Description
The AT25DF041A 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 AT25DF041A, 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.
