256Kbit, SPI Bus Serial EEPROM, High speed, supports Mode 0 and 3.

The AT25128B/256B provides 131,072/262,144 bits of serial electrically-erasable programmable read only memory (EEPROM) organized as 16,384/32,768 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 devices are available in space saving 8-lead PDIP, 8-lead EIAJ SOIC, 8-lead JEDEC SOIC, 8-lead TSSOP, 8-ball dBGA2 and 8-lead SAP packages. In addition, the entire family is available in 1.8V (1.8V to 5.5V).

The AT25128B/256B is enabled through the Chip Select pin () 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 separate Erase cycle is required before Write.
