Renesas / Dialog AT25SF041B 4Mbit SPI Serial Flash Memory

Renesas / Dialog AT25SF041B 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 AT25SF041B architecture includes erase block sizes optimized to meet current code and data storage applications and three security register pages for unique device serialization, system-level Electronic Serial Number (ESN) storage, and locked key storage.
