Specifications

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.
