Working Principles

The AT24C04A-10PI-2.5 utilizes EEPROM technology to store and retrieve data. It consists of a grid of memory cells that can be individually addressed for read or write operations. When data is written, an electric charge is applied to specific memory cells, altering their state. This altered state represents the stored data. During read operations, the stored data is retrieved by sensing the state of each memory cell.

Detailed Application Field Plans

The AT24C04A-10PI-2.5 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 other peripherals for non-volatile storage.
3. Consumer Electronics: Integrated into devices like smart TVs, set-top boxes, and digital cameras for data storage.
