## CAD (KiCad official)
- Symbol: `M2354SJFAE`
- Footprint: `Package_QFP:LQFP-64_7x7mm_P0.4mm`
- 3D model: LQFP-64(7x7) (KiCad packages3D, STEP)
- 3D model files: `m2354sjfae-etched.step` / `m2354sjfae-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `m2354sjfae.step` / `m2354sjfae.glb` are the bare package body.
