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 aI2C  
Serial CMOS EEPROM Catalyst advanced CMOS tech-  
nologysubstantiallyreducesdevicepowerrequirements.  
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  
duringbrownoutandpowerup/downconditions. 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).
