24AA1026-I from Microchip Tech, in a PDIP-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 internally. |
| 2 | A1 | input | User-configurable chip address input compared with the slave address bit; must be hard-wired or driven to logic 0 or 1 before operation, allowing up to four devices on one bus. |
| 3 | A2 | input | User-configurable chip address input compared with the slave address bit; must be hard-wired or driven to logic 0 or 1 before operation, allowing up to four devices on one bus. |
| 4 | VSS | power_in | Ground. |
| 5 | SDA | bidirectional | Serial data open-drain bidirectional pin for addresses and data, requiring 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 (writes enabled) or VCC (writes inhibited, reads unaffected). |
| 8 | VCC | power_in | Supply voltage: +1.7 to 5.5V (24AA1026), +2.5 to 5.5V (24LC1026), +1.8 to 5.5V (24FC1026). |
