Atmel AT25080B
Description
The Atmel ? AT25080B/160B provides 8192/16384 bits of serial electrically-erasable
programmable 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 JEDEC SOIC, 8-lead UDFN, 8-lead TSSOP, 8-lead
XDFN, and 8-ball VFBGA 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.
