IoT Wi-Fi Devices Machete Down Power Consumption

Silicon Labs’ latest Wi-Fi devices promise to simplify the design of power-sensitive, battery-operated Wi-Fi products including IP security cameras, point-of-sale (PoS) terminals and consumer health care devices. Optimized for energy efficiency, the WF200 transceivers and WFM200 modules support 2.4 GHz 802.11 b/g/n Wi-Fi.

 

Developers can speed time to market and miniaturize battery-operated Wi-Fi products with the WFM200, described as the market's smallest pre-certified system-in-package (SiP) module with an integrated antenna. The WF200 transceiver provides a cost-effective option for high-volume applications and gives developers the flexibility to meet unique system design requirements, such as using external antennas.

SENSORS EXPO & CONFERENCE

Sensors 2018 Hits Silicon Valley June 26-28!

Join thousands of engineers this June in San Jose at the sensor industry’s biggest event! With 65+ Technical Sessions, 100+ Leading Speakers, and 300+ Interactive Exhibits, there’s more opportunity than ever to connect with this booming industry and the technologies driving it. See thousands of the newest technologies in action, learn about the latest applications, including AI, Autonomous Vehicles, IoT, and Medical, and develop invaluable partnerships at the only event dedicated to sensors, connectivity, and systems.

 

WF200 transceiver and WFM200 module features include:

  • Low transmit (TX: 138 mA) and receive (RX: 48 mA) power
  • 200 µA average Wi-Fi power consumption (DTIM = 3) contributing to ultra-low system power
  • Superior link budget of 115 dBm for long-range Wi-Fi transmissions
  • Small-footprint 4 mm x 4 mm QFN32 transceiver and 6.5 mm x 6.5 mm LGA52 SiP module, ideal for space-constrained applications
  • Excellent antenna diversity and wireless coexistence in crowded 2.4 GHz environments
  • Advanced security technology: secure boot and host interface, hardware cryptography acceleration supporting AES, PKE and TRNG
  • Pre-certification by the FCC, CE, IC, South Korea and Japan to minimize development time, effort and risk
  • Comprehensive development tools and wireless starter kit including embedded and Linux host drivers, enabling developers to get started in minutes

 

Silicon Labs is sampling WF200 transceivers and WFM200 SiP modules to selected customers, and production parts are planned for Q4 2018. For additional information, dive deeper into the features and specs.
