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 | INT1 | output | Output pin for interrupt signal 1. Nch open-drain output with no protective diode at VDD. Can be configured (via Status Register 2) as alarm 1 interrupt, user-set frequency output, minute-periodical interrupt 1/2, or 32.768 kHz clock output. Requires an external pull-up resistor. |+| 2 | XOUT | passive | Quartz crystal connection pin. Connect a 32.768 kHz quartz crystal between XIN and XOUT. Load capacitance Cd is built-in; only external Cg may be required. |+| 3 | XIN | passive | Quartz crystal connection pin. Connect a 32.768 kHz quartz crystal between XIN and XOUT. |+| 4 | VSS | power_in | Ground (GND) reference pin. Connect to system ground. |+| 5 | INT2 | output | Output pin for interrupt signal 2. Nch open-drain output with no protective diode at VDD. Configurable (via Status Register 2) as alarm 2 interrupt, user-set frequency output, or minute-periodical interrupt 1. Requires an external pull-up resistor. |+| 6 | SCL | input | Serial clock input pin for the I2C-bus interface. CMOS input with no protective diode at VDD. SDA data is synchronized to this clock. |+| 7 | SDA | bidirectional | Serial data I/O pin of the I2C-bus interface. CMOS input and Nch open-drain output (no protective diode at VDD). Pull up to VDD via a resistor; supports wired-OR with other open-drain/collector devices. |+| 8 | VDD | power_in | Positive power supply pin. Operating range 1.3 V to 5.5 V. Typical quiescent current 0.25 µA at VDD = 3.0 V, Ta = +25 °C. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | ABLIC |+| Package | SOIC-8 |+| Category | RTC |+| Pins | 8 |++## Ordering variants++- `S-35390A-J8T1U`+- `S-35390A-J8T1UJ8T1G`+- `S-35390A-J8T1UT8T1U`+- `S-35390A-J8T1UT8T1G`+- `S-35390A-J8T1UI8T1U`++## CAD (KiCad official)++- Symbol: `S-35390A-J8T1U`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [ABLIC datasheet](docs/s-35390a-j8t1u-datasheet.pdf) (57 pp, sha256 `4a8654978deb6f09`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
