ESP8266EX - Tiny Wireless 802.11 b/g/n Chip

Designed for use in Internet of Things (IoT), mobile, and wearable electronics applications, the wireless ESP8266EX chip is a highly integrated, low-power Wi-Fi solution. It provides extremely low-power consumption and occupies minimal PCB area. It reaches a maximum clock speed of 160 MHz. The minimal wake up time feature can be utilized by mobile device SOCs which allows them to remain in low-power standby mode until Wi-Fi is needed.

Highly integrated, this compact chip has

• 32-bit Tensilica processor
• Standard digital peripheral interfaces
• antenna switches
• RF balun
• Power amplifier
• Low noise amplifier
• Power management modules

With the 32-bit low power micro-controller (MCU), this EXP8266  Wi-Fi chip is often  integrated with external sensors and other application-specific devices through its 17 GPIO pins. It can host an application or offload 802.11 Wi-Fi networking functions from another application processor.

Examples of major applications include:

• Home automation
• Smart lights and plugs
• Home appliances
• IP cameras
• Baby monitors
• Sensor networks
• Security ID tags
• Mesh networks
• Industrial wireless control
• Wearable electronics
• Wi-Fi location-aware devices
• Wi-Fi position system beacons
