Renesas Electronics America, Intrinsic ID, Medium One debut sensor-to-cloud platform to simplify secure IoT development

Semiconductor company Renesas Electronics America; Intrinsic ID, a digital authentication company and inventor of SRAM Physical Unclonable Function (SRAM PUF); and Medium One, an Internet of Things (IoT) Data Intelligence company, announced Monday their collaboration on the RX231 Wi-Fi Cloud Connectivity Kit, which integrates Renesas RX231 MCUs, Intrinsic ID IoT authentication, and Medium One’s cloud services and workflows.

The Renesas RX231 Group of MCUs provides the framework of the new RX231 Wi-Fi Cloud Connectivity Kit. Featuring a 32-bit RXv2 CPU core with improved DSP/FPU and low-power consumption technology, RX231 MCUs allow designers to realize extreme power efficiency for their IoT applications.

The kit comes pre-programmed with an IoT Authentication demo that provides users with firsthand experience at establishing a root of trust for their systems. The kit uses state-of-the-art Intrinsic ID PUF technology working in conjunction with hardware-based Trusted Secure IP and the security functions available in the Renesas RX231 MCUs and powered by Medium One’s cloud-based computing and data intelligence platform.

The RX231 Wi-Fi Cloud Connectivity Kit also comes pre-programmed with a Smart Machine demo that allows developers to easily set up a cloud platform with dashboards and analytics for streaming real-time data to their account. The combination of Renesas’ RX231 MCU, Intrinsic ID’s IoT Authentication, and Medium One’s Smart Machine demo with accelerometer deliver a pre-configured platform that is easy to use and dramatically accelerates IoT development cycles.

Based on Renesas’ RX231 line of 32-bit microcontrollers (MCUs), the new evaluation kit incorporates Intrinsic ID’s “root-of-trust” SRAM PUF technology and Medium One’s cloud services and IoT workflows. This combination provides developers a quick and easy method to evaluate the IoT capabilities of RX231 MCUs and on-chip peripherals with an out-of-the-box platform for home appliances, industrial automation, and medical applications.

“Security and connectivity go hand in hand, and as more connected devices come online, developers are looking for the holy grail of embedded design – secure, authenticated Wi-Fi connectivity for their product platforms that is easy to implement,” said Semir Haddad, Director of Marketing, MCU and MPU Product Solutions, Renesas Electronics America. “Working together, Renesas, Medium One, and Intrinsic ID are bridging the complexity gap with a cost-effective board-to-cloud platform with integrated root-of-trust IoT authentication that enables developers to rapidly build out their IoT platforms with confidence.”

“Embedded and cloud developers who have traditionally worked in different environments with different platforms and tools now have the added complexity of operating in each other’s fields,” said David Thai, President and CEO of Medium One. “The new RX231 Wi-Fi Connectivity Kit makes that task easier, bringing the combined capabilities of Renesas’ best-in-class hardware, Medium One’s data intelligence software, and Intrinsic ID’s IoT authentication capability to speed access to intelligent data analytics and implementation.”

“Working with industry leaders Renesas and Medium One, we have delivered a board-to-cloud developer kit, complete with working sample code for SRAM-PUF-based authentication,” said Pim Tuyls, CEO of Intrinsic ID. “Using the new RX231 Wi-Fi Kit, IoT developers can bypass the often lengthy parts assembly and test environment building processes, and immediately dive into development, speeding up time to market for their secure IoT solutions.”

The RX231 Wi-Fi Connectivity Kit, part number YWIRELESS-RX231, is available now through Renesas and can be ordered directly from, and is priced at US$59 suggested resale.
