AT25SF641B-SHB-B Datasheet - Dialog Semiconductor

Product Overview
The Adesto® AT25SF641B is a serial interface Flash memory device designed for use in a wide variety of highvolume 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 AT25SF641B also is ideal for data storage, eliminating the need for additional data storage devices.
