management modules, it requires minimal external circuitry, and the entire solution,
including front-end module, is designed to occupy minimal PCB area.
ESP8266EX also integrates an enhanced version of Tensilica’s L106 Diamond series 32-bit
processor, with on-chip SRAM, besides the Wi-Fi functionalities. ESP8266EX is often
integrated with external sensors and other application specific devices through its GPIOs;
codes for such applications are provided in examples in the SDK.
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.
