Working Principles

The 24AA512/S16K utilizes EEPROM technology, which is based on floating-gate transistors. These transistors can trap and store electrical charges, representing binary data. The stored charges can be erased or programmed by applying appropriate voltage levels to the memory cells.

During a write operation, the desired data is sent to the chip through the I2C interface. The data is then stored in the specified memory location by modifying the charge level of the corresponding memory cell. Reading data involves retrieving the stored charges and converting them back into binary values.
