64Kbit, SPI Bus Serial EEPROM, High speed, supports Mode 0 and 3.

The 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 PDIP, 8-lead JEDEC SOIC, 8-lead Ultra Thin Mini- MAP (MLP 2x3), 8-lead Ultra Lead Frame Land Grid Array (ULA) and 8-lead TSSOP 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 separate erase cycle is required before write.
