Reference Design For An IoT Gateway

The LS1021A- IoT gateway reference design enables you to deploy new IoT services at your home or workplace with ease.

Do you want to introduce automation to your home, office, or factory? Do you want to integrate sensors and other devices which can ease your job and keep the environment more cozy, do you want to utilize the internet (IoT) to make your space more intelligent. Then an IoT gateway is something you’ll need so that you can connect different IoT devices from different manufacturers working on a different protocol. To simplify designing the IoT gateway, NXP has release a reference design which offers support for different connectivity protocols and a secure channel for IoT communication for the end user.

The LS1021A is an affordable reference design for an IoT gateway. The reference design is based on the QorIQ LS1021A processor (LS1021A-IOT-B), the reference design combines standards-based, open-source software together with a feature-rich IoT gateway design, to establish a common, open framework for secure IoT service delivery and management. The LS1021A-IOT-B processor employed in the design adds a wide array of high-speed connectivity and low speed serial interfaces. The IoT gateway design establishes a common, open framework for secure IoT service delivery and management.

The above reference design can help with protocol translation as the IoT gateway can translate between different protocols to ensure that devices can communicate with each other. This allows for interoperability between devices from different manufacturers and enables devices to work together in a coordinated way. Moreover, it improves security as it offers secure boot, Trust Architecture and tamper detection for both standby and active power modes.

This device is ideally suited to power system solutions with unique programmable multiple DC/DC and LDO outputs. In addition to its high efficiency and high level of integration, the LS1021A-IoT gateway design offers HDMI, SATA3 and USB3 connectors as well as a complete Linux software developers package
