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.

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.

  1. Request for Linux Kernel Modules for DA16600MOD UART Interface (Wi-Fi and BLE) Integration with RZG3S

    Hello Renesas Community, We are currently working on integrating the DA16600MOD Wi-Fi and Bluetooth module into our custom-made system that uses the RZG3S processor. Our system is designed to use only the UART interface to interface with the DA16600MOD for Wi-Fi (UART0) and BLE communication. Could anyone ...
