DESCRIPTION
These devices combine four popular functions, Power-on
Reset Control, Watchdog Timer, Supply Voltage Supervi-
sion, and Block Lock Protect Serial EEPROM Memory
in one package. This combination lowers system cost,
reduces board space requirements, and increases reli-
ability.
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 microcontrol-
ler 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 Vcc detection circuitry protects the
user’s system from low voltage conditions, resetting the
system when Vcc falls below the minimum Vcc trip point.
RESET/RESET is asserted until Vcc returns to proper
operating level and stabilizes. Five industry standard
V
TRIP
thresholds are available, however, Xicor’s unique
circuits allow the thresold to be reprogrammed to meet
custom requirements or to fine-tune the threshold for
applications requiring higher precision.
