ESP8266 / ESP8285 SoC

32-bit Tensilica MCU

ESP8266EX integrates a Tensilica L106 32-bit microcontroller unit (MCU), which features extra-low power consumption and 16-bit RSIC, reaching a maximum clock speed of 160 MHz. With the Real Time Operation System (RTOS) enabled and a functional Wi-Fi stack, about 80% of the processing power is still available for user application programming and development.

Power-Saving Architecture

Engineered for mobile devices, wearable electronics and IoT applications, ESP8266EX achieves low power consumption with a combination of several proprietary technologies. The power-saving architecture features three modes of operation: active mode, sleep mode and deep sleep mode. This allows battery-powered designs to run longer.

Compactness

ESP8266EX is highly integrated with a 32-bit Tensilica MCU, standard digital peripheral interfaces, antenna switches, RF balun, power amplifier, low noise receive amplifier, filters and power management modules—all in one small package.

High Durability

ESP8266EX is capable of functioning consistently in industrial environments, due to its wide operating temperature range. With highly-integrated on-chip features and minimal external discrete component count, the chip offers reliability, compactness and robustness.
