Working Principles

The 25AA080T/SN operates based on the Serial Peripheral Interface (SPI) protocol. It uses a clock signal (SCK) to synchronize data transfer between the device and the host microcontroller. The host initiates communication by enabling the chip select (/CS) pin, followed by sending commands and data through the serial data input (SI) pin. The device responds by providing requested data through the serial data output (SO) pin. Write operations are performed by sending appropriate commands and data to the device.
