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 | SCL | input | Serial Clock input for the 2-wire (I2C-compatible) bus. Command and input data on SDA are latched on the rising edge of SCL, while output data on SDA is clocked out on the falling edge. Schmitt-trigger, filtered input. |+| 2 | GND | power_in | Ground reference for the power supply. Must be connected to system ground. |+| 3 | SDA | bidirectional | Serial Data bidirectional pin for the 2-wire (I2C-compatible) bus. Open-drain output that requires an external pull-up resistor to VCC. Schmitt-trigger, filtered input. |+| 4 | VCC | power_in | Device power supply, 1.7V to 5.5V. Operations at invalid VCC voltages may produce spurious results. Bypass with a decoupling capacitor to GND. |+| 5 | WP | input | Write Protection input. When tied to VCC, the entire memory array becomes write-protected (device is read-only). When tied to GND, write operations are enabled. Internally pulled down to GND if left floating. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HANSCHIP semiconductor |+| Package | SOT-23-5 |+| Category | Memory |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `AT24C02CDBVRG`+- `AT24C02CDBVRGCPG`+- `AT24C02CDBVRGCDRG`+- `AT24C02CDBVRGCDRG4`+- `AT24C02CDBVRGCDGKRG`+- `AT24C02CDBVRGCPWRG`+- `AT24C02CDBVRGCRG`++## CAD (KiCad official)++- Symbol: `AT24C02CDBVRG`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HANSCHIP semiconductor datasheet](docs/at24c02cdbvrg-datasheet.pdf) (27 pp, sha256 `30146010ee8ac6eb`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
