AT25128A

AT25256A

Description

The AT25128A/256A provides 131,072/262,144 bits of serial electrically-erasable pro-

grammable 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

2.7V (2.7V to 5.5V) and 1.8V (1.8V to 5.5V) versions.

The AT25128A/256A is enabled through the Chip Select pin (CS) 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 sepa-

rate Erase cycle is required before Write.
