ESP8266EX Integrated Wifi SoC – QFN-32

Espressif’s ESP8266EX delivers highly integrated WiFi System on Chip (SoC) solution to meet users’ continuous demands for efficient power usage, compact design and reliable performance in the Internet of Things industry.

With the complete and self-contained WiFi networking capabilities, ESP8266EX can perform either as a standalone application or as the slave to a host MCU. When ESP8266EX hosts the application, it promptly boots up from the flash. The integrated high speed cache helps to increase the system performance and optimize the system memory. Also, ESP8266EX can be applied to any micro controller design as a WiFi adapter through SPI / SDIO or UART interfaces.

ESP8266EX integrates antenna switches, RF balun, power amplifier, low noise receive amplifier, filters and power management modules. The compact design minimizes the PCB size and requires minimal external circuits.

Besides the WiFi functionalities, ESP8266EX also integrates an enhanced version of Tensilica’s L106 Diamond series 32-bit processor and on-chip SRAM. It can be interfaced with external sensors and other devices through the GPIOs. Software Development Kit (SDK) provides sample codes for various applications.
