AT25DF011 Datasheet

Description

The AT25DF011 is a serial interface Flash memory device for use in 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 AT25DF011, with its page erase granularity, is also ideal for data

storage, eliminating the need for additional data storage devices.

The erase block sizes of the AT25DF011 have been optimized to meet the needs of today's 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 sectored and 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 also contains a specialized One-Time Programmable (OTP) Security Register that can be used for

unique device serialization, system-level Electronic Serial Number (ESN) storage, locked key storage, etc.

Designed for use in many different systems, the AT25DF011 supports read, program, and erase operations with a

wide supply voltage range of 1.65 V to 3.6 V. No separate voltage is required for programming and erasing.
