AT25DF041A
1. 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.
