Part Verification and Datasheet Update

flux

I can take care of the part audit and metadata cleanup for this part project.
Here’s the current audit snapshot, using the datasheet-sync workflow as the reference process for part verification and property updates :
Current state

Table

CategoryFindings
Project propertiesPresent: Manufacturer Part Number = MCP4431-103E/ST, Designator Prefix = U
Missing project metadataNo Datasheet URL, no Manufacturer Name, no package/case property, no explicit part type, no richer description found
Symbol pin count20 terminals present
Footprint pad count20 pads present
Package evidence in projectFootprint asset MCP4431-103E_ST.kicad_mod, 3D model TSSOP20_MC_MCH.step
Part family evidence from official/vendor pagesQuad I2C digital potentiometer, 20-lead TSSOP, -40°C to +125°C
What looks correct

Table

CheckStatus
Pin count vs footprint pad countLooks consistent at 20 ↔ 20
Package style in projectLooks consistent with TSSOP-20
Main pin names presentThe project includes P3A, P3W, P3B, HVC/A0, SCL, SDA, VSS, VDD, NC, *RESET and the four potentiometer channel groups
Mismatches / gaps I found

Table

AreaIssue
Datasheet propertyMissing
Project metadataManufacturer, package/case, part type, and description appear incomplete/missing
Pin typingAll terminals currently have Pin Type = Unspecified, including VDD, VSS, SCL, SDA, and NC
Pin descriptionsNo pin descriptions were visible on the terminals
Datasheet cross-check completenessI found the official Microchip product page, but I have not yet confirmed the exact canonical PDF URL from Microchip itself, so the final pin-by-pin textual verification against the official PDF is still pending
Key specs identified so far

Table

SpecValue
Device typeQuad digital potentiometer
InterfaceI2C
VariantVolatile
Resistance option10 kOhm (103)
PackageTSSOP-20
Temperature range-40°C to +125°C
The next step is to populate the missing datasheet/property metadata and then normalize the terminal metadata so the symbol matches datasheet intent exactly, which is the recommended flow for part-project verification .
