Ordering variants

Same part, different packaging or reel option.

  • C8051F310-GQRGM

CAD (KiCad official)

  • Symbol: C8051F310-GQR
  • Footprint: Package_QFP:LQFP-32_7x7mm_P0.8mm
  • 3D model: LQFP-32(7x7) (KiCad packages3D, STEP)
  • 3D model files: c8051f310-gqr-etched.step / c8051f310-gqr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); c8051f310-gqr.step / c8051f310-gqr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
c8051f310-gqr.step 413 KB You want the bare part, or you mark your own boards.
c8051f310-gqr-etched.step 4.1 MB You want the part with C8051F310-GQR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 996 faces against 507 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
