Description  
The AT25080A/160A/320A/640A provides 8192/16384/32768/65536 bits of serial  
electrically-erasable programmable read-only memory (EEPROM) organized as  
1024/2048/4096/8192 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 AT25080A/160A/320A/640A is available in space-saving 8-lead  
PDIP, 8-lead JEDEC SOIC, 8-lead MAP, and 8-lead TSSOP packages.

The AT25080A/160A/320A/640A 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 separate erase cycle is required before write.
