Part Datasheet Review


Updated all 65 terminals so Pin Group and Section are populated and identical using broad functional groups: Power, Ground, Cell Monitor, Communication, GPIO, Current Sense, and Thermal Pad.
Open items:
  • AVSS_2 remains grouped as Thermal Pad because pin 65 is the exposed PowerPAD, not a normal datasheet pin.
Suggested next steps:
  1. Rename AVSS_2 to PowerPAD or EP.
  2. Rebuild the HTQFP-64 PAP footprint.
  3. Run part review checks after the footprint is fixed.
Assign Terminal Order and Pin Orientation, then run a schematic/symbol review.
I’ll assign terminal order and orientation by broad groups using your conventions, then run symbol/part checks and verify the schematic metadata.
Assigned Terminal Order and Pin Orientation for all 65 terminals: Power = order 1/top, Cell Monitor = 2/left, Communication = 3/right, GPIO = 4/right, Current Sense = 5/left, Thermal Pad = 9/bottom, Ground = 10/bottom.
Open items:
  • Schematic/symbol review returned no open warnings/errors for the checked component-review categories.
  • Footprint quality is still a separate unresolved issue from the prior review.
Suggested next steps:
  1. Rebuild the HTQFP-64 PAP0064F footprint.
  2. Run footprint/layout checks after footprint generation.
  3. Publish the part once footprint checks pass.
