27 Oct 2026Claude, at Caleb Taylor's requestValidated against TI's TUSB321 datasheet (SLLSEO6C, revised August 2018)files match
SymbolFootprint3D modelPinsfor all variants
  • ✓Datasheet: the page already carries TI's current edition (SLLSEO6C, June 2015, revised August 2018; sha256 ef1cea96d1e85a98 matches ti.com/lit/ds/symlink/tusb321.pdf fetched 2026-10-27); edition now recorded
  • ✓All 12 pins match the Pin Functions table and the RWB 12-pin X2QFN top view (p.3) by number and name: CC1, CC2, CURRENT_MODE, PORT, VBUS_DET, VCONN_FAULT (printed with an overbar in both the drawing and the table, kept as ~{VCONN_FAULT}), OUT1, OUT2, ID, GND, DIR, VDD; no renames needed
  • ✓Pin types agree with the table: CC1/CC2 I/O -> bidirectional, CURRENT_MODE/PORT/VBUS_DET I -> input, VCONN_FAULT/ID/DIR O (open drain) -> open_collector, GND G and VDD P -> power_in
  • •OUT1 and OUT2 are typed I/O in the table but described there as open-drain outputs for the UFP current-mode result; kept open_collector
  • ✓All 12 descriptions rewritten to the table wording (p.3); the earlier text added values not in the pin table (5.1 kΩ, 887 kΩ, 95 kΩ, 200 mA, 7-13 µs, VOL, VCONN FET RON, 4.5-5.5 V)
  • ✓Footprint vs RWB0012A (p.22-23): 12 pads, e = 0.40 mm, in the same orientation as TI's land pattern example: pins 1/2 on the left (1 upper), 3-6 along the bottom, 7/8 on the right (8 upper), 9-12 along the top (12 top-left). Pads 1/2/7/8 0.85 x 0.20 at x = ±0.725, y = ±0.20 (TI 0.7 x 0.2 at ±0.65, 2X 0.4); pads 3-6/9-12 0.20 x 0.65 at y = ±0.825 (TI 0.2 x 0.5 at ±0.75); same inner edges as TI's land, 0.15 longer outward; pad width 0.20 against b 0.15-0.25; no exposed pad
  • •The p.3 pinout figure is drawn rotated 90 degrees from the package drawing and land pattern (pins 1/2 on the top edge there); both are top views numbered counterclockwise, so the numbering agrees
  • ✓3D body 1.60 x 1.60 x 0.40 mm against 1.55-1.65 x 1.55-1.65, 0.4 max (p.22); seated on z = 0, centred on the pads; in the matching GLB the pin-1 dot is at the top-left corner and the two-terminal sides are left/right, the same orientation as the footprint (the square body cannot show a 90-degree error in a bounding box)
  • ✓DigiKey 296-42400-2-ND (tape and reel; DigiKey product URL names TUSB321RWBR) and Mouser 595-TUSB321RWBR kept and added to specs
  • ✓Symbol and footprint Datasheet properties point at the manufacturer datasheet URL
  • ✓Symbol Datasheet / MPN / Manufacturer / DigiKey / Mouser / LCSC properties agree with page.json; footprint Datasheet property points at the manufacturer datasheet URL
  • ✓component-page-verify: all checks pass

SymbolFootprint3D modelPinsfor all variants
  • ✓Footprint extracted pad-for-pad from the source board and normalized to the footprint frame (back-side parts un-mirrored)
  • ✓3D model seated z=0 at footprint origin (placement inverse; method centroid-matched to KiCad library models on 59 cases)
  • ✓adom-lbr generate + lint passed
  • ✓12 of 12 pins described from the datasheet (adom-ds2sf, page-cited)
  • •Not yet checked by a person: land pattern vs datasheet, pin-1/orientation, 3D body vs drawing
