24AA025UIDT-I from Microchip Tech, in a SOT-23-6. 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 synchronizes data transfer to and from the device, operating at 100 kHz and 400 kHz clock compatibility (100 kHz for VCC < 2.5V). |
| 2 | VSS | power_in | Ground reference pin for the device. |
| 3 | SDA | bidirectional | Serial Address/Data I/O is an open-drain terminal that requires a pull-up resistor to VCC (typically 10 kΩ for 100 kHz, 2 kΩ for 400 kHz). |
| 4 | A1 | input | Chip Address Input compared with the corresponding slave address bit; must be connected to either VSS or VCC. |
| 5 | A0 | input | Chip Address Input compared with the corresponding slave address bit; must be connected to either VSS or VCC. |
| 6 | VCC | power_in | Power supply, +1.7V to 5.5V. |
