PIC16LF18345 Datasheet Review

A

adrian95

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.

flux

I’ll inspect the part metadata, find and attach the official datasheet if missing, then compare symbol/footprint/pin data against the datasheet and report any mismatches.

flux

I found an existing datasheet URL on the part, so I’m using it for extraction and also checking Microchip’s current official PDF as a reference. I’ve finished the metadata/footprint read and am now comparing every symbol pin and pad against the datasheet.

Completed the part review and created the detailed report: Part Datasheet Review: PIC16LF18345-I/SS.
Key result: MPN, 20-SSOP package, pin count, symbol pin numbering, and primary pin names match the Microchip datasheet. Main flags are metadata quality issues: all pins are Unspecified, pin descriptions are missing, the existing datasheet URL is an uploaded copy rather than Microchip’s current official PDF, and the footprint has only minor land-pattern deviations likely acceptable for assembly.

Part Datasheet Review: PIC16LF18345-I/SS
Date: 2026-07-16
Scope
Reviewed available part information for the published Flux part project PIC16LF18345-I_SS, including metadata, schematic symbol terminals, footprint geometry, and pin descriptions/properties. Cross-check source was the existing Datasheet URL plus Microchip's current official datasheet reference found by web search.
Datasheet Sources
  • Existing project Datasheet URL: https://storage.googleapis.com/graviton-electric-symbols/document_assets/user-uploaded/9a9ddca64e94621e83f1fca42f1543d57c4bb1636f8948ec90817c71640a6ded.pdf
  • Existing PDF identified as Microchip PIC16(L)F18325/18345 datasheet DS40001795E.
  • Official current Microchip PDF found: https://ww1.microchip.com/downloads/en/DeviceDoc/PIC16LF18325-18345-Data-Sheet-40001795F.pdf
Datasheet property action: no property update was performed because the part already had a Datasheet URL set. The existing URL points to an uploaded copy rather than Microchip's current official hosted PDF; updating to the Microchip URL is recommended for traceability.

Symbol Metadata Findings
  • All 20 terminals currently have Pin Type: Unspecified.
  • None of the symbol terminals include a Pin Description property.
  • Terminal names intentionally use mostly primary pin names; not every alternate function is embedded in the visible name. This is acceptable for readability, but the missing descriptions mean analog, PPS, timer, comparator, oscillator, MSSP, EUSART, and ICSP functions are not searchable from the symbol metadata.

Footprint conclusion: no critical footprint mismatch found. The footprint is clearly intended for a 20-pin 0.65 mm pitch 5.30 mm body SSOP. The only geometry differences are small land-pattern deviations: pad length is 1.80 mm vs Microchip Y1 max 1.75 mm, and row spacing appears 7.10 mm vs Microchip C nominal 7.20 mm if directly comparable. These are likely acceptable for normal assembly but should be adjusted if strict Microchip land-pattern conformance is required.
Mismatches / Risks Flagged

Table

SeverityFindingImpactRecommended action
MediumAll terminal Pin Type values are Unspecified.Weak ERC behavior; power/GND and I/O behavior not self-documenting.Set VDD=Power In, VSS=Ground, GPIO pins=Bi-Directional/Programmable, MCLR/VPP/RA3=Input or suitable multifunction type.
MediumPin descriptions are missing for all 20 terminals.Datasheet alternate functions are not searchable or visible in metadata.Add datasheet-derived descriptions for each pin.
LowExisting Datasheet URL is an uploaded PDF copy, while official Microchip DS40001795F URL is available.Traceability/version risk; current URL appears to be DS40001795E.Prefer the official Microchip PDF URL for the Datasheet property if editable.
LowPart Type is Integrated Circuits rather than Microcontroller.BOM/category specificity is reduced.Change to Microcontroller if supported by the library taxonomy.
LowDescription contains duplicated wording: 8bit 8 bit.Cosmetic metadata issue.Clean up description text.
LowFootprint pad length is 1.80 mm vs Microchip land pattern Y1 max 1.75 mm.Very small assembly/clearance difference; likely acceptable.Optionally shorten pads to 1.75 mm for strict datasheet conformance.
LowFootprint row center spacing appears 7.10 mm vs Microchip C nominal 7.20 mm if directly comparable.Small geometry deviation; likely acceptable.Optionally adjust row spacing to match Microchip land pattern after confirming C definition.
Overall Result
  • Identity, package, pin count, pin numbers, and primary pin names match the datasheet.
  • No functional pinout mismatch or package-family mismatch was found.
  • The main issues are metadata completeness and minor land-pattern conformance differences, not electrical pin mapping errors.
