Working Principles

The AT24C04AN-10SC-1.8 operates based on the principles of electrically erasable programmable read-only memory (EEPROM). It utilizes a floating-gate transistor structure to store and retrieve data. When a voltage is applied, electrons are trapped in the floating gate, representing a logical "1" state. Conversely, when the voltage is removed, the absence of trapped electrons represents a logical "0" state. By selectively applying voltages and controlling the charge on the floating gate, data can be written, erased, and read from the chip.

The AT24C04AN-10SC-1.8 finds applications in various fields, including:

1. Microcontrollers: Used for storing configuration settings, calibration data, and firmware updates.
2. Computers: Employed in BIOS chips for storing system configuration data.
3. Consumer Electronics: Integrated into devices like smart TVs, set-top boxes, and digital cameras for storing user preferences and settings.
4. Automotive: Utilized in electronic control units (ECUs) for storing critical vehicle data, such as mileage and diagnostic information.
5. Industrial Automation: Used in programmable logic controllers (PLCs) for storing program code and configuration parameters.
