Key findings: the symbol pin numbers/functions match the datasheet, and the 21 terminals are correct for 20 leads + EP. Issues flagged: package metadata/description incorrectly mention SSOP, part classification looks wrong, pin types/descriptions are missing, and the footprint perimeter pads do not match Microchip’s recommended land pattern.
Please fix this, based from this flag issue:
MCP9601-E/MX library metadata reports packagecasecode as 20-SSOP and description also says 20-lead SSOP, but Microchip datasheet says MX is 20-lead MQFN/VQFN 5x5x1.0mm.
Description: Removed the incorrect SSOP reference and updated it to 20-lead MQFN/VQFN, 5 × 5 × 1.0 mm, 0.65 mm pitch, exposed pad, per the Microchip datasheet.
