Q22FA12800393 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 | #1 | passive | Crystal unit terminal of the FA-128; the datasheet gives no individual function for this pin, and the unit's drive level is limited to 100 µW max (200 µW max). |
| 2 | #2 | power_in | Internally connected to the metal cover; the datasheet instructs the customer to connect it to ground. |
| 3 | #3 | passive | Crystal unit terminal of the FA-128; the datasheet gives no individual function for this pin, and the unit's drive level is limited to 100 µW max (200 µW max). |
| 4 | #4 | power_in | Internally connected to the metal cover; the datasheet instructs the customer to connect it to ground. |
