24LC04BT-E from Microchip Tech, in a SOT-23-5. 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 | SCL | input | Serial clock input used to synchronize data transfer to and from the device. |
| 2 | VSS | power_in | Ground reference for the device. |
| 3 | SDA | bidirectional | Open-drain serial address/data I/O that requires a pull-up resistor to VCC (typically 10 kΩ for 100 kHz and 2 kΩ for 400 kHz and 1 MHz). |
| 4 | VCC | power_in | Power supply input, 2.5V to 5.5V for the 24LC04B. |
| 5 | WP | input | Write-protect input: tied to VSS enables normal read/write of the full memory, while tied to VCC inhibits all write operations. |
