Description
The Adesto® AT25DN256 is a serial interface Flash memory device designed 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 AT25DN256, with its page erase granularity it is ideal for data storage as well, eliminating the
need for additional data storage devices.
The erase block sizes of the AT25DN256 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 OTP (One-Time Programmable) Security Register that can be used for purposes such as
unique device serialization, system-level Electronic Serial Number (ESN) storage, locked key storage, etc.
Specifically designed for use in many different systems, the AT25DN256 supports read, program, and erase operations with a
wide supply voltage range of 2.3V to 3.6V. No separate voltage is required for programming and erasing.
