General Description
The AT25EU0011A is 1-Mbit Serial Peripheral Interface (SPI) Flash memory, designed for a wide variety of high-volume consumer-based applications in which program code is shadowed from Flash memory into embedded or external RAM for execution. The flexible erase architecture of the device, with its page erase granularity, is ideal for data storage as well, eliminating the need for additional data storage devices.

The erase block sizes of the device have been optimized to meet the needs of todays code and data storage applications. By optimizing the size of the erase blocks, the memory space can be used much more efficiently. Because certain code modules and data storage segments must reside by themselves in their own erase regions, the wasted and unused memory space that occurs with large block erase Flash memory devices can be greatly reduced. This increased memory space efficiency allows additional code routines and data storage segments to be added while still maintaining the same overall device density.

The device uses a single low-voltage power supply, ranging from 1.65 V to 3.6 V, and supports JEDEC standard manufacturer and device ID, a 128-bit Unique Serial Number, and three 512-bytes Security Registers.
