High Level of Integration
ESP8266EX is among the most integrated Wi-Fi chips in the industry. Measuring just 5mm x 5mm, ESP8266EX requires minimal external circuitry and integrates 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.
32-bit Tensilica MCU
ESP8266EX integrates Tensilica L106 32-bit micro controller (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 Wi-Fi stack functional, about 80% of the processing power is still available for user application programming and development.
Low Power Management
Engineered for mobile devices, wearable electronics and the Internet of Things (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, thus allowing battery-powered designs to run longer.
Featuring the widest operating temperature range of -40°C to +125°C in the industry, ESP8266EX is capable of functioning in industrial environments. With highly integrated on-chip features and minimal external discrete component count, the chip offers reliability, compactness and robustness critical in end products.
