Part Information Review and Update

flux

I reviewed the part against the official datasheet already linked in the project. Since a Datasheet URL property is already present and points to the ams OSRAM PDF, no web search or property update was needed. I used the datasheet as the source of truth for exact pin/name/package checks, which is the right audit method for part projects
Summary Part info audit

Table

FieldIn projectIn datasheetStatus
Manufacturer Part NumberTCS3448Base device name is TCS3448; orderable package codes listed as TCS34488 and TCS34488M- Minor ambiguity
Manufacturer NameOSRAMams OSRAM / OSRAM branding- Acceptable
Part TypeSensors14-channel multi-spectral light sensor- OK
Package or Case CodeTOOLGA-8- Mismatch
Datasheet URLPresentOfficial PDF- OK
Designator PrefixICNot datasheet-driven, but U is the normal IC prefix convention- Convention issue
Description"14-Channel Multi-Spectral Color Sensor..."14-channel multi-spectral light sensor, 380 nm to 1000 nm, I2C 1.2 V/1.8 V, 3.1 mm x 2.0 mm x 1.0 mm package- Mostly OK, could be tightened

Pin property / description audit
This is where most of the issues are.
Current mismatches
  • All 8 terminals currently have Pin Type = Unspecified.
  • No terminal appears to have a Pin Description property populated.
  • No Section, Pin Group, or Pin Orientation properties are present.
  • For part projects, exact pin properties should be checked against the datasheet and not guessed

Footprint cross-check What matches
  • The layout contains 8 pads, consistent with the OLGA-8 package.
  • Pad naming aligns with the 8 symbol terminals.
What I could not fully verify from the available layout data
  • Exact land-pattern dimensions
  • Pad sizes / spacing
  • Package body outline accuracy
  • Pin 1 marker fidelity relative to the datasheet’s recommended PCB pad layout
So, at a minimum:
  • Pad count matches
  • Package property does not match
  • Detailed footprint geometry remains unverified from the current layout tool output alone
Flags Confirmed mismatches
  • Package or Case Code is TO, but datasheet says OLGA-8
  • All terminal Pin Type properties are still Unspecified
  • Terminal Pin Description properties appear to be missing
Likely improvements
  • Manufacturer Part Number could be made more specific if you want an orderable MPN, e.g. TCS34488 or TCS34488M
  • Designator Prefix should probably be U rather than IC
  • Project description could be updated to better reflect the datasheet wording:
    • 14-channel multi-spectral light sensor, 380 nm to 1000 nm, 1.7 V to 1.98 V supply, OLGA-8
If you want, I can make the obvious fixes next:
  • set Package or Case Code to OLGA-8
  • update all 8 terminal pin types
  • add short pin descriptions
  • optionally normalize the MPN and description
