FEATURES
DESCRIPTION
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 I
2
C Serial CMOS EEPROM. Catalyst's ad-
vanced 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.
