Part Review and Datasheet Update
Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.
Thought for 4 sec
I’ll review the part metadata and existing symbol/footprint, find and set the official datasheet if missing, then cross-check pins/package against the datasheet and summarize any mismatches.

I found the official ams OSRAM AS7331 datasheet URL. The current part project does not expose a self Datasheet property through the available metadata tool, so I’m continuing the review and will flag that update limitation if it cannot be written directly.

Completed the AS7331-AQFM review and created the detailed report: AS7331-AQFM Part Review.
Key result: symbol pin names/numbers and 16-pad OLGA footprint count match the official ams OSRAM datasheet; no pinout mismatch found. Open items: the Datasheet URL is missing from metadata visible to the datasheet tool and exact pad dimensions could not be verified from the layout readout; official URL to set is

Symbol / pin-type observations
- Pin numbers and pin names match the datasheet pinout.
- Current pin-type choices are broadly acceptable for ERC:
- VSSA, VDDA, VDDD, VSSD as Power In: OK.
- SDA as Bi-Directional: OK, though datasheet specifically calls it digital I/O open-drain.
- SCL, A0, A1, SYN as Input: OK.
- READY as Output: OK, though datasheet notes it can be push-pull or open-drain depending on configuration.
- REXT as Bi-Directional: functionally acceptable, but a more exact description would be Analog I/O / external reference resistor.
Footprint cross-check
- PCB footprint contains 16 pads, matching OLGA16.
- Silkscreen/body outline appears approximately 2.6 mm × 3.65 mm, matching the datasheet package body dimensions.
- Pin-1 marker is present near the package corner.
- The public datasheet gives package contact geometry and body dimensions, but no separate official recommended PCB land-pattern table was found in the searched public sources. The project description indicates an IPC-7351B footprint and 1.19 mm max height, which is consistent with deriving a land pattern from the manufacturer package outline.
- The layout inspection output did not expose individual pad dimensions/coordinates, so the exact pad size/pitch could not be independently verified from tool output. Datasheet contact dimensions found: 0.300 ± 0.050 mm × 0.100 ± 0.050 mm, 0.5 mm repeated pitch/spacing callouts, 0.177 × 45° pin-1 chamfer.
Mismatches / risks flagged
- Datasheet URL is missing from the part metadata visible to the datasheet query tool. Official URL to set: https://look.ams-osram.com/m/1856fd2c69c35605/original/AS7331-Spectral-UVA-B-C-Sensor.pdf
- Exact footprint pad geometry could not be verified because the layout readout did not expose pad coordinates/sizes, even though pad count and outline match.
- Pin descriptions are mostly implicit in terminal names and pin types; richer terminal descriptions could be added for SDA open-drain, READY configurable output, and REXT external 3.3 MΩ resistor if desired.
Verdict
No pinout or package-count mismatch was found. The symbol pin names/numbers and footprint pad count match the official ams OSRAM AS7331-AQFM OLGA16 datasheet. The remaining issues are metadata completeness and exact land-pattern dimensional verification.
