Working Principles

The AT93C86A-10SU-2.7 chip utilizes EEPROM technology to store and retrieve data. It consists of an array of memory cells that can be electrically programmed and erased. The chip operates by applying specific voltage levels to control gates and floating gates within each memory cell. These voltage levels determine whether the memory cell stores a logical 0 or 1.

During write operations, data is transferred serially into the chip and stored in the appropriate memory cells. Reading data involves sequentially accessing the memory cells and retrieving the stored information.
