Freescale’s QorIQ LS1021A communications processor targets IoT gateway apps

Freescale Semiconductor has introduced an Internet of Things (IoT) gateway reference design supporting a broad array of IoT applications, including building/home management, smart cities, networked industrial service,s and other applications where performance and reliability are critical. The production-ready reference design, named the LS1021A IoT gateway, is engineered to shorten design cycles and speed time to market for OEMs. The LS1021A allows IoT service providers to replace multiple boxes with a single, low-cost unified appliance.

The LS1021A features the QorIQ LS1021A ARM-based processor, which is engineered for fanless networking applications such as IoT gateways; as well as enterprise access points and security appliances. Built on the new Layerscape system architecture, the LS1021A processor features two high-efficiency ARM Cortex-A7 cores, enhanced with error checking and correction (ECC) technology, delivering outstanding performance at a typical power of fewer than 3 W.

The IoT gateway design features dual USB 3.0 ports, a full size SATAIII port, and twin minPCIe connectors. Also incorporated are connectors for Arduino Shield modules, which allow the platform to support a variety of communication solutions offered by the Shield family of modules.

The LS1021A integrates a number of other Freescale products including the Kinetis K20 microcontroller (MCU), an audio codec, and CAN (Control Area Network) PHYs, as well as the new MC34VR500 multi-output DC-DC converter for optimized power management. The solution is also supported by a comprehensive software development kit that simplifies coding and supports a wide variety of interfaces and protocols to ensure optimal cross-vendor compatibility.

Incorporated in the reference design and specifically engineered to work with the QorIQ LS1 family of processors is Freescale’s newly introduced MC34VR500 multi-output DC-DC converter, which leverages the LS1021A processor’s specific power efficiency features. Providing higher efficiency than competing solutions, the MC34VR500 is highly integrated for optimal processor performance and reduced development time.
