Part Data Review and Update

flux

I reviewed the part project, corrected the datasheet link, and cross-checked the current metadata, symbol, and footprint against the LMS7002M datasheet. I followed the standard part-project audit flow of verifying the datasheet URL first, then checking metadata and terminal data against the datasheet pin/package info
Updated
  • I updated Datasheet URL to:
    • https://www.mouser.com/datasheet/2/982/LMS7002M-Data-Sheet-v3.1r00-1600568.pdf
Key specs confirmed from the datasheet

What matches
  • MPN matches: LMS7002M
  • Footprint naming is broadly consistent with the datasheet package:
    • current footprint: AQFN261_11P5X11P5_LIM
    • datasheet: 261-pin aQFN, 11.5 mm x 11.5 mm
  • Terminal count structure is broadly in-family for this package.
  • The symbol is already split into 3 sub-symbols, which is reasonable for a large RF IC.
Mismatches / issues flagged

Datasheet propertyThe previous datasheet link appeared to point to a different part; now correctedHigh
Project descriptionCurrent description reads more like a long marketing summary and includes wording like cellular/module language that does not cleanly match a concise IC part descriptionMedium
Package metadataI did not find a populated Package or Case Code project property, even though the datasheet clearly gives 261-pin aQFN, 11.5 x 11.5 mmMedium
Pin descriptionsNone of the terminals appear to have Pin Description populatedHigh
Ground pin typingSeveral ground-related terminals are typed as Power Out instead of GroundHigh
Numbering consistencyThe project mixes alphanumeric package coordinates with a numeric 262 pin for GND; datasheet package is 261-pinHigh
Symbol grouping qualitySub-symbols exist, but they are generic (LMS7002M_1_1, etc.) rather than functional groupsLow

Symbol / terminal audit summary
  • Total terminals: 261
  • Pin Number populated: 261/261
  • Pin Type populated: 261/261
  • Pin Description populated: 0/261
  • Sub-symbol count: 3
For IC-style parts, pin descriptions and structured grouping are part of a complete audit target, and every terminal should be checked against the datasheet rather than inferred
Main takeaway
The part is partially well-formed:
  • package family looks right
  • many pin names/numbers are already aligned
  • terminal count is close to the expected package structure
But it still has important quality issues:
  • ground pins mis-typed
  • no pin descriptions
  • inconsistent pin numbering around 262
  • metadata is incomplete/unclear in places
  • project description should be cleaned up
If you want, I can next fix the part metadata and terminal properties:
  • add Package or Case Code
  • rewrite the description
  • convert ground terminals from Power Out to Ground
  • populate concise Pin Description fields for the terminals that need them
Fix metadata and pins
Add package details
Check numbering issue
