The AT25DF081 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 AT25DF081, 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 AT25DF081 have been optimized
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 additional
code routines and data storage segments to be added while still maintaining the
same overall device density.
