Description

The AT25128/256 provides 131,072/262,144 bits of serial electrically-erasable pro-

grammable 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 JEDEC SOIC (AT25128) and 8-pin

EIAJ SOIC (AT25256) packages. In addition, the entire family is available in 5.0V

AT25128

AT25256

(4.5V to 5.5V) and 2.7V (2.7V to 5.5V) versions.
