DESCRIPTION
The X40626 combines four popular functions, Power-on
Reset Control, Watchdog Timer, Dual Supply Voltage
Supervision, and Serial EEPROM Memory in one pack-
age. This combination lowers system cost, reduces
board space requirements, and increases reliability.
Applying power to the device activates the power on
reset circuit which holds RESET active for a period of
time. This allows the power supply and oscillator to stabi-
lize before the processor can execute code.
The Watchdog Timer provides an independent protection
mechanism for microcontrollers. When the microcontrol-
ler fails to restart a timer within a selectable time-out
interval, the device activates the RESET signal. The user
selects the interval from three preset values. Once
selected, the interval does not change, even after cycling
the power.
The device’s low V

system when V

falls below the set minimum V
point. RESET is asserted until V
