Overview
Description
The AT25SF128A is a member of our standard class code and data storage solutions designed for 3V systems in which program code is shadowed from Flash memory into embedded or external RAM for execution.
The architecture includes erase block sizes that are optimized to meet the needs of today's code and data storage applications and three security register pages for unique device serialization, system-level Electronic Serial Number (ESN) storage, locked key storage, etc.
- Universally compatible pinout and command set
- Standard block architecture
- Supports Dual I/O, Quad I/O and XiP operation
- Continuous read, wrap and burst modes for XiP
