Part Metadata Review and Update

flux

I reviewed the part definition for MA2304PNSXUMA1 against the official Infineon PDF already linked in the project, so no Datasheet property update was needed.
Overall result
  • MPN: MA2304PNSXUMA1
  • Manufacturer: Infineon
  • Description in project: Amplifier IC 2-Channel (Stereo) Class D PG-VQFN-40
  • Datasheet source used: Official Infineon datasheet
  • Project package property: VQFN
  • Datasheet package naming: QFN pad-down 40-pin, 6.0 mm x 6.0 mm, 0.5 mm pitch, exposed pad present
  • Symbol/footprint structure found in project: 41 terminals / 41 pads total
    • Interprets as 40 perimeter pins + 1 exposed pad
    • Footprint identifier found: QFN50P600X600X90-41N-D.kicad_mod
Key specs Datasheet-verified key specs

AreaSeverityFinding
Package namingLowProject says VQFN / PG-VQFN-40 style naming, while datasheet text uses QFN pad-down 40-pin. Likely equivalent family naming, but not an exact text match.
Exposed pad naming/numberingMediumDatasheet treats the center pad as EPAD = VSS rather than a numbered signal pin. In the project it is modeled as pin 41 / VSS. This is workable, but it is not the same naming convention as the datasheet.
Pin type metadataMediumAll terminals are currently Pin Type: Unspecified. The datasheet clearly implies power, ground, input, output, bidirectional/open-drain categories.
Pin descriptionsMediumThe project terminals currently show pin numbers, but I did not find datasheet-derived per-pin description properties stored on the symbol terminals.
Package property specificityLowPackage or Case Code = VQFN is generic. The footprint identifier is much more specific than the project property.
Symbol and footprint assessment Symbol
  • The symbol terminal names and numbers appear to match the datasheet well for the main 40 pins.
  • The main issue is metadata completeness, not pin-name correctness:
    • pin types are unspecified
    • terminal descriptions are missing or incomplete
Footprint
  • The footprint appears structurally correct for this device class:
    • 0.5 mm pitch
    • 6 x 6 mm body class
    • 41-pad implementation
  • The footprint identifier QFN50P600X600X90-41N-D is consistent with the datasheet package dimensions.
  • I did not find an obvious footprint-count mismatch.
Recommended cleanup
  1. Change the package/project wording to match the datasheet more closely:
    • from generic VQFN
    • to something like QFN pad-down 40-pin, 6 x 6 mm, EPAD
  2. Rename or annotate the exposed pad so it is clearly understood as:
    • EPAD / VSS
    • rather than only pin 41
  3. Fill in terminal metadata from the datasheet:
    • pin type
    • pin description
    • power/ground classification where applicable
Bottom line
  • No hard pinout mismatch found
  • No datasheet URL update needed
  • Footprint and symbol are broadly consistent with the datasheet
  • The main issues are metadata quality and the EPAD being represented as numbered pin 41 instead of an explicitly named exposed pad
If you want, I can next update the part project metadata and terminal properties to make the symbol/package info fully datasheet-aligned.
