YSN8010SJ 32.768KHZ from YXC Crystal Oscillators, in a SOP-8. 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 | unconnected | Manufacturer test pin only; the datasheet requires it to be left floating. |
| 2 | T2 | unconnected | Manufacturer test pin only; the datasheet requires it to be left floating. |
| 3 | FOUT | output | Configurable CMOS frequency output, selected by FSEL[1:0] as 32768 Hz (default), 1024 Hz or 1 Hz and enabled by FOE[1:0] (FOUT disabled by default); VOH is 2.2 V min at VDD=3.0 V, IOH=-1 mA, and VOL is GND+0.8 V max at VDD=3.0 V, IOL=1 mA. |
| 4 | GND | power_in | Ground reference, with test conditions specified at GND = 0 V. |
| 5 | SDA | bidirectional | I2C serial data line; output low is GND+0.4 V max at VDD≥3.0 V and IOL=3 mA, and the input voltage must not exceed 6.5 V. |
| 6 | SCL | input | I2C serial clock input with VIH min 0.8×VDD and VIL max 0.2×VDD, and an input voltage limit of 6.5 V. |
| 7 | T3 | unconnected | Manufacturer test pin only; the datasheet requires it to be left floating. |
| 8 | VDD | power_in | Supply voltage of 1.6 V to 5.5 V for timekeeping (2.5 V to 5.5 V in normal mode), and at least 2.5 V must be applied during power-on and oscillator start-up; absolute maximum is 6.5 V. |
