DESCRIPTION
The CAT24CXXX is a single chip solution to three
popular functions of EEPROM memory, precision reset
controller and watchdog timer. The 24C321/322(32K)
and 24C641/642(64K) feature a I
2
C Serial CMOS
EEPROM. Catalyst's advanced CMOS technology sub-
stantially reduces device power requirements. The
24CXXX features a 32-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.
24C321/641 features watchdog timer on the SDA line.
24C322/642 does not feature the watchdog timer func-
tion.
