Supervisory Circuits with I2C Serial CMOS E2PROM, Precision Reset Controller and Watchdog Timer
FEATURES
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 I

C
Serial CMOS EEPROM Catalyst advanced CMOS tech-
nology 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).
