XRCGB27M120F3M00R0 from Murata Electronics, 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 | XTAL1 | passive | Crystal terminal, one side of the 27.12 MHz resonator (6pF load capacitance, 150uW drive level). |
| 2 | NC | unconnected | No connection, as stated in the package drawing legend. |
| 3 | XTAL2 | passive | Crystal terminal, the other side of the 27.12 MHz resonator (6pF load capacitance, 150uW drive level). |
| 4 | NC | unconnected | Fourth pad is drawn on the package but not labeled in the legend; assumed no connection. |
