Industrial IoT Reference Design Supports Arduino and ARM mbed Platforms


New Industrial IoT Reference Design from Maxim Integrated allows designers to rapidly prototype industrial IoT solutions while addressing the genuine issues of data security and authentication. The MAXREFDES143# provides protection against counterfeit sensor data, guaranteeing its authenticity and integrity along the entire data chain, from transducer to the cloud, according to Maxim.

“The reference design is a powerful, much-needed tool for addressing the genuine issues of data security and authentication for Industrial IoT installations,” said Scott Jones, Executive Director, Embedded Security, Maxim Integrated. “The reference design combines the shield and sensor node to offer a solution with a high level of security and minimal development start-up effort, and with low system-overhead burden.”

The reference design offers an Arduino-compatible hardware interface and ARM mbed libraries support to simplify development of secure, uncorrupted, and authenticated sensor-to-web data. It is ideal for analog sensor node and data authentication in factory automation and industrial processing applications.

The design features a two-stage hierarchical architecture consisting of a shield that communicates to a web server, and a protected sensor node for data acquisition and authentication. The shield includes a Wi-Fi module, a DS2465 secure coprocessor for offloading SHA-256 cryptographic computation, 1-Wire and I2C interfaces, user-interface LCD, LEDs, and pushbuttons, and alarm and logging functions. The sensor node contains a DS28E15 secure authenticator, DS7505 temperature sensor, and MAX44009 light sensor.

“Enabling robust security and data integrity is critical to the continued adoption of IoT solutions,” said Michael Horne, Vice President of Marketing and Sales, IoT Business, ARM. “The MAXREFDES143# simplifies testing with ARM mbed-compatible development boards, allowing designers to rapidly develop resilient industrial IoT platforms.
