AT26DF161

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 ex ternal 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 increa sed memory space efficiency allows addi- tional code routines and data  storage segments to be added while still maintaining the same overall device density.
