Description  
AT24C128  
AT24C256  
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 EIAJ, 8-pin JEDEC SOIC, 14-pin  
TSSOP, 8-pin LAP, and 8-ball dBGA packages. In addition, the entire family is avail-  
able in 5.0V (4.5V to 5.5V), 2.7V (2.7V to 5.5V), 2.5V (2.5V to 5.5V) and 1.8V (1.8V to  
3.6V) versions.
