ESP8266EX - Wi-Fi IC with on-board Microcontroller

The Espressif ESP8266EX is a low-power, highly-integrated Wi-Fi solution measuring just 5mm x 5mm. The tiny ESP8266EX includes an on-board 32-bit microcontroller from Tensilica (MCU) which features extra low power consumption and 16-bit RISC processor.

The Espressif ESP8266EX is a low-power, highly-integrated Wi-Fi solution measuring just 5mm x 5mm. The tiny ESP8266EX includes an on-board 32-bit microcontroller from Tensilica (MCU) which features extra low power consumption and 16-bit RISC processor, capable of reaching a maximum clock speed of 160 MHz. With the Real Time Operation System (RTOS) enabled and Wi-Fi stack functional, about 80% of the processing power is still available for user application programming and development making it ideal from small, low power designs.
