The CAT24CXXX is a single chip solution to three popular functions of EEPROM memory, precision reset controller and watchdog timer. The 24C161/162(16K), 24C081/082(8K), 24C041/042(4K) and 24C021/022(2K) feature a I2C Serial CMOS EEPROM. Catalyst's advanced CMOS technology substantially reduces device power requirements. The 24CXXX features a 16-byte page and is available in 8-pin DIP or 8-pin SOIC packages. The reset function of the 24CXXX protects the system during brown out and power up/down conditions. During system failure the watchdog timer feature protects the microcontroller with a reset signal. 24CXXX features active low reset on pin 2 and active high reset on pin 7. 24CXX1 features watchdog timer on the SDA line. 24CXX2 does not feature the watchdog timer function.
