Working Principles

The AT25320AN-10SI-2.7-T is based on EEPROM technology, which allows for electrically erasing and reprogramming of data. It utilizes a serial interface (SPI) to communicate with a microcontroller or host device. The chip select signal (/CS) is used to enable the device, and the serial clock (SCK) synchronizes the data transfer. Data can be written to or read from the memory using the serial data input (SI) and output (SO) pins. The write protect (/WP) pin provides an additional layer of security by preventing accidental writes. The device operates within a specified voltage range and retains data even when power is removed.
