SX3M32.768KB10F20TLN from Shenzhen SCTF Elec, 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 | Tri-State | input | Output enable (tri-state) input: output is disabled if OE is Logic 0 (VIL max 0.3Vdd) and enabled if OE is Logic 1 (VIH min 0.7Vdd) or left open. |
| 2 | GND | power_in | Ground connection. |
| 3 | Output | output | CMOS 32.768 kHz clock output, rated for a 15 pF load with VOH min 0.9Vdd and VOL max 0.1Vdd. |
| 4 | Vdd | power_in | Positive supply voltage, 1.8 V min to 3.3 V max. |
