Some of microcontroller have limited storage like Arduino it has only bytes data space compare to AT24C has Kb EEPROM will be very suitable for small amount of data storage or extending data storage for your microcontroller. The 24C is optimized for use in minimal storage applications where low-power and low-voltage operation, driven using i2C serial communication bus to help you do much more multiple series of storage. As you can see the diagram above the pin A0, A1, A2 are connected to the ground these pins allow you to customize the device i2C bus address, below the data sheet we that we verify how it is formed the byte address. For more details Please refer to the Datasheet below. See the address of the device below. The Wire library allows you to pass an integer value so we could just make a bit-wise operation to device the integer variable into two bytes.

These devices offer the designer different low voltage and low power options. They conform to all requirements in the Extended IIC 2-wire protocol. Furthermore, they are designed to minimize device pin count and simplify PC board layout requirements. Functional address lines allow up to eight devices on the same bus, for up to a total of 2 Mbit address space.
