Working Principles

The 24LC08BH-I/ST utilizes EEPROM technology, which employs floating-gate transistors to store data. When writing data, an electrical charge is applied to the floating gate, altering its threshold voltage and allowing the transistor to represent either a "0" or a "1". To erase data, a higher voltage is applied to remove the charge from the floating gate, resetting the transistor's state.

The 24LC08BH-I/ST finds applications in various fields, including:

1. Embedded Systems: Used for storing configuration data, firmware updates, and user settings in microcontroller-based systems.
2. Automotive Electronics: Employed for storing critical data, such as vehicle identification numbers (VINs) and calibration parameters.
3. Industrial Automation: Utilized for storing production data, sensor calibration values, and system configurations.
4. Consumer Electronics: Found in devices like smart TVs, set-top boxes, and gaming consoles for storing user preferences and application data.
