DESCRIPTION
The X40430, X40431, X40434, X40435 combines
power-on reset control, watchdog timer, supply voltage
supervision, second and third voltage supervision,
manual reset, and Block Lock ? protect serial EEPROM
in one package. This combination lowers system cost,
reduces board space requirements, and increases
reliability.
Applying voltage to V CC activates the power-on reset
circuit which holds RESET/RESET active for a period of
time. This allows the power supply and system oscilla-
tor to stabilize before the processor can execute code.
Low V CC detection circuitry protects the user’s system
from low voltage conditions, resetting the system
when V CC falls below the minimum V TRIP1 point.
RESET/RESET is active until V CC returns to proper
operating level and stabilizes. A second and third volt-
age monitor circuit tracks the unregulated supply to
provide a power fail warning or monitors different
power supply voltage. Three common low voltage
combinations are available. However, Intersil’s unique
circuits allows the threshold for either voltage monitor
to be reprogrammed to meet specific system level
requirements or to fine-tune the threshold for applica-
tions requiring higher precision.
A manual reset input provides debounce circuitry for
minimum reset component count.
The Watchdog Timer provides an independent protec-
tion mechanism for microcontrollers. When the micro-
controller fails to restart a timer within a selectable
time out interval, the device activates the WDO signal.
The user selects the interval from three preset values.
Once selected, the interval does not change, even
after cycling the power.
The memory portion of the device is a CMOS Serial
EEPROM array with Intersil’s Block Lock protection.
The array is internally organized as x 8. The device
features a 2-wire interface and software protocol
allowing operation on an I 2 C bus.
The device utilizes Intersil’s proprietary Direct Write ?
cell, providing a minimum endurance of 100,000
cycles and a minimum data retention of 100 years.
