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
