The CAT24CXXX is a single chip solution to three popular functions of EEPROM memory, precision reset controller and watchdog timer. The 24C321/322(32K) and 24C641/642(64K) feature a I2C Serial CMOS EEPROM. Catalyst's advanced CMOS technology sub stantially reduces device power requirements. The 24CXXX features a 32-byte page and is available in 8-pin DIP or 8-pin SOIC packages.
