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 one terminal of the 32.768 kHz quartz crystal here; a series trimmer capacitance Ctrim (5-25 pF) is applied on this pin to tune the load capacitance (CL parallel = 7-12.5 pF target). |+| 2 | OSCO | output | Oscillator output. Connect the second terminal of the 32.768 kHz quartz crystal here. Internal capacitance on OSCO is 15-35 pF (typ 25 pF). |+| 3 | INT | output | Interrupt output, open-drain, active LOW. Asserted by the alarm and/or timer flags (AF/TF) subject to AIE/TIE enables. Requires an external pull-up to VDD; IOL >= 1 mA at VOL = 0.4 V. |+| 4 | VSS | power_in | Ground reference (0 V). |+| 5 | SDA | bidirectional | I2C-bus serial data input/output. Open-drain; requires external pull-up. Slave address: read A3h / write A2h. Supports standard and fast modes up to 400 kHz (VDD >= 1.8 V). IOL(SDA) >= 3 mA at VOL = 0.4 V. |+| 6 | SCL | input | I2C-bus serial clock input. Requires external pull-up. Supports up to 400 kHz. Input thresholds: VIL <= 0.3 VDD, VIH >= 0.7 VDD. |+| 7 | CLKOUT | output | Programmable clock output, open-drain. Software-selectable frequencies of 32.768 kHz (default), 1.024 kHz, 32 Hz, and 1 Hz via CLKOUT_control (address 0Dh). Requires external pull-up; goes high-impedance when disabled. IOL >= 1 mA at VOL = 0.4 V. |+| 8 | VDD | power_in | Supply voltage. 1.2-5.5 V with interface inactive; 1.8-5.5 V for full 400 kHz I2C operation. Absolute max +6.5 V. Typical IDD ~ 500 nA at VDD = 3.0 V (interface inactive, CLKOUT disabled). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | GATEMODE |+| Package | MSOP-8 |+| Category | RTC |+| Pins | 8 |++## Ordering variants++- `BM8563EMAEMA`+- `BM8563EMAESA`+- `BM8563EMAEHA`+- `BM8563EMAENA`++## CAD (KiCad official)++- Symbol: `BM8563EMA`+- Footprint: `Package_SO:MSOP-8_3x3mm_P0.65mm`+- 3D model: MSOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [GATEMODE datasheet](docs/bm8563ema-datasheet.pdf) (29 pp, sha256 `636c5bb2af64a7e3`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
