DESCRIPTION

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).
