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 | OSCI | input | 32.768 kHz crystal oscillator input. Connect to one terminal of a 32.768 kHz quartz crystal; internal oscillator capacitors are integrated but an external trim cap (5-25 pF) may be used for frequency adjustment. Absolute-max input voltage -0.5 V to VDD+0.5 V. |+| 2 | OSCO | output | 32.768 kHz crystal oscillator output. Connect to the other terminal of the 32.768 kHz quartz crystal. Do not load externally beyond the crystal network. |+| 3 | /INT | output | Interrupt output, active LOW, open-drain. Asserted by the alarm flag (AF) and/or timer flag (TF) per the AIE/TIE and TI/TP settings in control/status register 2. Requires an external pull-up resistor to V1/VDD; leave floating or tie to VDD via pull-up if unused. |+| 4 | VSS | power_in | Ground / negative supply reference (0 V). |+| 5 | SDA | bidirectional | I2C serial data I/O (open-drain). Requires an external pull-up resistor (R = tr/Cb) to V1/VDD. Supports up to 400 kHz bus rate over VDD = 1.8-5.5 V; VIL ≤ 0.3·VDD, VIH ≥ 0.7·VDD. |+| 6 | SCL | input | I2C serial clock input (open-drain, requires external pull-up to V1/VDD). Max clock frequency 400 kHz; VIL ≤ 0.3·VDD, VIH ≥ 0.7·VDD. In EXT_CLK test mode the SCL role is separate from CLKOUT which becomes the test-clock input. |+| 7 | CLKOUT | output | Programmable clock output (open-drain). Selectable frequency 32.768 kHz (default), 1024 Hz, 32 Hz, or 1 Hz via the CLKOUT frequency register (0Dh). High-impedance when FE=0. In EXT_CLK test mode (TEST1=1) this pin becomes an input for an external 64 Hz test clock. |+| 8 | VDD | power_in | Positive supply. Operating range 1.8 V to 5.5 V for I2C-active operation (down to ~1.0 V for data retention with I2C inactive). Absolute max 6.5 V. Typical sleep current 0.25 uA at VDD=3.0 V, Tamb=25°C. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Wuxi I core Elec AIP8563SA8 TR |+| Package | SOP-8 |+| Category | RTC |+| Pins | 8 |++## Ordering variants++- `AIP8563SA8.TR`+- `AIP8563SA8.TRSA8.TB`+- `AIP8563SA8.TRDA8.TB`+- `AIP8563SA8.TRTA8.TR`+- `AIP8563SA8.TRMA8.TR`+- `AIP8563SA8.TRMA8.TB`++## CAD (KiCad official)++- Symbol: `AIP8563SA8.TR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Wuxi I core Elec AIP8563SA8 TR datasheet](docs/aip8563sa8-tr-datasheet.pdf) (None pp, sha256 `0f0c54d944398d78`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
