Part Review and Datasheet Update

Thought for 35 sec

I’ll review the part metadata, find and attach the official datasheet if needed, then compare pins/symbol/footprint against the datasheet and report mismatches.

Reviewed the NJW1194V-TE1 part against the official Nisshinbo datasheet and created the full report here: Part Review: NJW1194V-TE1.

Key findings: all 32 pin numbers/names match the datasheet, but the project package metadata says TO while the datasheet specifies SSOP32, the description’s -40 ~ +125 appears to be storage temperature rather than operating temperature, and pin descriptions/types are not fully populated. Suggested next steps: correct the package metadata to SSOP32, update the description temperature wording, and populate Pin Description / Pin Type properties from the datasheet.

Read the attachment and created the requested terminal-order/section tables here: Terminal Order / Section Table: NJW1194V-TE1.

Short check: all existing terminal names are OK, no required renames, and no uncertain pins found; Power is first and Ground is last as instructed.

Footprint/package cross-check

Layout contains 32 pad nodes, matching the 32-pin datasheet package.
Datasheet mechanical package is SSOP32 with 0.65 mm lead pitch.
Official package drawing lists example land pattern: pad pitch 0.65 mm, pad width 0.35 mm, pad length 1.00 mm, pad row span 7.10 mm, pad array length 9.75 mm.
The visible footprint outline/silkscreen is consistent with a small SSOP/TSSOP-style IC body; detailed pad dimensions were not exposed in the flat layout view for exact numeric verification.

Mismatches / issues flagged

Package metadata mismatch: Project Package or Case Code is TO, but datasheet package is SSOP32. This should be corrected to SSOP32.
Project description temperature ambiguity: Project description says -40 ~ +125; datasheet operating temperature is -40 to +85 °C and storage is -40 to +125 °C. The description appears to mix storage temperature into operating specs.
Pin descriptions missing as properties: Terminals are named correctly, but Pin Description properties are not populated; Pin Type is Unspecified on all terminals.
Datasheet URL consistency: Terminals carry the official Nisshinbo URL, while the project-level Datasheet URL points to an uploaded asset copy. The uploaded copy appears to be the same datasheet, but using the official URL at project level would be clearer if allowed.
Exact land pattern not fully verified: Pad count matches and footprint appears SSOP32-like, but exact pad width/length/spacing should be checked once pad geometry is available/exported.
