space saving 8-pin PDIP (AT25128/256), 8-pin EIAJ SOIC
(AT25128/256), 8-pin and 16-pin JEDEC SOIC (AT25128),
14-pin TSSOP (AT25128), 20-pin TSSOP (AT25128/256),
and 8-pin Leadless Array (AT25128/256) packages. In
addition, the entire family is available in 5.0V (4.5V to
5.5V), 2.7V (2.7V to 5.5V) and 1.8V (1.8V to 3.6V) ver-
sions.
The AT25128/256 is enabled through the Chip Select pin
(CS) and accessed via a 3-wire interface consisting of
Serial Data Input (SI), Serial Data Output (SO), and Serial
Clock (SCK). All programming cycles are completely self-
timed, and no separate ERASE cycle is required before
WRITE.
BLOCK WRITE protection is enabled by programming the
status register with top ¼, top ½ or entire array of write pro-
tection. Separate program enable and program disable
instructions are provided for additional data protection.
Hardware data protection is provided via the WP pin to pro-
tect against inadvertent write attempts to the status regis-
ter. The HOLD pin may be used to suspend any serial
communication without resetting the serial sequence.

device. This is a stress rating only and functional
operation of the device at these or any other condi-
tions beyond those indicated in the operational sec-
tions of this specification is not implied. Exposure to
absolute maximum rating conditions for extended
periods may affect device reliability.

Description
The AT25128/256 provides 131,072/262,144 bits of serial electrically erasable programmable read only memory (EEPROM) organized as 16,384/32,768 words of 8 bits each. The device is optimized for use in many industrial and commercial applications where low power and low voltage operation are essential. The devices are available in space saving 8-pin PDIP (AT25128/256), 8-pin EIAJ SOIC (AT25128/256), 8-pin and 16-pin JEDEC SOIC (AT25128), 14-pin TSSOP (AT25128), 20-pin TSSOP (AT25128/256), and 8-pin Leadless Array (AT25128/256) packages. In addition, the entire family is available in 5.0V (4.5V to 5.5V), 2.7V (2.7V to 5.5V) and 1.8V (1.8V to 3.6V) versions.
