Microcontrollers Procurement Notes

Verify the specific suffix 'E' indicates the extended industrial temperature range (-40°C to +125°C) and 'SO' denotes the 28-pin SOIC package. Confirm that the datasheet DS30010221C applies to this specific part number within the GP202/GU202 sub-family. Ensure compatibility with required voltage levels and interface configurations before integration.

Microcontrollers Selection Notes

Select this component when a 16-bit architecture with integrated USB OTG is required in a compact 28-pin form factor. It is suitable for designs prioritizing code security through ECC Flash and flexible I/O mapping via PPS. Consider the -E variant for environments requiring extended temperature stability compared to commercial grade options.

Microcontrollers Part Context

This device belongs to the PIC24FJ GU202 series, which offers reduced pin counts and memory sizes compared to the 64KB variants in the same family. It shares the same core CPU and peripheral set as larger members but is optimized for cost-sensitive and space-constrained applications requiring USB connectivity and robust data integrity.
