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 4 devices to share a common  
2-wire bus. The device is optimized for use in many industrial and commercial applica-  
tions where low power and low voltage operation are essential. The devices are avail-  
able in space-saving 8-pin JEDEC PDIP, 8-pin EIAJ, 8-pin JEDEC SOIC, 14-pin  
TSSOP, and 8-pin 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.
