Espressif Systems ESP82x Single-Core Wi-Fi SoCs

Espressif Systems ESP82x Wi-Fi System-on-Chips (SoCs) offer complete, self-contained Wi-Fi networking solutions for IoT (Internet of Things) applications. The ESP8266 and ESP8285 SoCs integrate a Tensilica L106 32-bit Microcontroller Unit (MCU), which features extra-low power consumption and 16-bit RSIC reaching a maximum clock speed of 160MHz. With the Real-Time Operating System (RTOS) enabled and a functional Wi-Fi stack, about 80% of the processing power is available for user application programming and development.

ESP8266EX and ESP8285 SoCs include standard digital peripheral interfaces, antenna switches, RF balun, power amplifier, low noise receive amplifier, filters, and power management modules, all in a tiny package. These devices offer reliability, compactness, and robustness with the highly-integrated on-chip features and minimal external discrete component count.
