Q22FA12800018 from Seiko Epson, in a SMD2016-4P. 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 | X'tal | passive | One crystal terminal of the FA-128 resonator, to be connected across pin 3 with the external circuit; the datasheet states no separate voltage or current limit for this pin. |
| 2 | GND | power_in | Ground terminal that is internally connected to the cover, and the datasheet asks that it be connected to ground. |
| 3 | X'tal | passive | Second crystal terminal of the FA-128 resonator, paired with pin 1; the datasheet states no separate voltage or current limit for this pin. |
| 4 | GND | power_in | Ground terminal that is internally connected to the cover, and the datasheet asks that it be connected to ground. |
