Working Principles

The AT25320T1-10TC-2.7 operates based on the principles of EEPROM technology. It utilizes a floating-gate transistor structure to store and retrieve data. When data is written, an electrical charge is trapped in the floating gate, altering the transistor's behavior. This charge can be removed during the erase operation, allowing the transistor to return to its original state.

The Serial Peripheral Interface (SPI) protocol is used for communication between the AT25320T1-10TC-2.7 and the host microcontroller or system. The SPI interface provides clock and data lines for synchronous serial communication, enabling efficient and reliable data transfer.
