CAT24C163(16K), CAT24C083(8K)

CAT24C043(4K), CAT24C023(2K)

DESCRIPTION

The CAT24CXX3 is a single chip solution to three popular functions of EEPROM memory, precision reset controller and watchdog timer. The 24C163(16K), 24C083(8K), 24C043(4K) and 24C023(2K) feature a I2C Serial CMOS EEPROM Catalyst advanced CMOS technology substantially reduces device power requirements.The 24CXX3 features a 16-byte page and is available in 8-pin DIP or 8-pin SOIC packages.The reset function of the 24CXX3 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. 24CXX3 features active low reset on pin 2 and active high reset on pin 7. 24CXX3 features watchdog timer on the WDI input pin (pin 1).
