Part Review and Datasheet Validation


Review complete. I created the full report here: W55RP20 Part Review.
  • The part metadata matches W55RP20 / WIZnet and the symbol has the expected 69 pins: QFN68 plus exposed GND pad.
  • Main issues flagged: pin descriptions and electrical pin types are not populated, and the existing datasheet URL appears to be an uploaded older PDF while WIZnet has an official newer v1.0.2 PDF.
  • Footprint pad count matches, but detailed footprint geometry could only be partially verified because the datasheet’s recommended PCB footprint section is marked TBD.
Fix the missing pin descriptions and electrical pin types from the datasheet add also section for all the terminal.
I’ll populate every W55RP20 terminal with the datasheet pin description, electrical pin type, and a functional section, then re-read the schematic to verify the properties were applied.
The first batch applied, but Flux warned that some values were non-standard; I’m normalizing them to the accepted Pin Type/Section options as I finish the rest.
Finished. I populated all 69 W55RP20 terminal pins with datasheet-derived Pin Description, standardized Pin Type, and Section, then verified the schematic properties were present.
Open items:
  • I used Flux-standard Pin Type values where needed, e.g. Power In, Power Out, Bi-Directional, Input, Output, and Ground, rather than raw datasheet labels like AO/AI/PWR.
Suggested next steps:
  1. Update the Datasheet URL to the official WIZnet v1.0.2 PDF.
  2. Re-run a final part review/export check before publishing or using this part in designs.
Update datasheet URL
Run final review
Verify footprint geometry
Check publish readiness
