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 to one terminal of the 32.768-kHz crystal (nominal CL = 12 pF; Rs max 70 kΩ). |+| 2 | OSCO | output | Oscillator output. Connect to the other terminal of the 32.768-kHz crystal. |+| 3 | VBACK | power_in | Backup device power. Connects to a supercapacitor or non-rechargeable battery (operating range 1.4 V to VCC; switchover at 2.0 V typical). Integrated trickle charger sources current to this pin. |+| 4 | GND | power_in | Ground reference for the device. |+| 5 | SDA | bidirectional | I2C serial data line. Open-drain; requires external pull-up to VCC (typical 4.7 kΩ). Supports Standard (100 kHz) and Fast (400 kHz) modes. |+| 6 | SCL | input | I2C serial interface clock input, up to 400 kHz. Requires external pull-up to VCC (typical 4.7 kΩ). |+| 7 | IRQ | output | Configurable interrupt output; open-drain, active-low. Programmable via FT/FTF/OUT bits as static output, 1 Hz, or 512 Hz. Requires external pull-up to VCC (typical 4.7 kΩ). Unused during backup-supply operation. |+| 8 | VCC | power_in | Main device supply, 3.0 V to 3.6 V (absolute max 4 V). Place 1 µF decoupling capacitor close to this pin. Typical ICC = 100 µA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOP-8 |+| Category | RTC |+| Pins | 8 |++## Ordering variants++- `BQ32000DR`++## CAD (KiCad official)++- Symbol: `BQ32000DR`+- 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:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/bq32000.pdf) (34 pp, sha256 `245c32e30aa919eb`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
