Looking for "Extract the complete pin table for LCD-S401M16KR including pin number, pin name, and pin function. Also report manufacturer, exact part number, package/mechanical style, display type, viewing mode, backlight, duty/bias, operating voltage, operating temperature, storage temperature, and any mechanical dimensions shown." in LCD-S401M16KR.pdf

Looking for "Summarize the key product description and mechanical/package information for LCD-S401M16KR. Include digit count, segment style, character height if present, display mode, reflective/transflective, and number of pins." in LCD-S401M16KR.pdf

Looking for "What are the names/functions of pins 1 through 12 for LCD-S401M16KR? Return the pin table exactly as shown." in LCD-S401M16KR.pdf

Looking for "Find text near 'PIN 1 2 3 4 5 6 7 8 9 10 11 12' and extract the corresponding pin names/functions for LCD-S401M16KR." in LCD-S401M16KR.pdf

Analyzing symbol and footprint data.

Done - I reviewed the part project and updated the missing Datasheet URL to the official Lumex PDF.

The part-project sync guidance says the datasheet should be treated as the source of truth, the pin count must match exactly, and pin metadata should be populated from the datasheet rather than left generic
Cross-check results 1) Schematic symbol
  • Pass: the symbol has 12 terminals, which matches the datasheet's 12 pins.
  • Mismatch / incomplete data: all terminals are currently just generic numbered terminals with:
    • no pin names
    • no pin descriptions
    • all pin types set to Bi-Directional
  • That means the symbol is structurally the right size, but semantically incomplete versus the datasheet. The sync rules specifically call for exact datasheet-derived pin numbers, names, and functions rather than generic placeholders
2) Footprint
  • Pass: the footprint has 12 pads, so the pad count matches the symbol and datasheet.
  • Likely okay mechanically: the attached footprint/3D model assets exist, and the part dimensions line up with the published package/module dimensions.
  • Limitation: I could not extract the exact pad numbering/order or the full pin-function table from the PDF automatically, so I could not conclusively verify pad-to-pin naming/orientation mapping.
3) Pin descriptions
  • Mismatch: there are currently no pin descriptions in the part project.
  • Mismatch: all pins are marked Bi-Directional, which is unlikely to be correct for an LCD glass module because these pins usually have specific COM/SEG drive roles rather than generic bidirectional behavior.
  • Per the sync workflow, missing pin names/descriptions/types should be treated as incomplete metadata that needs to be filled from the datasheet pin table

Summary of issues to flag

AreaResultNotes
Datasheet URLFixedOfficial Lumex PDF added
Pin countGood12 symbol terminals / 12 footprint pads / 12 datasheet pins
Pin namesMissingSymbol terminals are unnamed generics
Pin descriptionsMissingNo functional descriptions present
Pin typesLikely wrongAll set to Bi-Directional
Package propertyMissingShould be added as a project property
Manufacturer propertyMissingShould be added as a project property
Recommended next step
The remaining gap is the exact 12-pin function table. Once that is extracted cleanly from the datasheet, I can finish the audit by:
  • naming each terminal,
  • setting correct pin descriptions,
  • assigning more accurate pin types,
  • and verifying footprint pad numbering against the symbol.
If you want, I can do that next and populate the missing pin metadata directly.
