ESP8266EX - Wi-Fi SoC Chip, SMD QFN32-Reel - ESPRESSIF

ESP8266EX – Highly Integrated Wi-Fi SoC (32-bit MCU, TCP/IP stack)

The ESP8266EX is one of Espressif Systems’ most iconic and widely used Wi-Fi chips, which has revolutionized the development of IoT devices. It is a highly integrated SoC (System-on-a-Chip) that incorporates a 32-bit processor, the complete Wi-Fi radio frequency unit, and the TCP/IP protocol stack, enabling it to function either as a standalone controller or as a Wi-Fi adapter for other microcontrollers.

Key Product Features

• High-Performance Processor: Tensilica L106 32-bit RISC microprocessor with a clock speed of up to 160 MHz and an ultra-low-power architecture.
• Full Wi-Fi functionality: 2.4 GHz Wi-Fi (802.11 b/g/n) support, with integrated TR switch, balun, LNA, and power amplifier.
• Super-low power consumption: Special power-saving modes (e.g., Deep-sleep) that reduce current consumption to below 20 μA, making it ideal for battery-powered devices.
• Compact package: 5 x 5 mm QFN32 package that requires minimal space on the printed circuit board.
• Extensive interface set: Numerous pins (GPIO, UART, SPI, I2C, I2S, PWM) and a 10-bit ADC for direct connection to sensors.
