Part Datasheet Review and Verification

flux

I reviewed the part project against the available project data and the datasheet-sync criteria. The recommended review flow for a part project is: verify the Datasheet URL, extract authoritative pin/package/spec data from the datasheet, then compare that against all terminal elements and project metadata
What I verified Project metadata
  • Manufacturer Name: STMicroelectronics
  • Manufacturer Part Number: CLT01-38SQ7
  • Designator Prefix: IC
  • Datasheet URL: already present, so no Datasheet property update was needed. The sync guidance says to update this only when the property is missing or empty
Schematic symbol structure
  • The part project contains 49 terminal components total.
  • That count is structurally consistent with a 48-pin QFN plus exposed pad, which is exactly the kind of check the datasheet-sync process requires because exposed pads must be counted as pins too
  • The symbol currently has no nets, which is normal for a part-definition project.
Footprint structure
  • The footprint asset is a 7 mm x 7 mm QFN-style footprint with:
    • 48 perimeter pads
    • 1 large center exposed pad
    • Total 49 pads
  • That is consistent with the package naming in the footprint asset and with public package references for this part family showing 48-QFN / exposed pad, 7 x 7 mm.
Key specs I could confirm
From the official/public ST product results:
  • Part: CLT01-38SQ7
  • Function: high speed digital input current limiter / octal industrial digital input IC
  • Channel count: 8
  • Package: QFN-48, 7 mm x 7 mm, exposed pad
  • Application class: industrial digital input interface, IEC 61131-2 oriented
  • Public search results also indicate a 15 V to 35 V operating range on distributor listings for this device family.

Issues that need attention

Table

AreaStatusIssue
Pin TypeMismatch / incompleteAll 49 terminals are still Unspecified
Pin DescriptionIncompleteNo datasheet-derived pin descriptions are populated
Section / Pin Group / OrientationIncompleteThese IC-style symbol organization properties are not populated
Datasheet-level pin-function validationNot fully completedI could not extract the pin table text directly from the configured PDF URL in this session
The datasheet-sync guidance is explicit that IC-style part terminals should have correct Pin Type, and usually also Section, Pin Group, Pin Orientation, and for larger parts potentially sub-symbol grouping
Main flag
The biggest concrete problem is that the symbol is only structurally complete, not semantically complete:
  • all pins exist
  • the footprint pad count matches
  • but every pin is still untyped, which degrades ERC/usefulness and falls short of a proper datasheet-synced part project
Bottom line
  • No Datasheet property update was required.
  • MPN, manufacturer, overall package style, and pin-count structure look correct.
  • Footprint and symbol pad/terminal counts match at 49 total connections including the exposed pad.
  • The part is not fully verified yet at the pin-function level, because the terminal metadata is still incomplete:
    • Pin Type: missing on all pins
    • Pin Description: missing
    • Symbol organization properties: missing
If you want, I can do the next pass and populate the terminal properties from the datasheet pin table so the part becomes fully datasheet-synced.
