Working Principles

The AT24C128-10TU-1.8-T utilizes EEPROM technology, which employs floating-gate transistors to store and retrieve data. When data is written, an electric charge is trapped in the floating gate, altering the transistor's behavior. This charge can be removed during the erasing process, allowing the transistor to return to its original state. The stored data can be accessed by sending appropriate commands through the I2C interface.

The AT24C128-10TU-1.8-T finds applications in various fields, including:

1. Embedded systems: Used for storing configuration data and firmware updates in microcontrollers.
2. Industrial automation: Enables storage of calibration data and parameter settings in control systems.
3. Automotive electronics: Utilized for storing vehicle-specific information and user preferences.
4. Consumer electronics: Provides non-volatile memory for devices like smart TVs, set-top boxes, and gaming consoles.
5. Medical devices: Used for storing patient data, device configurations, and firmware updates.
