Cross-Check: Symbol and Footprint vs Datasheet

Check itemResultRisk
Pin countPass - project has 32 leads + exposed padLow
Pin numberingPass - schematic numbering matches datasheet Table 5Low
NC pinsPass - NC_1 and NC_2 are correctly presentLow
RESET namingPass - ~RESET matches active-low RESET functionLow
Exposed pad presencePass - EP exists as pad 33Low
Exposed pad electrical requirementWarning - datasheet says exposed pad is soldered to VSS and recommends soldering to VSS for thermal/crosstalk reasons; project currently has no nets definedHigh if left unconnected in a real design
Footprint package familyPass with note - footprint asset name is QFN50P500X500X80-33N-D, while datasheet calls package LFCSP_WQ CP-32-7; dimensions and 33-pad structure alignMedium metadata ambiguity only
Footprint pitchPass - 0.50 mm matches datasheetLow
Exposed pad sizePass - footprint center pad 3.25 mm x 3.25 mm matches datasheet max exposed pad sizeLow
Pad count/orientationPass - 8 pads per side plus EP matches packageLow
Pull-up requirements on serial pinsWarning - datasheet requires external pull-ups on SDA and SCL; none exist in this part-only projectNot a part-library failure, but important for end-use design

Issues Most Likely to Matter

PriorityFindingWhy it matters
1EP must be tied to VSS in downstream designsCould cause electrical/thermal/crosstalk problems if omitted
2Package metadata is generic LFCSP, while datasheet-specific package is CP-32-7 / LFCSP_WQCould increase part-ordering or footprint-selection confusion
3No nets are defined in the part projectPrevents validating electrical intent beyond pin mapping

Bottom Line

VerdictSummary
Symbol pinoutGood
Footprint geometryLooks consistent with datasheet
Manufacturing-blocking mismatch foundNone obvious
Important cautionEnsure EP is connected to VSS in actual use, and keep package naming specific to CP-32-7
If you want, I can next turn this into a concise part QA checklist or a cleaned-up pin/property table for the part definition.
