AT25320B  
AT25640B  
Description  
The AT25320B/640B provides 32768/65536 bits of serial electrically-erasable pro-  
grammable read-only memory (EEPROM) organized as 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 AT25320B/640B is  
available in space-saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead Ultra Thin Mini-  
MAP (MLP 2x3), 8-lead Ultra Lead Frame Land Grid Array (ULA) and 8-lead TSSOP  
packages.  
Advance  
Information  
The AT25320B/640B 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.
