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 the chip's I2C slave address. Up to eight HX24C02 devices may share one bus by strapping A0-A2 uniquely. |+| 2 | A1 | input | Device address input bit 1. Hard-wired to VCC or GND to set the chip's I2C slave address. |+| 3 | A2 | input | Device address input bit 2. Hard-wired to VCC or GND to set the chip's I2C slave address. |+| 4 | GND | power_in | Ground reference for the device. |+| 5 | SDA | bidirectional | Serial data line for the two-wire I2C interface. Open-drain output; requires an external pull-up resistor to VCC. Bi-directional for reads and writes to the EEPROM array. |+| 6 | SCL | input | Serial clock input for the two-wire I2C interface. Positive edge clocks data into the EEPROM; negative edge clocks data out. Max 1 MHz at VCC = 5V; 400 kHz at 1.8V/2.5V/2.7V. |+| 7 | WP | input | Write Protect input. Tied to GND for normal read/write operation. Tied to VCC to hardware-protect the entire 2K array against write operations. |+| 8 | VCC | power_in | Positive supply voltage input. Operating range 1.7 V to 5.5 V. Recommend a 0.1 uF decoupling capacitor close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HANSCHIP semiconductor |+| Package | SOP-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `HX24C02DRG`+- `HX24C02DRGPG`+- `HX24C02DRGDGKRG`+- `HX24C02DRGDBVRG`+- `HX24C02DRGDDFRG`++## CAD (KiCad official)++- Symbol: `HX24C02DRG`+- 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:** [HANSCHIP semiconductor datasheet](docs/hx24c02drg-datasheet.pdf) (17 pp, sha256 `8b39cc16ac1b07de`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
