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 | A0 | input | Device address input bit 0. Hard-wired to VCC or GND to set one of eight possible I2C device addresses (upper nibble 1010, followed by A2/A1/A0). Internally biased low if left floating. |+| 2 | A1 | input | Device address input bit 1. Hard-wired to VCC or GND to help form the 7-bit I2C slave address. Internally biased low if left floating. |+| 3 | A2 | input | Device address input bit 2. Hard-wired to VCC or GND to help form the 7-bit I2C slave address. Internally biased low if left floating. |+| 4 | GND | power_in | Ground reference for supply and I/O signals. |+| 5 | SDA | bidirectional | I2C serial data line. Open-drain bidirectional; requires an external pull-up resistor to VCC. May be wire-ORed with other open-drain/open-collector devices on the same bus. |+| 6 | SCL | input | I2C serial clock input. Data is latched into the EEPROM on the positive edge and clocked out on the negative edge. Schmitt-trigger, filtered input for noise suppression. |+| 7 | WP | input | Write Protect input. Tie to GND for normal read/write operation. Tie to VCC to hardware write-protect the full 2K memory array. |+| 8 | VCC | power_in | Positive supply voltage input. Single-supply operation; decouple to GND with a 100 nF ceramic capacitor close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | BL Shanghai Belling |+| Package | SOP-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `BL24C02F-PARCPARC`++## CAD (KiCad official)++- Symbol: `BL24C02F-PARC`+- 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:** [BL Shanghai Belling datasheet](docs/bl24c02f-parc-datasheet.pdf) (20 pp, sha256 `279bd9046304e739`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
