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

are essential. The AT25080/160/320/640 is available in space saving 8-lead PDIP, 8-

lead JEDEC SOIC and 14-lead TSSOP packages.

The AT25080/160/320/640 is enabled through the Chip Select pin (CS) and accessed

via a 3-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-

(continued)

rate ERASE cycle is required before WRITE.
