DESCRIPTION
The X4163/5 combines four popular functions, Power-
on Reset Control, Watchdog Timer, 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/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 protec-
tion mechanism for microcontrollers. When the micro-
controller fails to restart a timer within a selectable
time
out
interval,

RESET/RESET signal. The user selects the interval
from three preset values. Once selected, the interval
does not change, even after cycling the power.
