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.
