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
Pin Configurations
14-Lead TSSOP
Rev. 0872E–08/98
*Note: Pins 3, 4 and 17, 18 are internally connected for 14-lead TSSOP socket compatibility.
