Memory & Logic

Overview

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.

  • Quad enabled at the factory
  • Universally compatible pinout and command set
  • Standard block architecture
  • Continuous read, wrap and burst modes for XiP
