YSN8025TS 32.768KHZ from YXC Crystal Oscillators, in a SOP-14. 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 | T1 | input | Factory test pin, not to be externally connected in application. |
| 2 | SCL | input | I2C bus serial clock input; logic high requires at least 0.7*VDD and the input must stay within 5.5 V max. |
| 3 | FOUT | output | CMOS 32.768 kHz clock output that is enabled when FOE is high and goes high-impedance (H-Z) when output is stopped. |
| 4 | NC | unconnected | Not connected to any internal IC circuit. |
| 5 | TEST | input | Factory test pin, no external connection required. |
| 6 | VDD | power_in | Positive power supply; interface operating voltage 2.0 V to 5.5 V, timekeeping hold voltage 1.8 V to 5.5 V, with a bypass capacitor of at least 0.1 uF required between VDD and GND. |
| 7 | FOE | input | Controls FOUT output mode: high enables the 32.768 kHz output; logic high requires at least 0.7*VDD and the pin may be left floating or grounded if FOUT is not used. |
| 8 | NC | unconnected | Not connected to any internal IC circuit. |
| 9 | NC | unconnected | Not connected to any internal IC circuit. |
| 10 | INT | output | Open-drain interrupt output for alarm, periodic timer and time-update signals; it is pulled low when active and requires an external pull-up resistor. |
| 11 | GND | power_in | Power supply ground. |
| 12 | T2 | passive | Factory test pin; may be left floating or connected to VDD in application. |
| 13 | SDA | bidirectional | I2C bus data line; N-channel open-drain output that must be connected to a pull-up resistor, with logic high at least 0.7*VDD and maximum 5.5 V. |
| 14 | NC | unconnected | Not connected to any internal IC circuit. |
