Part Audit and Datasheet Verification

flux

I reviewed the SAM2695 part project, confirmed the official Dream datasheet URL, and set the Datasheet URL property to:
For this kind of audit, the datasheet should be treated as the source of truth, and the exposed pad must be counted as a pin too . Also, project properties should use the exact system property names to avoid duplicates .

What matches
  • The project has 49 terminal components, which is correct for this device because the datasheet describes a 48-lead QFN/MQFN plus an exposed die pad.
  • The visible footprint metadata also lines up well with the datasheet:
    • datasheet: 6 mm x 6 mm QFN/MQFN
    • project footprint: QFN40P600X600X90-49N
  • The pin numbering and names appear consistent with the datasheet pinout across the part, including AOUTL, AOUTR, MICIN, MIDI_IN, D0-D7, OUTVC12, IRQ, X1, X2, XDIV, and the exposed pad.
Mismatches / issues found

Table

IssueStatus
AGND pin typeMismatch - currently Power In, should be Ground
EXP exposed pad typeMismatch - currently Passive, should be Ground
Digital ground terminalsMismatch - currently set as Power In, should be Ground
Active-low naming styleMinor difference: project uses ~CS, ~RD, ~WR; datasheet uses CS/, RD/, WR/
Pin Description propertyMissing on all pins
Section propertyMissing on all pins
Pin Group propertyMissing on all pins
Pin Orientation propertyMissing on all pins
Sub-symbol Designator SuffixMissing on all pins
Notes
  • The active-low label style difference is mostly cosmetic, not a pin-map error.
  • The biggest real correctness issue is ground classification:
    • AGND
    • all digital ground terminals
    • EXP
  • The exposed pad specifically should be treated as ground because the datasheet describes it as the grounded exposed die pad, and exposed pads count as pins in the audit criteria .
Overall assessment
  • Footprint/package: good
  • Pin count: good
  • Pin names/numbers: good
  • Pin typing: needs correction for ground-related pins
  • Pin metadata completeness: incomplete
If you want, I can do the next cleanup pass and:
  • fix the ground pin types
  • add pin descriptions
  • add Section, Pin Group, Pin Orientation, and sub-symbol grouping for the whole part.
Fix pin metadata
Group by function
Check exposed pad
