Renesas / Dialog AT25SF161B 16Mbit SPI Serial Flash Memory

Renesas / Dialog AT25SF161B 4Mbit SPI Serial Flash Memory is part of the Renesas standard class code and data storage solutions. The solution design is developed for 3V systems in which program code is followed from Flash memory into embedded or external RAM for execution.

The Renesas / Dialog AT25SF161B is a serial interface Flash memory device created for various high-volume consumer-based applications. The flexible erase architecture of the AT25SF161B is also excellent for data storage, eliminating the requirement for additional data storage devices.
