• Relatively slow write cycle time: The 5 ms write cycle time may introduce delays in applications that require frequent data updates.

Working Principles

The AT24C04AN-10SC utilizes electrically erasable programmable read-only memory (EEPROM) technology. It stores data by trapping electric charges within a floating gate structure. These charges can be selectively removed or added using electrical signals, allowing for data modification.

During operation, the chip communicates with the host device through the I2C interface. The host device sends commands and addresses to read from or write to specific memory locations within the chip. The AT24C04AN-10SC responds accordingly, retrieving or modifying the requested data.

Detailed Application Field Plans

The AT24C04AN-10SC finds applications in various electronic devices, including but not limited to:

1. Consumer electronics: Used for storing configuration settings, user preferences, and other non-volatile data in devices such as televisions, audio players, and home appliances.
2. Automotive systems: Employed in automotive electronics for storing critical data like calibration values, vehicle settings, and fault codes.
3. Industrial control systems: Utilized in industrial automation and control systems for storing parameters, calibration data, and program code.
4. Medical devices: Integrated into medical equipment for storing patient data, device settings, and firmware updates.
