Part Data Review and Validation
Worked for 3 mins 50 sec
Completed the PT2272M4 review and added the best available Princeton datasheet URL:
https://www.mouser.com/datasheet/2/737/PT2272-2489449.pdf.The symbol pin numbers/names match the datasheet, and the DIP-18 footprint matches the PT2272-M4 DIP package option. Main issues flagged: package property is incorrectly set to
TO, pin descriptions are missing, and pin electrical types are all unspecified; details are in the project document pt2272m4-part-review.
Fix the package property, pin descriptions, and electrical pin types from the datasheet.
Thought for 9 sec
I’ll update the part/package metadata and annotate each terminal with datasheet-based pin descriptions and electrical pin types, then re-read the schematic to verify.
Thought for 1 min 31 sec
Updated and verified the PT2272M4 part metadata:
Package or Case Code is now 18-DIP.All 18 pins now have datasheet-based
Pin Description values and valid electrical Pin Type settings: A0–A7/DIN = Input, D0–D3/VT = Output, OSC1/OSC2 = Passive, VSS = Ground, VCC = Power In. No open items remain.Run part checks

Footprint cross-check
- Datasheet package for PT2272-M4: 18-pin DIP;
-S18indicates 18-pin SO option. - Project footprint asset:
DIP794W56P254L2286H533Q18N.kicad_mod. - Interpretation: DIP, 7.94 mm body/row span, 2.54 mm pitch, 22.86 mm body length, 18 pins.
- Result: footprint is consistent with the 18-pin DIP package option for PT2272-M4.
Mismatches / issues flagged
- Package property mismatch: project property
Package or Case Codeis set toTO, but the datasheet lists PT2272-M4 as an 18-pin DIP or 18-pin SO (-S18). The assigned footprint is DIP, so the package property should be corrected to DIP-18 / PDIP-18 rather than TO. - Pin descriptions missing: all 18 terminals have only
Pin Type: Unspecified; noPin Descriptionvalues are populated. The pin numbers and names match the datasheet, but descriptions should be added for clarity. - Electrical pin types are unspecified: VCC/VSS should be power pins, D0-D3 and VT outputs, DIN input, A0-A7 tri-state address inputs, OSC1/OSC2 oscillator pins.
- Datasheet URL storage note: the URL was added as
Datasheet URLat project level, but the platform reported it as a non-standard project property name. The URL is present, but if this part publication has a canonical part-level datasheet field, it should ideally be migrated there.
