**HANSCHIP semiconductor** · EEPROM · SOIC-8

HX24LC08BDRG from HANSCHIP semiconductor, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A0 | input | Address input; not used (no connect, may be tied to ground) on the 8K HX24LC08B. |
| 2 | A1 | input | Address input; not used (no connect, may be tied to ground) on the 8K HX24LC08B. |
| 3 | A2 | input | Device address input, the only hard-wire address pin used by the 8K HX24LC08B, so two devices may share a bus. |
| 4 | GND | power_in | Ground. |
| 5 | SDA | bidirectional | Serial data, bidirectional open-drain pin that may be wire-ORed with other open-drain or open-collector devices. |
| 6 | SCL | input | Serial clock input that clocks data into the device on the positive edge and out on the negative edge. |
| 7 | WP | input | Write protect: at GND allows normal read/write, at VCC protects the full 8K array. |
| 8 | VCC | power_in | Power supply, 1.7V to 5.5V. |
