SX3M32.768KM20F30TNN 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 | OE | input | Tri-state output enable: output is enabled at logic 1 (VIH min 0.7Vdd) or when left open, and disabled at logic 0 (VIL max 0.3Vdd). |
| 2 | GND | power_in | Ground connection for the oscillator supply and output return. |
| 3 | OUT | output | 32.768kHz CMOS clock output rated for a 15pF load, with VOH min 0.9Vdd and VOL max 0.1Vdd. |
| 4 | VDD | power_in | Supply voltage input, 1.62V to 3.63V, with a 0.01µF bypass capacitor shown in the test circuit. |
