The 24LC128-I/SN is an I2C-compatible EEPROM with a pin count of 8. Its primary functions include:
1. Power Supply (VCC): Pin 8 - Connects to the positive supply voltage (typically 2.5V to 5.5V).
2. Ground (GND): Pin 4 - Connects to the ground.
3. Serial Data (SDA): Pin 2 - Bidirectional data line for I2C communication.
4. Serial Clock (SCL): Pin 3 - Clock line for synchronizing data transfer.
5. Write Protect (WP): Pin 1 - Activates write protection when tied to VCC; otherwise, allows writing.
6. NC (Not Connected): Pins 5, 6, and 7 - No connection; not used for the device's operation.
This device provides 128 Kbits of memory and supports I2C interface with standard and fast mode.
