Working Principles

The AT93C86-10PC-2.7 utilizes EEPROM technology, which employs floating gate transistors to store and retrieve data. When writing data, an electrical charge is applied to the floating gate, altering its electrical characteristics. This charge can be removed during erasure, allowing the transistor to return to its original state. The stored data is accessed by applying appropriate voltage levels to the control pins and reading the resulting electrical signals.
