Working Principles

AT24C64W-10SI-2.7 utilizes electrically erasable floating-gate transistors to store data. The memory cells are organized into a grid-like structure, with each cell capable of storing one bit of information. Data can be written to or read from individual memory cells using the I2C interface.

During a write operation, the desired memory location is addressed, and the data to be written is sent serially through the SDA line. The data is then stored in the selected memory cell by applying appropriate voltage levels. Reading data follows a similar process, where the addressed memory location is specified, and the data is retrieved from the corresponding memory cell.
