24AA02E48-I 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 | NC | unconnected | Not connected on the 24AA02E48 (A0 address input position on the 24AA025E48); may be left floating or tied to VSS or VCC. |
| 2 | NC | unconnected | Not connected on the 24AA02E48 (A1 address input position on the 24AA025E48); may be left floating or tied to VSS or VCC. |
| 3 | NC | unconnected | Not connected on the 24AA02E48 (A2 address input position on the 24AA025E48); 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 terminal that needs a pull-up resistor to VCC (typically 10 kΩ for 100 kHz, 2 kΩ for 400 kHz). |
| 6 | SCL | input | Serial clock input that synchronizes data transfer to and from the device. |
| 7 | NC | unconnected | Not connected. |
| 8 | VCC | power_in | Power supply, +1.7V to 5.5V. |
