Working Principles

The 24AA32A-I/S16K is based on EEPROM technology, which utilizes floating-gate transistors to store and retrieve data. When writing data, an electric charge is applied to the floating gate, altering its electrical characteristics. This change in charge determines the stored data. During read operations, the charge level of the floating gate is measured, allowing the retrieval of stored information.
