Description  
AT25128A  
AT25256A  
The AT25128A/256A provides 131,072/262,144 bits of serial electrically-erasable pro-  
grammable read only memory (EEPROM) organized as 16,384/32,768 words of 8 bits  
each. 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-lead PDIP, 8-lead EIAJ SOIC, 8-lead JEDEC SOIC, 8-lead TSSOP,  
8-lead Leadless Array 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 5.5V) versions.  
Preliminary  
The AT25128A/256A is enabled through the Chip Select pin (CS) and accessed via a  
3-wire interface consisting of Serial Data Input (SI), Serial Data Output (SO), and  
8-lead TSSOP
