Working Principles

The 25AA080B-I/P utilizes a floating gate transistor technology to store data in its non-volatile memory cells. The EEPROM memory cells can be electrically programmed and erased using the SPI interface. When data needs to be written, the device receives the data through the SI pin and stores it in the appropriate memory location. Reading data involves shifting the desired memory address to the device and retrieving the stored data from the SO pin.
