Description
The Atmel
®
AT25320B/640B provides 32768-/65536-bits of serial electrically-erasable
programmable read-only memory (EEPROM) organized as 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 AT25320B/640B is
available in space-saving 8-lead JEDEC SOIC, 8-lead UDFN, 8-lead XDFN, 8-lead
TSSOP, and 8-ball VFBGA packages.
The AT25320B/640B 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.
