24LC02BT-E from Microchip, 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 | unconnected | Not connected internally on the 24XX02. May be left floating or tied to either VSS or VCC. Present on the package for pin-compatibility with larger-density 24-series EEPROMs where this pin is a device-address input. |
| 2 | A1 | unconnected | Not connected internally on the 24XX02. May be left floating or tied to either VSS or VCC. Present on the package for pin-compatibility with larger-density 24-series EEPROMs where this pin is a device-address input. |
| 3 | A2 | unconnected | Not connected internally on the 24XX02. May be left floating or tied to either VSS or VCC. Present on the package for pin-compatibility with larger-density 24-series EEPROMs where this pin is a device-address input. |
| 4 | VSS | power_in | Ground reference for the device. Connect to the system ground rail. |
| 5 | SDA | bidirectional | Serial Address/Data I/O for the two-wire (I2C-compatible) interface. Open-drain output; requires an external pull-up resistor to VCC (typical 10 kΩ at 100 kHz, 2 kΩ at 400 kHz / 1 MHz). Schmitt-trigger input with slope-controlled output. |
| 6 | SCL | input | Serial Clock input for the two-wire (I2C-compatible) interface. Used by the host to synchronize data transfer to and from the device. Schmitt-trigger input; supports 100 kHz and 400 kHz operation on 24LC02B. |
| 7 | WP | input | Hardware Write-Protect input. Must be tied to either VSS or VCC. Tied to VSS enables normal read/write operation across the entire memory (00h-FFh); tied to VCC inhibits all write operations (entire array becomes write-protected while reads remain unaffected). |
| 8 | VCC | power_in | Positive supply voltage. Operating range 2.5V to 5.5V for the 24LC02B variant. Typical operating current is 1 mA (read) / 3 mA (write) at 400 kHz; standby current is <=1 µA (I-temp) / <=5 µA (E-temp) with SDA=SCL=VCC and WP=VSS. |
