tracks the unregulated supply to provide a power fail
warning or monitors different power supply voltage.
Three common low voltage combinations are available,
however, Xicor’s unique circuits allows the threshold for
either voltage monitor to be reprogrammed to meet
special needs or to ne-tune the threshold for applica-
tions requiring higher precision.
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 Xicor’s Block Lock protection. The
array is internally organized as x 8. The device features
a 2-wire interface and software protocol allowing opera-
tion on an I2C bus.
The device utilizes Xicor’s proprietary Direct Write
cell, providing a minimum endurance of 100,000 cycles
and a minimum data retention of 100 years.
Triple Voltage Monitors
*Voltage monitor requires VCC to operation. Others are independent of VCC.

V2FAIL V2 Voltage Fail Output. This open drain output goes LOW when V2MON is less than VTRIP2 and
goes HIGH when V2MON exceeds VTRIP2. There is no power up reset delay circuitry on this pin.
24
V2MON V2 Voltage Monitor Input. When the V2MON input is less than the VTRIP2 voltage, V2FAIL goes
LOW. This input can monitor an unregulated power supply with an external resistor divider or can
monitor a second power supply with no external components. Connect V2MON to VSS or VCC
when not used.The V2MON comparator is supplied by V2MON (X40410/11) or by VCC Input
(X40414/15).
35
RESET/
RESET
RESET Output. (X40411/15) This is an active LOW, open drain output which goes active when-
ever VCC falls below VTRIP1. It will remain active until VCC rises above VTRIP1 and for the tPURST
thereafter.
RESET Output. (X40410/14) This is an active HIGH CMOS output which goes active whenever
VCC falls below VTRIP1. It will remain active until VCC rises above VTRIP1 and for the tPURST there-
after.
