Description  
AT24C128(1)  
AT24C256(2)  
Notes: 1. Not recommended for  
new design; please  
refer to AT24C128B  
datasheet.  
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  
Two-wire bus. The device is optimized for use in many industrial and commercial appli-  
cations where low power and low voltage operation are essential. The devices are  
available in space-saving 8-lead JEDEC PDIP, 8-lead JEDEC SOIC, 8-lead EIAJ  
SOIC, 8-lead MAP (24C128), 8-lead TSSOP, 8-lead SOIC Array Package and 8-ball  
dBGA2 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.
