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  
available in space-saving 8-pin JEDEC PDIP, 8-pin JEDEC SOIC, 8-pin EIAJ SOIC, 8-  
pin TSSOP, 14-pin TSSOP and 8-ball dBGA packages. In addition, the entire family is  
available in 2.7V (2.7V to 5.5V) and 1.8V (1.8V to 3.6V) versions.
