Working Principles

AT93C66AW-10SU-1.8 utilizes EEPROM technology, which allows for electrically erasing and reprogramming of data. The memory cells within the chip store information in the form of electrical charges. When data needs to be written or modified, the appropriate voltage levels are applied to the specific memory cells. The stored charge represents the binary state of each memory cell, allowing for reliable data retrieval even after power loss.
