Cpu Supervisor With 64k Eeprom Inc.The X4643 X4645 combines four popular functions, Power-on
Reset Control, Watchdog Timer Supply Voltage
Supervision, and Serial EEPROM Memory in one
package. This combination lowers system cost,
reduces board space requirements, and increases reli-
ability.
Applying power to the device activates the power on
reset circuit which holds RESET/RESET active for a
period of time. This allows the power supply and oscilla-
tor to stabilize before the processor CAN execute code.
The Watchdog Timer provides an independent protection
mechanism for Microcontrollers When the microcon-
troller fails to restart a Timer within a selectable time out
interval, the device activates the RESET/RESET signal.
The user selects the interval from three preset values.
Once selected, the interval does not change, even after
cycling the power. By Intersil Corporation
