1. Description  
The AT26DF161 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 AT26DF161, 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 AT26DF161 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.
