ESP8266 WiFi SoC offers a complete and self-contained Wi-Fi networking solution it can be used to

host the application or to offload Wi-Fi networking functions another application processor.

When ESP8266 hosts the application, it boots up directly an external flash. In has integrated

cache to improve the performance of the system in such applications. Alternately, serving as a Wi-Fi

adapter, wireless internet access can be added to any microcontroller-based design with simple

connectivity through UART interface or the CPU AHB bridge interface.-ESP8266 WiFi SoC offers a complete and self-contained Wi-Fi networking solution　it can be used to
