24AA64-E 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 | input | Chip address input that must be tied to VCC or VSS (or driven to a logic 0 or 1 by a controller) before normal operation and is compared with the client address bits to select the chip. |
| 2 | A1 | input | Chip address input that must be tied to VCC or VSS (or driven to a logic 0 or 1 by a controller) before normal operation and is compared with the client address bits to select the chip. |
| 3 | A2 | input | Chip address input that must be tied to VCC or VSS (or driven to a logic 0 or 1 by a controller) before normal operation and is compared with the client address bits to select the chip. |
| 4 | VSS | power_in | Ground reference for the device. |
| 5 | SDA | bidirectional | Open-drain serial address/data I/O that requires a pull-up resistor to VCC (typically 10 kΩ for 100 kHz, 2 kΩ for 400 kHz and 1 MHz) and may change only while SCL is low, except for Start and Stop conditions. |
| 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 connected to VSS (write operations enabled) or VCC (write operations inhibited, read operations unaffected). |
| 8 | VCC | power_in | Power supply input; the 24AA64 operates from 1.7V to 5.5V per the device selection table. |
