AT25DF161
Preliminary
1. Description
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 shad-
owed 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 it ideal for data storage as well, eliminating the need for additional data storage
EEPROM devices.
