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
PIN CONFIGURATION
8-Pin JEDEC SOIC, MSOP, PDIP
features an 2-wire interface and software protocol
allowing operation on an I 2 C bus.
The device utilizes Intersil’s proprietary Direct Write ?

Reset Output . RESET is an active LOW, open drain output which goes active
whenever V CC falls below V TRIP . It will remain active until V CC rises above the
V TRIP for t PURST . RESET/RESET goes active if the Watchdog Timer is enabled
and SDA remains either HIGH or LOW longer than the selectable Watchdog time
out period. RESET/RESET goes active on power-uppower-up and remains
active for 250ms after the power supply stabilizes. RESET is an active high open
drain output. An external pull up resistor is required on the RESET/RESET pin.
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).
Serial Clock. The Serial Clock input controls the serial bus timing for data input and
output.
Write Protect. WP HIGH prevents writes to any location in the device (including
the control register). Connect WP pin to V SS when it is not used.
