Description
Three-state DATA output for configuration. Open-collector bi-directional pin for
programming.
Clock input. Used to increment the internal address and bit counter for reading and
programming.
RESET/Output Enable input (when SER_EN is High). A Low level on both the CE and
RESET/OE inputs enables the data output driver. A High level on RESET/OE resets
both the address and bit counters. The logic polarity of this input is programmable as
either RESET/OE or RESET/OE. This document describes the pin as RESET/OE.
Write protect (WP) input (when CE is Low). When WP is Low, the entire memory can
be written. When WP is enabled (High), the lowest block of the memory cannot be
written. This feature is only active in the 2-wire serial Programming Mode (i.e., when
SER_EN is Low; see “Programming Specification” application note for more details).
Chip Enable input. Used for device selection. A Low level on both CE and OE enables
the data output driver. A High level on CE disables both the address and bit counters
and forces the device into a low-power standby mode. Note that this pin will not
enable/disable the device in the 2-wire Serial Programming Mode (i.e., when SER_EN
is Low).
Ground pin. A 0.2 µF decoupling capacitor between VCC and GND is recommended.
Chip Enable Output. This signal is asserted Low on the clock cycle following the last bit
read from the memory. It will stay Low as long as CE and OE are both Low. It will then
follow CE until OE goes High. Thereafter, CEO will stay High until the entire EEPROM
is read again.
Device selection input, A2. This is used to enable (or select) the device during
programming (i.e. when SER_EN is Low; see the “Programming Specification”
application note for more details.
Serial enable must be held High during FPGA loading operations. Bringing SER_EN
Low enables the 2-wire Serial Programming Mode.

*NOTICE:
Stresses beyond those listed under Absolute
Maximum Ratings may cause permanent dam-
age to the device. This is a stress rating only and
functional operation of the device at these or any
other conditions beyond those listed under oper-
ating conditions is not implied. Exposure to Abso-
lute Maximum Rating conditions for extended
periods of time may affect device reliability.
