Description
The AT25080/160/320/640 provides 8192/16384/32768/65536 bits of serial electri-
cally 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
