1. Overview The ES8266 A101 offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. When The ES8266 A101 hosts the application, and when it is the only application processor in the device, it is able to boot up directly from an external flash. It has integrated cache to improve the performance of the system in such applications, and to minimize the memory requirements. 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. The ES8266 A101 on-board processing and storage capabilities allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. With its high degree of on-chip integration, which includes the antenna switch balun, power management converters, it requires minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area. Sophisticated system-level features include fast sleep/wake context switching for energy-
efficient VoIP, adaptive radio biasing for low-power operation, advance signal processing, and spur cancellation and radio co-existence features for common cellular, Bluetooth, DDR, LVDS, LCD interference mitigation. 2.

Peak Temperature : <250C Number of Times : 2 times ESD CAUTION The ES8266 A101 is ESD (electrostatic discharge) sensitive device and may be damaged with ESD or spike voltage. Although ES8266 A101 is with built-in ESD protection circuitry, please handle with care to avoid the permanent malfunction or the performance degradation. The host will Satisfy Class I or Class permissive change based this module FCC ID. If the FCC identification number is not visible when the module is installed inside the host, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: Contains Transmitter Module Contains FCC ID:2ASLM-ES8266A101 or Contains FCC ID:2ASLM-
ES8266A101 .Any similar wording that expresses the same meaning may be used. 20C
