Overview
Description
The AT25SL128A 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.
- Universally compatible pinout and command set
- Standard block architecture
- Continuous read, wrap and burst modes for XiP

AT25SL128A went into protected sector state
Hello, I have a design based on AT25SL128A. I started with the standardflash.c and tests for it from the Adesto github website and all tests pass. So I assume my SPI integration is fine on my MCU. I then set it running for a longer test so that it ...
