The AT25QL128A is a member of our standard class code and data storage solutions designed for low-voltage systems in which program code is shadowed from Flash memory into embedded or external RAM for execution. The architecture includes standard erase block sizes and a security register for unique device serialization, system-level Electronic Serial Number (ESN) storage, locked key storage, etc. The AT25QL128A is Quad enabled at the factory and offers a universally compatible pinout and command set, standard block architecture, and continuous read, wrap, and burst modes for XiP.
