ASDK2-32.768KHZ-LR-T3 from Abracon LLC, 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 | Tri-state | input | Tri-state control: open or VIH ≥ 0.7Vdd gives oscillation, VIL < 0.3Vdd puts the output in Hi-Z (disable current 10 µA max). |
| 2 | GND | power_in | Ground; a bypass capacitor of approximately 0.01 µF is recommended between pin 2 and pin 4. |
| 3 | Output | output | 32.768 kHz CMOS output rated for up to 15 pF load, with VOH min 0.9Vdd and VOL max 0.1Vdd. |
| 4 | Vdd | power_in | Supply voltage: 3.3 V standard (2.97 to 3.66 V), 2.5 V option 1 (2.375 to 2.625 V), or 1.8 V option 2 (1.71 to 1.89 V), with approximately 0.01 µF bypass to pin 2 recommended. |
