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.
I’ll review the current part metadata, find and attach the official datasheet if needed, then compare symbol pins/footprint/details against it and summarize any mismatches.
Completed the STTS22HTR review. The official ST datasheet was already set, and the MPN, pin numbering, and UDFN-6L footprint concept match the datasheet.
Open items flagged:
Pin Type values are all Unspecified.
Pin Description properties are missing.
Package or Case Code = UDFN-6L is not explicitly set.
ALERT_/_INT is functionally correct but stylistically differs from datasheet ALERT / INT.
Improves temperature match with surrounding environment
EP, Pin Number 7
Reasonable footprint pad, but no pin description/type set
Footprint cross-check
Project footprint asset: SON65P200X200X55-7N-D.kicad_mod, described as UDFN-6L.
Footprint pad geometry from project asset:
Pads 1-6: 0.30 mm x 0.80 mm, 0.65 mm pitch, three pads per side
Pad 7 / EP: 0.75 mm x 1.55 mm center exposed pad
Fab outline: 2.0 mm x 2.0 mm body with pin-1 chamfer
Courtyard: approximately 3.25 mm x 2.55 mm
3D model: STTS22HTR.stp
Datasheet package / land pattern information extracted:
Package: UDFN-6L, 2.0 mm x 2.0 mm x 0.50 mm, exposed pad down
Package body: 2.0 mm length +/-0.05, 2.0 mm width +/-0.05, 0.55 mm max height
Lead pitch: 0.65 mm
Lead geometry callouts include 0.25 mm +/-0.05 and 0.4 mm +/-0.1 for the 6 leads
Exposed pad / central land callout: 1.45 mm +/-0.1 in package drawing
Land pattern extracted callouts include 1.45, 1.78, 0.65, 0.7, and 0.27 mm
Solder mask opening extracted callouts include 1.77, 0.47, 2.68, 0.9, 0.88, and 1.65 mm
Footprint result: broadly consistent with a 2.0 x 2.0 mm, 0.65 mm pitch UDFN-6L with exposed pad. The project footprint’s 0.30 mm x 0.80 mm lead pads and 0.75 mm x 1.55 mm EP pad are plausible against the extracted datasheet land pattern values, though the datasheet OCR did not provide a fully labeled dimension table for every land-pattern feature. Critical manufacturing release should still verify directly against Figure 10 / Figure 11 in the PDF.
Mismatches / issues flagged
Schematic terminal Pin Type values are all Unspecified; datasheet-backed types should be set for better ERC/search quality:
SCL: Input or Digital / I2C clock
SDA: Bi-Directional / I2C data
ALERT_/_INT: Open-drain output
VDD: Power In
GND: Ground
ADDR: Input
EP: Passive or thermal/mechanical pad, typically tied according to the recommended footprint/application practice if specified elsewhere
Pin Description properties are absent from the terminals; the datasheet pin functions should be added.
ALERT_/_INT name is functionally correct, but differs stylistically from the datasheet spelling ALERT / INT.
The datasheet has 6 electrical leads plus an exposed pad; the project exposes this as a 7th schematic terminal/pad EP. That is reasonable for layout/control, but it should have a clear description and type.
The project metadata does not explicitly include Package or Case Code = UDFN-6L; adding it would improve BOM/search clarity.
Project Part Type is Sensors; the datasheet-specific classification is more precisely a digital temperature sensor.
Overall conclusion
The part identity, datasheet URL, pin numbering, and UDFN-6L footprint concept match the STMicroelectronics datasheet. The main cleanup needed is metadata enrichment: add pin descriptions, assign proper pin types, optionally add the package case code, and optionally normalize the ALERT/INT label formatting.
