1. Description

The AT26F004 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 shad-

owed from Flash memory into embedded or external RAM for execution. The flexible

erase architecture of the AT26F004, 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 AT26F004 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.
