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 | Oscillator input. Connect the 32.768 kHz quartz crystal between OSCI and OSCO. Internal load capacitance is provided (CINT typ 25 pF). |+| 2 | OSCO | output | Oscillator output. Second terminal of the 32.768 kHz crystal network. |+| 3 | /INT | output | Interrupt output, open-drain, active low. Asserted by the alarm/timer sources; requires an external pull-up to VDD. |+| 4 | VSS | power_in | Ground / negative supply reference (0 V). |+| 5 | SDA | bidirectional | I2C serial data I/O, open-drain. Requires external pull-up to VDD. Bus supports up to 400 kbit/s (fast-mode). Slave addresses: 0A3H (read) / 0A2H (write). |+| 6 | SCL | input | I2C serial clock input. Requires external pull-up to VDD. fSCL up to 400 kHz. |+| 7 | CLKOUT | output | Programmable clock output, open-drain. Selectable frequency of 32.768 kHz, 1024 Hz, 32 Hz or 1 Hz; requires an external pull-up to VDD. |+| 8 | VDD | power_in | Positive supply voltage, 2.5 V to 5.5 V. Absolute maximum +6.5 V. Typical IDD ~0.25 uA at VDD=3.0 V, TA=25 degC with CLKOUT disabled. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HXY MOSFET |+| Package | SOP-8 |+| Category | RTC |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `PCF8563T-HXYT`++## CAD (KiCad official)++- Symbol: `PCF8563T-HXY`+- 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:** [HXY MOSFET datasheet](docs/pcf8563t-hxy-datasheet.pdf) (18 pp, sha256 `9082c93f2bab6991`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
