Description
The AT24C128/256 provides 131,072/262,144 bits of serial electrically erasable and
programmable read only memory (EEPROM) organized as 16,384/32,768 words of 8
bits each. The device
’
s cascadable feature allows up to four devices to share a com-
mon 2-wire bus. 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 JEDEC PDIP, 8-lead EIAJ, 8-lead JEDEC SOIC,
14-lead TSSOP, and 8-pad LAP 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.
