Product description
ESP8266 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 ESP8266 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.
ESP8266 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.
