Description  
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 automotive applications  
where low-power and low-voltage operation are essential. The devices are available in  
space-saving 8-lead PDIP, 8-lead JEDEC SOIC, and 8-lead TSSOP packages.  
AT25128A  
AT25256A  
The AT25128A/256A is enabled through the Chip Select pin (CS) and accessed via a  
three-wire interface consisting of Serial Data Input (SI), Serial Data Output (SO), and  
Serial Clock (SCK). All programming cycles are completely self-timed, and no sepa-  
rate erase cycle is required before write.
