Working Principles

The AT24C1024BW-SH25-T utilizes EEPROM technology, which allows for electrically erasing and programming data. It consists of a grid of memory cells that can be individually addressed for read and write operations. The data is stored in the form of electrical charges within these cells, which can be modified by applying appropriate voltage levels.

During a write operation, the desired memory location is selected, and the data to be written is sent through the I2C interface. The internal circuitry then applies the necessary voltage levels to store the data in the selected memory cell. Similarly, during a read operation, the requested memory location is addressed, and the stored data is retrieved via the I2C interface.
