This device belongs to the PIC32MX1XX/2XX/5XX 64/100-pin family, designed for general-purpose embedded applications. It offers a cost-effective solution combining 32-bit performance with rich peripheral integration. The series supports migration from 16-bit architectures due to pin compatibility with certain PIC24/dsPIC devices.
