    Synergy and Innovation

    As you probably have already learned, Microchip recently acquired Micrel, adding its strong portfolio of timing and communications products, linear and power management products and LAN solutions to our already extensive list of embedded control devices. We are now able to provide solutions for even more markets and applications with this exciting expansion to our business.

    The timing and communications products are new additions to our portfolio, giving us another opportunity to meet our customers design requirements. The linear and power management products enhance and complement our existing Analog product offerings. Expanding our portfolio of LAN and connectivity solutions by integrating the Micrel devices will allow us to provide a richer product selection sup-porting additional applications. In fact, in this issue of MicroSolutions, youll read about a new, single-chip 10Base-T/100Base-TX Ethernet physical-layer transceiver that comes to us via Micrel that provides uniquely low emissions and high immunity over low-cost Unshielded Twisted Pair (UTP) cables for automotive and industrial network connectivity.

    We believe that the synergy generated by the combined product lines of Microchip and Micrel will offer you an even broader range of innovative solutions to serve your specific design needs. We are pleased to announce that the Micrel products have all been incorporated into the Microchip website. Our global sales and support team is available to assist you with integrating the Micrel products into your projects. If you have any questions, feel free to reach out to your local Microchip office. The Micrel products are also now available for purchase on microchipDIRECT.

    Another exciting update from microchipDIRECT is that you can now contact the regional sales and support offices using new toll-free telephone numbers that will work in many of the countries that microchipDIRECT serves. Please visit the microchipDIRECT Regional Sales and Support page to find the toll-free number for your country.

    As always, we would be happy to get your feedback on MicroSolutions. Feel free to email us at MSFeedback@microchip.com.




    Wireless LoRa Technology: Ideal for Battery-Operated Sensor and Low-Power Internet of Things and Machine-to-Machine ApplicationsEnables Long-Range Connectivity, Longer Battery Life and Lower Costs

    With analysts predicting that there will be 25 billion connected things in use by 2020, the explosive growth of the Internet of Things (IoT) market is challenging developers to establish a simple, robust infrastructure with limited resources. They are seeking a solution that requires a minimum total cost of ownership and is easy to design. It should also offer a short time to market, great interoperability and flexible deployment options.

    To meet these demands, Microchip is pleased to partner with other members of the LoRa Alliance to help standardize the Low Power Wide Area Networks (LPWANs) being deployed around the world to enable IoT, Machine-to-Machine (M2M), smart city and indus-trial applications. These low-power applications have requirementsincluding long-range connectivity combined with long battery lifetimes and low cost

    COVER STORYfor volume deploymentthat cannot be fully served by other existing wireless technologies. Microchip has also launched the fully certified RN2483 LoRa Sub-GHz, 433/868 MHz European R&TTE Directive Assessed Radio Modem and the RN2903 LoRa Sub-GHz, 915 MHz North American modems. You can read about these two modems in the Across the Miles article on page 7.

    LoRa Technology Overview LoRa technology, originally developed by Semtech Corporation, utilizes a spread spectrum modulation in the Sub-GHz band to support a range of up to 15 km (rural). Its low power consump-tion enables a battery life of greater than 10 years. Offering a high network capacity, it allows developers to connect millions of wireless sensor nodes to LoRa technology gateways. LoRa technology is capable of demodulating 20 dB below noise level, significantly improving immunity to the interference when combined with integrated forward error correction. Its highest sensitivity of 148 dBm also enables extremely long-range connectivity. In comparison to 3G and 4G cellular networks, LoRa technology is far more scalable and cost effective for embedded applications.

    LoRaWAN ProtocolThe LoRaWAN protocol is a LPWAN specification intended for wireless battery-operated devices in regional, national or global networks. In comparison to mesh networks, its star topology eliminates synchronization overhead and hops, which reduces power consumption and enables multiple concurrent applications to run on the network. The LoRaWAN protocol

    LoRa technology is far more scalable and cost effective for embedded applications.

    targets key requirements of the IoT such as secure bidirectional communication, mobility and localization services to provide seamless interoperability among smart things without the need for complex local installations.

    The LoRaWAN protocol addresses a variety of applications by providing different protocol classes: Class A: Bidirectional End Devices These devices allow

    for bidirectional communications whereby each end devices uplink transmission is followed by two receive windows for acknowledgements and optional downlink transmission.

    Class B: Bidirectional End Devices with Scheduled Receive Slots In addition to the Class A receive windows, Class B devices open extra receive windows at scheduled times. (Available in future release)

    Class C: Bidirectional End Devices with Maximal Receive Slots these devices have nearly continuously open
