Working Principles

The AT25080A-10PU-2.7 operates based on the Serial Peripheral Interface (SPI) protocol. It uses a clock signal (SCK) and serial data lines (SI/O and SO) to communicate with a microcontroller or host device. The chip select (/CS) pin is used to enable or disable the device.

Data can be written to the EEPROM memory in byte or page-level increments. The write protect (/WP) pin allows software or hardware-based protection against accidental writes. The hold (/HOLD) pin suspends ongoing operations without resetting the internal state.

During standby mode, the AT25080A-10PU-2.7 consumes minimal power. When active, it efficiently transfers data between the memory and the host device.
