ECS-327MVATX-3-CN-TR

ECS · Pre-ordered Products · SMD3225-4P

ECS-327MVATX-3-CN-TR from ECS, 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 Tri-state input Tri-state control: VIH ≥ 0.7Vdd gives oscillation, VIL ≤ 0.3Vdd gives high impedance output.
2 Gnd power_in Ground connection.
3 Output output CMOS 32.768 kHz clock output driving up to 15 pF load, VOH min 0.9 Vdd and VOL max 0.1 Vdd.
4 Vdd power_in Supply voltage pin, 1.6 V to 3.6 V.
