IoT gateway reference design

October 06, 2014 // By Julien Happich
Freescale Semiconductor has launched a versatile and reliable Internet of Things gateway reference design supporting a broad array of IoT applications including building/home management, smart cities and networked industrial services.

Designed in collaboration with Freescale manufacturing partner TechNexion, the reference design leverages the proven security, class-leading efficiency, advanced virtualization support and rich set of peripherals of the award-winning QorIQ LS1021A processor, which has reached volume sampling and is now available for ordering.

The LS1021A IoT gateway is engineered to shorten design cycles and speed time to market for OEMs, it allows IoT service providers to replace multiple boxes with a single, low-cost unified appliance.

At the heart of the Freescale gateway lies the QorIQ LS1021A ARM-based processor, which is engineered for fanless, enterprise and consumer 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 a wide assortment of high speed and serial-based connectors, including dual USB 3.0 ports, a full size SATAIII port, and twin minPCIe connectors; all in a compact, highly secure design. 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 reference design also 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.

A comprehensive software development kit simplifies coding and supports a wide variety of interfaces and protocols to ensure optimal cross-vendor compatibility.
