ESP8266 is a highly integrated chip designed for the needs of a new connected world. It 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. ESP8266 has powerful on-board processing and storage capabilities that 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. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area. Features SDIO 2.0, SPI, UART 32-pin QFN package Integrated RF switch, balun, 24dBm PA, DCXO, and PMU Integrated RISC processor, on-chip memory and external memory interfaces Integrated /baseband processors Quality of Service management I2S interface for high fidelity audio applications On-chip low-dropout linear regulators for all internal supplies Proprietary spurious-free clock generation architecture Integrated WEP, TKIP, AES, and WAPI engines Solutions Supports APSD for optimal VoIP applications Patented spurious noise cancellation algorithm for integration in SOC applications Supports Bluetooth co-existence interface Self-calibrated RF to ensure optimal performance under all operating conditions Zero factory tuning No external RF components
