24LC08B from Microchip Tech, 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 | unconnected | Not used by the 24XX08 (no internal connection); may be left floating or tied to VSS or VCC. |
| 2 | A1 | unconnected | Not used by the 24XX08 (no internal connection); may be left floating or tied to VSS or VCC. |
| 3 | A2 | unconnected | Not used by the 24XX08 (no internal connection); may be left floating or tied to VSS or VCC. |
| 4 | VSS | power_in | Ground. |
| 5 | SDA | bidirectional | Serial address/data I/O; open-drain bidirectional pin that requires a pull-up resistor to VCC (typical 10 kΩ for 100 kHz, 2 kΩ for 400 kHz and 1 MHz). |
| 6 | SCL | input | Serial clock input used to synchronize data transfer to and from the device. |
| 7 | WP | input | Write-protect input that must be tied to VSS (normal read/write of entire memory 000-3FF) or VCC (write operations inhibited, reads unaffected). |
| 8 | VCC | power_in | Power supply; 2.5V to 5.5V for the 24LC08B. |
