Description

The AT25080B/160B provides 8192/16384 bits of serial electrically-erasable program-

mable read-only memory (EEPROM) organized as 1024/2048 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 AT25080B/160B is available

in space-saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead Ultra Thin Mini-MAP (MLP

2x3) and 8-lead TSSOP packages.

The AT25080B/160B 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.
