ECS-327MVATX-2-CN-TR3 from ECS INTERNATIONAL INC, 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: VIH ≥ 0.7Vdd or NC (internal pullup) gives oscillation, VIL ≤ 0.3Vdd gives high impedance output. |
| 2 | Gnd | power_in | Ground connection. |
| 3 | Output | tri_state | CMOS clock output at 32.768 kHz, 15 pF load, VOH 0.9 Vdd min, VOL 0.1 Vdd max, high impedance when tri-state pin is low. |
| 4 | Vdd | power_in | Supply voltage pin, 1.6 V to 3.6 V. |
