## CAD (KiCad official)
- Symbol: `FU6572N`
- Footprint: `Package_DFN_QFN:QFN-40-1EP_5x5mm_P0.4mm_EP3.6x3.6mm`
- 3D model: QFN-40-EP(5x5) (KiCad packages3D, STEP)
- 3D model files: `fu6572n-etched.step` / `fu6572n-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `fu6572n.step` / `fu6572n.glb` are the bare package body.
