DESCRIPTION

The IS24CXX (refers to IS24C01, IS24C02, IS24C04, IS24C08, IS24C16) 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.
