Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.
I’ll audit the part metadata, find and attach the official Microchip datasheet if needed, then cross-check the symbol, footprint, and pin descriptions and document any mismatches.
The part is a Microchip PIC16F18446 in the extended-temperature, 20-lead PDIP ordering variant. The official datasheet is PIC16(L)F18426/46 Data Sheet DS40001985C.
Current metadataOrdering-code interpretation
PIC16F18446: 8-bit PIC microcontroller, 28 KB Flash family member.
E: extended temperature range, -40°C to +125°C.
/P: 20-lead, 300 mil body PDIP package.
Key specifications
Architecture: enhanced mid-range 8-bit PIC MCU.
Maximum clock: 32 MHz.
Operating voltage for PIC16F variant: 2.3 V to 5.5 V.
Audit complete. I attached and verified the official Microchip datasheet; the 20-pin PDIP footprint and pin-number mapping match, but pin 4’s electrical type, VSS typing, canonical MPN formatting, broad part type, and missing pin descriptions need correction.
