1. Description

The AT25DF041A 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 AT25DF041A, with its erase granularity as small as

4 Kbytes, makes it ideal for data storage as well, eliminating the need for additional

data storage EEPROM devices.

The physical sectoring and the erase block sizes of the AT25DF041A have been opti-

mized to meet the needs of today’s code and data storage applications. By optimizing

the size of the physical sectors and 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 protected sectors, 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 addi-

tional code routines and data storage segments to be added while still maintaining the

same overall device density.
