DESCRIPTION
This device combines three popular functions, Power-
on Reset, Watchdog Timer, and Supply Voltage
Supervision in one package. This combination lowers
system cost, reduces board space requirements, and
increases reliability.
The watchdog timer provides an independent protec-
tion mechanism for microcontrollers. During a system
failure, the device will respond with a RESET signal
after a selectable time out interval. The user selects the
interval from three preset values. Once selected, the
interval does not change, even after cycling the power.
The user’s system is protected from low voltage condi-
tions by the device’s low V CC detection circuitry. When
V CC falls below the minimum V CC trip point, the system
is reset. RESET is asserted until V CC returns to proper
operating levels and stabilizes. Five industry standard
V TRIP thresholds are available, however, Intersil’s
unique circuits allow the threshold to be reprogrammed
to meet custom requirements or to fine-tune the thresh-
old for applications requiring higher precision.
The device utilizes Intersil’s proprietary Direct Write ?
cell for the watchdog timer control bits and the V TRIP
storage element, providing a minimum endurance of
100,000 write cycles and a minimum data retention of
100 years.
