The IS24CXX (IS24C16-2, IS24C16-3, IS24C08-2 and IS24C08-3) family is a low-cost and low voltage 2-wire Serial EEPROM. It is fabricated using ISSI's advanced CMOS EEPROM technology and provides a low power and low voltage operation. The IS24CXX family features a write protection feature, and is available in 8-pin DIP and 8-pin SOIC packages.
