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 protec-
tion mechanism for microcontrollers. When the micro-
controller 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.
