SX2B32.000F1210F30 from Shenzhen SCTF Elec, in a SMD2520-4P. 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 1 (pin-1 pad with chamfered corner), one side of the 32.000MHz resonator with 12pF load capacitance. |
| 2 | NC/COVER | passive | Connected to the metal cover; the datasheet says to connect it to GND or leave it floating. |
| 3 | XTAL2 | passive | Crystal terminal 2, the other side of the 32.000MHz resonator with 12pF load capacitance. |
| 4 | NC/COVER | passive | Connected to the metal cover; the datasheet says to connect it to GND or leave it floating. |
