TSX-3225 16.0000MF18X-AC3

Seiko Epson · Pre-ordered Products · SMD3225-4P

TSX-3225 16.0000MF18X-AC3 from Seiko Epson, 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 XTAL1 passive Crystal terminal connected to one side of the resonator in the internal connection diagram (16.0 MHz fundamental, 3.2 x 2.5 mm package).
2 GND (cover) power_in Connected to the cover internally; the datasheet says to connect it to ground.
3 XTAL2 passive Crystal terminal connected to the other side of the resonator in the internal connection diagram.
4 GND (cover) power_in Connected to the cover internally; the datasheet says to connect it to ground.
