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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Seiko Epson |+| Package | SOP-14-208mil |+| Category | RTC |+| Pins | 14 |++## Ordering variants++- `RX8025T-UCUC`++## CAD (KiCad official)++- Symbol: `RX8025T-UC`+- Footprint: `Package_SO:SOIC-14_3.9x8.7mm_P1.27mm`+- 3D model: SOP-14-208mil (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Seiko Epson datasheet](docs/rx8025t-uc-datasheet.pdf) (1 pp, sha256 `4549e3348da5559a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
