AT25DF641-MWH-Y

Flash Mem Serial-SPI 3.3V 64M-Bit 5ns 8Pin VDFN Bulk

Description

The AT25DF641 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 external RAM for execution. The flexible erase architecture of the AT25DF641, 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.
