CAT24C323(32K), CAT24C643 (64K)

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 I
2C Serial CMOS EEPROM Catalyst advanced CMOS technology substantially reduces 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 system during brown out and power up/down conditions.During system failure the watchdog timer feature protects 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).
