## Footprint and pin 1

Pin 1 (E/D) is at the lower left in the top view (as placed on the PCB): pins 1, 2, 3 along the bottom row from left to right, 4, 5, 6 along the top row from right to left (datasheet p.1 pin assignment, PSC-4412 land pattern). The footprint marks it with a silkscreen dot left of pad 1 and a chamfered fab outline.

Land pattern source: PSC-4412 rev 02 'JX6 package outline', sheet 2 'Recommended land pattern dimension' (PDF p.20).

| Dimension | Value (mm) |
|---|---|
| corner pad | 1.30 x 1.00 at x=+-1.30 |
| centre pad | 0.70 x 1.00 at x=0 |
| pad gap x | 0.3 |
| row gap y | 0.9 |
| row centre y | +-0.95 |
| pin1 | bottom-left (top view as on PCB) |

## 3D models

No manufacturer 3D model was available, so the model is **AI-created**: built by Adom from the datasheet drawing (PSC-4412 rev 02 sheet 1 (PDF p.19)). It is a simplified body (substrate, shield or lid, and the contact pads), Z-up and seated on z = 0, centred on the footprint origin.

Simplifications and assumptions: No Renesas STEP retrieved; simplified model; Castellation notches not modelled.

| File | What it is |
|---|---|
| `xlh335040-000000i.step` / `xlh335040-000000i.glb` | Plain model |
| `xlh335040-000000i-etched.step` / `xlh335040-000000i-etched.glb` | The same model with the MPN as a virtual laser mark (top face, adom-aiflow-etch, gate PASS). This is the board/library model. |
| `xlh335040-000000i-hero.glb` | The page's 3D view: the marked model plus teal dashed pad outlines, silkscreen with pin 1 and signal names (adom-hero 1.4). Not for boards. |

The MPN mark is an identification aid added by Adom, not a claim about the manufacturer's real marking.
