Working Principles

The AT24C512W-10SU-1.8 utilizes EEPROM technology to store digital information. It consists of a memory array organized into multiple pages, each containing a fixed number of bytes. The chip communicates with an external microcontroller or host device using the I2C serial interface.

To write data, the microcontroller sends the desired memory address along with the data to be stored. The chip then stores the data in the specified location. Reading data follows a similar process, where the microcontroller provides the memory address, and the chip retrieves and transmits the corresponding data.
