Description  
The AT25128A/256A provides 131,072/262,144 bits of serial electrically-erasable  
programmable 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 appli-  
cations 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-ball dBGA2 and 8-lead SAP 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.  
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  
Serial Clock (SCK). All programming cycles are completely self-timed, and no sepa-  
rate Erase cycle is required before Write.
