Description

The AT25DF321A 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 AT25DF321A, 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.
