Completed the part review and updated the Datasheet URL to Microchip’s official DS20006027B PDF. I created the full findings in Part Information Review: MCP2518FDT-E/QBB.
Open items:
  • Pinout and package identity match the datasheet.
  • Issues flagged: all symbol pin types are Unspecified, pin descriptions are missing, NCS should indicate active-low, side pads are 0.85 mm vs 0.80 mm recommended, and EP/VSS/paste/thermal-via guidance should be documented.
Suggested next steps:
  1. Update pin types and pin descriptions from the datasheet.
  2. Rename NCS to an active-low form like ~CS or nCS.
  3. Decide whether to adjust side pad length to exactly match Microchip’s land pattern.

Update the pin types, add pin descriptions, rename NCS active-low, and adjust the side pads to 0.80 mm.

I’ll update the symbol terminal metadata, rename the chip-select pin to active-low notation, adjust the QBB side-pad land length to 0.80 mm, then re-inspect the part.

flux

Symbol metadata and active-low naming are updated; the 14 side pads have been resized to 0.80 mm. I’m verifying the final schematic and footprint now.

flux

Completed the requested cleanup: pin types/descriptions are set, NCS is now ~CS, and all 14 side pads are now 0.80 mm long while EP remains unchanged.
Open items:
  • EP still needs board-level VSS connection guidance when used in a design.
  • Thermal vias and segmented EP paste are still assembler/application dependent.
I also updated Part Information Review: MCP2518FDT-E/QBB with the applied changes.
