X40626
The device’s low V CC detection circuitry protects the
user’s system from low voltage conditions, resetting the
system when V CC falls below the set minimum V CC trip
point. RESET is asserted until V CC returns to proper
operating level and stabilizes. Four industry standard
Vtrip thresholds are available. However, Intersil’s unique
circuits allow the threshold to be reprogrammed to meet
custom requirements or to fine-tune the threshold for
The device utilizes Intersil’s proprietary Direct Write ?
cell, providing a minimum endurance of 100,000 page
write cycles and a minimum data retention of 100 years.

applications requiring higher precision.
The memory portion of the device is a CMOS Serial
EEPROM array with Intersil’s Block Lock ? Protection.
The array is internally organized as 64 bytes per page.
The device features an 2-wire interface and software pro-
tocol allowing operation on an I 2 C bus.

Reset Output . RESET is an active LOW, open drain output which goes active whenever V CC
falls below the minimum V CC sense level. It will remain active until V CC rises above the mini-
mum V CC sense level for typically 200ms. RESET goes active if the Watchdog Timer is
enabled and SDA remains either HIGH or LOW longer than the selectable Watchdog time-out
period. A falling edge on SDA, while SCL is HIGH, resets the Watchdog Timer. RESET goes
active on power-up and remains active for typically 200ms after the power supply
stabilizes.
Ground
Serial Data. SDA is a bidirectional pin used to transfer data into and out of the device. It has an
open drain output and may be wire ORed with other open drain or open collector outputs. This
pin requires a pull up resistor and the input buffer is always active (not gated).
Watchdog Input. A HIGH to LOW transition on the SDA (while SCL is HIGH) restarts the Watch-
dog timer. The a bsenc e of a HIGH to LOW transition within the watchdog time-out
period results in RESET going active.
Serial Clock. The Serial Clock controls the serial bus timing for data input and output.
V2 Voltage Fail Output. This open drain output goes LOW when V2MON is less than V TRIP2
and goes HIGH when V2MON exceeds V TRIP2 . There is no power-up reset delay circuitry on
this pin. This circuit works independently from the Low V CC reset and battery switch circuits.
Connect V2FAIL to VSS when not used.
V2 Voltage Monitor Input. When the V2MON input is less than the V TRIP2 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 V SS or V CC when not used. There is no hysteresis in the V2MON comparator circuits.
Write Protect. WP HIGH used in conjunction with WPEN bit prevents writes to the control reg-
ister.
