Working Principles

AT24C128W-10SI-1.8 utilizes an I2C interface to communicate with the host device. It stores data in a memory array organized as 16384 bytes. The device can be addressed using three address pins (A0, A1, A2), allowing up to eight devices to be connected on the same bus.

To write data, the device requires a start condition, followed by the device address and memory address. The data is then transmitted serially and stored in the specified memory location. Reading data follows a similar process, where the device address and memory address are provided, and the requested data is read from the memory array.
