Working Principles

The AT24C64-10TC-2.7 utilizes an electrically controlled floating gate to store and retrieve data. When data is written, an electrical charge is applied to the floating gate, altering its conductivity. This charge can be removed during the erase process, allowing the cell to be rewritten. The memory cells are organized into pages, which can be individually accessed for read or write operations.

Detailed Application Field Plans

The AT24C64-10TC-2.7 finds application in various fields, including:

1. Microcontrollers: Used for storing program code, configuration settings, and calibration data.
2. Computers: Employed in BIOS chips, expansion cards, and embedded systems for non-volatile storage.
3. Consumer Electronics: Integrated into devices like smart TVs, set-top boxes, and digital cameras for data storage.
