*NOTICE: Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The AT25010/020/040 provides 1024/2048/4096 bits of serial electrically erasable programmable read only memory (EEPROM) organized as 128/256/512 words of 8 bits each. The AT25040 is optimized for use in many industrial and commercial applicat ions where low power and low voltage operation are essential. TheAT25010/020/040 is available in space saving 8-pin PDIP and 8-pin JEDEC (SOIC) packages.

The AT25010/020/040 is enabled through the Chip Select pin (CS) and accessed via a 4-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.
