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  
automotive applications where low-power and low-voltage operation are essential.  
The AT25080A/160A/320A/640A is available in space saving 8-lead PDIP and 8-lead  
JEDEC SOIC packages.

AT25640A  
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.  
Block write protection is enabled by programming the status register with one of four  
blocks of write protection. Separate program enable and program disable instructions  
are provided for additional data protection. Hardware data protection is provided via  
the WP pin to protect against inadvertent write attempts to the status register. The  
HOLD pin may be used to suspend any serial communication without resetting the  
serial sequence.
