Description

The Adesto? AT25DF512C 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 AT25DF512C, 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 AT25DF512C 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 AT25DF512C supports read, program, and erase operations with a

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