Description

The AT25DF161-SH-B is one member of the AT25DF161 series.It has the following features including (1)automatic checking and reporting of erase/program failures;(2)JEDEC standard manufacturer and device ID read methodology;(3)complies with full industrial temperature range;(4)endurance: 100,000 program/erase cycles.

The AT25DF161 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 AT25DF161, with its erase granularity as small as 4-Kbytes,makes AT25DF161-SH-B 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 AT25DF161 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. AT25DF161-SH-B increased memory space efficiency allows additional code routines and data storage segments to be added while still maintaining the same overall device density.

The AT25DF161 also offers a sophisticated method for protecting individual sectors against erroneous or malicious program and erase operations. By providing the ability to individually protect and unprotect sectors, a system can unprotect a specific sector to modify its contents while keeping the remaining sectors of the memory array securely protected. AT25DF161-SH-B is useful in applications where program code is patched or updated on a subroutine or module basis, or in applications where data storage segments need to be modified without running the risk of errant modifications to the program code segments. In addition to individual sector protection capabilities,the AT25DF161 incorporates Global Protect and Global Unprotect features that allow the entire memory array to be either protected or unprotected all at once. This reduces overhead during the manufacturing process since sectors do not have to be unprotected one-by-one prior to initial programming.
