DESCRIPTION

The CAT24C323/643 is a single chip solution to three

popular functions of EEPROM memory, precision reset

controller and watchdog timer. The 24C323(32K) and

24C643 (64K) feature a I²C Serial CMOS EEPROM

Catalyst advanced CMOS technology substantially re-

duces device power requirements. The 24C323/643

features a 32-byte page and is available in 8-pin DIP or

8-pin SOIC packages.

The reset function of the 24C323/643 protects the sys-

tem during brown out and power up/down conditions.

During system failure the watchdog timer feature pro-

tects the microcontroller with a reset signal. 24C323

features active low reset on pin 2 and active high reset

on pin 7. 24C323/643 features watchdog timer on the

WDI input pin (pin 1).
