Description

The ESP8089 offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to off-load all Wi-Fi networking functions from another application processor.
When ESP8089 hosts the application, it is usually the only application processor in the device, with the user’s applications stored in an internal/external Flash. Alternately, serving as a Wi-Fi adapter, wireless internet access can be added to any microcontroller-based design with simple connectivity through the SPI/SDIO interface or the CPU AHB bridge interface
