DESCRIPTION
These devices combine four popular functions, Power-on
Reset Control, Watchdog Timer, Supply Voltage
Supervision, and Block Lock
Protect Serial EEPROM
Memory in one package. 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

from three preset values. Once selected, the interval
does not change, even after cycling the power.
