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 protection
mechanism for microcontrollers. When the microcon-
troller fails to restart a timer within a selectable time out
interval, the device activates the 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
CC
falls below the minimum V
RESET/RESET is asserted until V
operating level and stabilizes. Five industry standard
V
TRIP
thresholds are available, however, Xicor’s unique
circuits allow the threshold to be reprogrammed to meet
custom requirements or to fine-tune the threshold for
applications requiring higher precision.
CC
detection circuitry protects the
CC
trip point.
