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

RESET/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

user’s system from low voltage conditions, resetting the

system when V

point. RESET/RESET is asserted until V

proper operating level and stabilizes. Four industry

standard V

sil’s unique circuits allow the threshold to be repro-

grammed to meet custom requirements or to fine-tune

the threshold for applications requiring higher precision.
