Gizwits IoT Technology ES8266A1T1 User Manual
Overview
1.
The ES8266 A1T1 offers a complete and s
to either host the application or to offload all Wi-Fi networking functions from another application
processor.
When The ES8266 A1T1 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 A1T1 on-board proc
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
essing and storage capabilities allow it to be integrated with
elf-contained Wi-Fi networking solution, allowing it
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.
