**Lucki** · Crystals · SMD3225-4P

L327S320A11L from Lucki, in a SMD3225-4P. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | XTAL1 | passive | Crystal terminal connected to one side of the resonator (32.000 MHz, CL 6 pF), marked with the chamfered pad as pin 1. |
| 2 | GND | power_in | Ground pad, connected to the metal lid/ground per the connection diagram. |
| 3 | XTAL2 | passive | Crystal terminal connected to the other side of the resonator (32.000 MHz, CL 6 pF). |
| 4 | GND | power_in | Ground pad, connected to the metal lid/ground per the connection diagram. |
