Part Data Review and Mismatch Assessment

flux

I reviewed the part project against the datasheet and current project data.
Overall result
  • The part metadata is partially complete.
  • The project already has a Datasheet URL, so I did not search/update it per your rule.
  • The symbol is mostly aligned by pin names/numbers, but there are several likely mismatches and a lot of missing pin metadata.
  • The footprint exists and appears to target a 100-pin VQFN with exposed pad, which matches the datasheet package family, but I could only do a structural cross-check from the available layout data.
Metadata review Current project metadata
  • MPN: USB5807C/KD
  • Manufacturer: Microchip
  • Part Type: Integrated Circuits
  • Designator Prefix: IC
  • Datasheet URL: Mouser-hosted PDF
Datasheet-derived metadata
The datasheet identifies USB5807C/KD as a Microchip Technology Inc. low-power, OEM-configurable 7-port USB 3.1 Gen 1 hub controller in a 100-pin VQFN, 12 mm x 12 mm package, with VDD12 = 1.08 V to 1.32 V and VDD33 = 3.0 V to 3.6 V. It supports 7 downstream ports and 1 upstream port, BC 1.2 features, FlexConnect, OTP/SPI/SMBus configuration, and an exposed pad tied to ground. The datasheet also lists commercial 0 C to 70 C and industrial -40 C to 85 C grades.

Schematic symbol review What matches
  • The project contains 101 terminal components, which is consistent with a 100-pin package plus an exposed ground pad being modeled as a separate terminal, matching the datasheet guidance that the exposed pad must be tied to ground.
  • Many core pins align correctly by name and pin number, for example:
Issues found 1. All terminal pin types are still unset
Every terminal I inspected has Pin Type: Unspecified, including power, ground, clock, control, and USB pins. That weakens ERC behavior and is a clear incompleteness issue for an IC-style part project. The sync workflow specifically expects exact pin typing from the datasheet.
2. At least one definite naming mismatch
That is a likely symbol mismatch on pin 55 and should be verified against the original pin table page in the PDF.
3. Ground/exposed pad naming inconsistency
  • The project models the exposed pad as VSS with pin 101
  • The datasheet text refers to the exposed pad / ground as GND, and the extracted pin table does not provide a separate numeric pin for the pad
So this is not necessarily wrong, but it is a naming/numbering ambiguity:
  • electrically: likely fine
  • library accuracy: should be confirmed whether you want the pad terminal named GND or VSS, and whether 101 is your intended internal convention
4. Missing pin descriptions
The terminals do not appear to carry short per-pin descriptions beyond the designator text, even though the datasheet provides meaningful functional descriptions for pins like VBUS_DET/GPIO16, RESET_N, TESTEN, and the PRT_CTL1/GPIO17 through PRT_CTL7/GPIO23 multifunction pins.
5. Missing symbol organization metadata
I did not see populated Section, Pin Group, Pin Orientation, or sub-symbol grouping on the terminals. For a 100-pin hub IC, that is a major completeness gap.
Footprint review What matches
The datasheet describes a 100-pin VQFN, 12.00 mm x 12.00 mm, 0.40 mm pitch package with an optional/exposed center pad about 8.1 mm and a required ground via array. The project layout contains:
  • a footprint object
  • pad objects for all terminals
  • a separate layout footprint container and shape objects
That is structurally consistent with a VQFN package.
What I could not fully verify
The layout tool did not expose pad geometry dimensions, so I could not directly verify:
  • pad width/length against the datasheet land pattern
  • exact 0.40 mm pitch
  • exact body outline size
  • exact center pad size / thermal via pattern
  • pin 1 indicator geometry
Footprint-specific flags
  • The datasheet calls for the exposed pad to connect to ground with a via array, and recommends filled/tented thermal vias for reflow robustness.
  • I could not confirm the center pad geometry or via pattern from the available layout data.
  • I also could not confirm pin-1 marker placement from the footprint object alone, only that the datasheet requires a visible pin-1 indicator.

Bottom line
Your part project is close on raw pin population, but not yet library-clean:
  • pin count is likely correct
  • many pin names/numbers appear correct
  • pin typing and descriptive metadata are incomplete
  • there is at least one likely symbol naming mismatch
  • the footprint is plausibly correct in package family, but I could not dimensionally verify it from the available layout data
If you want, I can next do a full cleanup pass:
  • normalize project properties
  • verify every terminal against the datasheet
  • assign pin types/descriptions/sections/groups
  • flag or correct the mismatched terminal names
  • and produce a concise final mismatch table.
