Embedded Wi-Fi® Products Microchip is the leader in the fast-growing embedded Wi-Fi market, offering innovative, ultra-low-power wireless solutions for monitoring and controlling products over home networks or across the global internet. Our products are used in many applications including sensors, home automation, machine-to-machine control, and asset tracking to name but a few. Microchip’s Wi-Fi Portfolio Microchip has a broad portfolio of Wi-Fi products including complete, 802.11 b/g modules, certified radio transceivers, and RF chipset solutions that make adding Wi-Fi simple. Our modules have modular radio certifications and include full TCP/IP stacks and networking services, all in a compact, surface mount component to save you development time and testing cost. With UART, SPI slave, general purpose I/O and analog inputs, our modules provide multiple hardware interfaces. In addition to the TCP/UDP protocol, we support all the common networking services including: ■ WPS (Wi-Fi Protected Setup) ■ Web Server for confi guration and general purpose ■ FTP (File Transport Protocol) ■ HTTP (Hypertext Transfer Protocol) ■ Wi-Fi Direct ■ DHCP client and server ■ DNS (Domain Name Service) ■ SSL (Secure Socket Level) ■ mDNS (Bonjour/Zero Confi g) ■ SMTP (Simple Mail Transfer Protocol) Support for additional services and the ability to customize service and stack function are possible with the networking source code provided. Key Features ■ Ultra-low-power for battery-powered applications ■ Over-the-air fi rmware upgrade ■ Supports SoftAP, Ad hoc, Infrastructure networking modes ■ Hardware interfaces: UART and SPI Slave ■ Secure Wi-Fi authentication schemes (WEP/WPA/WPA2/Enterprise/EAP) ■ Broad range of IP services ■ Complete web service support Wireless Product Solutions Applications With full 802.11g over-the-air data rates of 54 mbps and user data throughput up to 5 mbps, these modules are perfect for embedded applications that send files or small amounts of data. The ultra-low, 30–40 mA receive current and multiple sleep modes of 4 μA or lower make batterypowered Wi-Fi applications possible. Embedded Wi-Fi applications include: ■ Remote equipment monitoring ■ Asset tracking and telemetry ■ Security ■ Industrial sensors and controls ■ Home automation ■ Medical devices Modular Certifi cations Microchip Wi-Fi modules carry the following modular certifications: ■ FCC United States ■ IC Industry Canada ■ EN European Union ■ KC Korea ■ NCC Taiwan ■ Telec Japan The Wi-Fi Alliance insures interoperability with other Wi-Fi Alliance certified equipment.
