24LC256T-I from Microchip Tech, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A0 | input | User configurable chip select input that must be connected to VCC or VSS to define the lower bit of the device slave address. |
| 2 | A1 | input | User configurable chip select input that must be connected to VCC or VSS to define the middle bit of the device slave address. |
| 3 | A2 | input | User configurable chip select input that must be connected to VCC or VSS to define the upper bit of the device slave address. |
| 4 | VSS | power_in | Ground connection serving as the negative supply reference and return path for all device currents. |
| 5 | SDA | bidirectional | Bidirectional open-drain serial data line for I2C bus used to transfer addresses and data, requiring external pull-up resistor to VCC (10 kΩ @ 100 kHz, 2 kΩ @ 400 kHz/1 MHz). |
| 6 | SCL | input | Serial clock input for I2C bus used to synchronize data transfer to and from the device. |
| 7 | WP | input | Write protect input that enables write operations when connected to VSS or inhibits write operations when connected to VCC. |
| 8 | VCC | power_in | Positive supply voltage with operating range of +2.5V to +5.5V for this 24LC256 device variant. |
