Working Principles

The 24LC024-I/SN is based on EEPROM technology, which utilizes floating gate transistors to store and retrieve data. When data needs to be written, a high voltage is applied to the gate, allowing electrons to tunnel through the insulating layer and become trapped in the floating gate. This alters the transistor's threshold voltage, representing a logical "1" or "0". To read the stored data, the transistor's threshold voltage is measured, determining the stored value.

Detailed Application Field Plans

The 24LC024-I/SN is commonly used in various electronic devices that require non-volatile memory for storing configuration settings, calibration data, or small amounts of user data. Some specific application fields include:

1. Consumer Electronics: Used in smart TVs, set-top boxes, and audio/video equipment for storing user preferences and system configurations.
2. Industrial Automation: Employed in programmable logic controllers (PLCs) and industrial control systems for storing parameter settings and program data.
3. Automotive Electronics: Integrated into automotive modules for storing vehicle-specific data, such as VIN numbers, mileage, and diagnostic information.
4. Medical Devices: Utilized in medical equipment for storing patient data, device settings, and calibration values.
5. Internet of Things (IoT): Incorporated into IoT devices for storing sensor data, network configurations, and firmware updates.
