The X2004JI25 is a 4Kbit Serial EEPROM manufactured by Xicor Inc. This EEPROM is organized as 512 x 8 bits and operates via a serial interface, typically SPI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit). Its primary function is non-volatile data storage, allowing data to be retained even when power is removed. The '25' likely refers to the speed grade, indicating a write cycle time in milliseconds. The X2004 is used in applications requiring small amounts of persistent data storage, like configuration settings, calibration data, or serial numbers.
