## CAD (KiCad official)

- Symbol: `R7FA2A1AB3CFM#AA0`
- Footprint: `Package_QFP:LQFP-64_10x10mm_P0.5mm`
- 3D model: LQFP-64(10x10) (KiCad packages3D, STEP)
- 3D model files: `r7fa2a1ab3cfm-aa0-etched.step` / `r7fa2a1ab3cfm-aa0-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `r7fa2a1ab3cfm-aa0.step` / `r7fa2a1ab3cfm-aa0.glb` are the bare package body.
