RX8025T-UC

Seiko Epson · Real-time Clocks (RTC) · SOP-14-208mil

RX8025T-UC from Seiko Epson, in a SOP-14-208mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 T1(CE) input Manufacturer test pin. Do not connect externally.
2 SCL input I2C-Bus serial clock input. Interface speed up to 400 kHz. Requires external pull-up to VDD (1.8-5.5 V).
3 FOUT output Reference clock output (CMOS output, CL = 30 pF). Selectable 32.768 kHz, 1024 Hz, or 1 Hz. Enabled via the FOE pin.
4 N.C. unconnected No internal connection. Leave open or tie to GND per board practice.
5 TEST input Manufacturer test pin. Do not connect externally.
6 VDD power_in Positive supply input. Wide timekeeper range 1.6-5.5 V; interface 1.8-5.5 V; temperature-compensated range 2.2-5.5 V. Decouple locally.
7 FOE input FOUT output enable control input. Drive high to enable FOUT, low to disable.
8 N.C. unconnected No internal connection.
9 N.C. unconnected No internal connection.
10 /INT output Interrupt output, N-channel open drain. Asserted low by alarm or timer events. Requires external pull-up resistor to VDD.
11 GND power_in Ground reference (0 V).
12 T2(VPP) input Manufacturer test pin (VPP). Do not connect externally.
13 SDA bidirectional I2C-Bus serial data input/output (open-drain). Requires external pull-up to VDD.
14 N.C. unconnected No internal connection.

Ordering variants

Same part, different packaging or reel option.

  • RX8025T-UC

CAD (KiCad official)

  • Symbol: RX8025T-UC
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOP-14-208mil (KiCad packages3D, STEP)
  • 3D model files: rx8025t-uc-etched.step / rx8025t-uc-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rx8025t-uc.step / rx8025t-uc.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
rx8025t-uc.step 195 KB You want the bare part, or you mark your own boards.
rx8025t-uc-etched.step 2.5 MB You want the part with RX8025T-UC already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 618 faces against 237 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
