# STM32G431CBT6: drawn model against the datasheet

Model: KiCad's official 3D library, `LQFP-48_7x7mm_P0.5mm.step` (KiCad 10.0.5 `3dmodels`, made by the kicad-packages3D generator), licensed CC BY-SA 4.0 with KiCad's design exception. It is not the manufacturer's model: no manufacturer STEP can be redistributed (see ../provenance.json).
Datasheet: ST DS12589 Rev 6, p.171 Table 92 (LQFP48). Measured with the shared step2glb service's /step-meta (every face's bounding box).

| Dimension | Datasheet min | Datasheet max | Model | Result |
|---|---|---|---|---|
| Overall span | 8.8 | 9.2 | 9.0 | pass |
| Body length (along the rows) | 6.8 | 7.2 | None | not measured |
| Overall height | - | 1.6 | 1.5 | pass |
| Standoff | 0.05 | 0.15 | 0.1 | pass |
| Lead pitch | 0.5 | 0.5 | 0.5 | pass |
| Leads | 48 | 48 | 48 | pass |

Body top face (drafted, so smaller than the body at its parting line): 6.584 x 6.584 mm. The body width across the rows is shown in the overlay against the datasheet's min and max boxes.
