Zephyr RTOS Expands Ecosystem with Renesas and Wind River Upgrading to Platinum Membership and New Silver Members Blecon and Embeint

Schedule for Zephyr Developer Summit on August 25-27 Now Live 

SAN FRANCISCO, June 18, 2025 – Today, the Zephyr® Project announced that Renesas and Wind River have upgraded membership to Platinum as Blecon and Embeint join as Silver members. Zephyr, an open source project at the Linux Foundation that builds a secure, connected and flexible RTOS for future-proof and resource-constrained devices, is easy to deploy and manage. It is a proven RTOS ecosystem created by developers for developers.

“The growing adoption of Zephyr RTOS reflects the strength of our developer community and the importance of collaboration in building secure and safe embedded systems,” said Kate Stewart, Vice President of Dependable Embedded Systems at the Linux Foundation. “With increased industry focus on supporting Cyber Resilience Act (CRA) requirements, Zephyr is not only expanding its ecosystem but also helping developers meet emerging regulatory and security demands.”

A Strong Ecosystem

Zephyr RTOS has a growing set of software libraries that can be used across various applications and industry sectors such as Industrial IoT, wearables, machine learning and more. It is built with an emphasis on broad chipset support, security, dependability, long-term support releases and a growing open source ecosystem. Zephyr supports more than 750 boards running embedded microcontrollers from Arm and RISC-V to Tensilica, Renesas RX, ARC and x86 as single and multicore systems. The community launched the 4.1 release in March 2025, which provided product makers with a stable foundation for building future-proof embedded connected products.

Renesas, a leading global provider of microcontrollers and microprocessors, joined the Zephyr Project last year. With deep expertise in embedded processing, analog, power and connectivity, Renesas delivers complete semiconductor solutions.

"We are thrilled to announce that Renesas has upgraded to be a Platinum Member of the Zephyr Project to help make OSS-based RTOS solutions broadly accessible across industries—including the high-performance computing (HPC) space," said Aish Dubey, Vice President & General Manager of the High-Performance Computing SoC Business Division at Renesas. "Meeting today’s stringent functional safety and cybersecurity requirements demands sustainable, shared open source software assets. Renesas is committed to advancing this foundation by collaborating closely with the Zephyr leadership community to accelerate core developments."

Wind River, a global leader in delivering software for the intelligent edge, is a founding member of the Zephyr Project and has actively contributed since joining the project at launch in 2016.

“The Zephyr Project has grown impressively in its mission to harness open-source innovation for a cross-architecture RTOS,” said Paul Miller, Chief Technology Officer, Wind River. “As a Platinum member, Wind River is proud to deepen our collaboration—bringing decades of expertise in secure, safety-critical, real-time embedded systems, and recently edge AI, to help drive the project’s next phase of evolution and adoption.”

John Kikidis, Global Ecosystem Lead at Renesas, and Tony Crupi, Senior Director of Field Engineering at Wind River, will join the Governing Board with other Platinum members including Analog Devices, Antmicro, CARIAD, Google, Intel, Meta, Nordic Semiconductor, NXP, Oticon, Qualcomm Innovation Center and ZEISS.

Blecon enables physical products to connect to cloud applications using Bluetooth technology simply, securely, and without custom infrastructure.

“Zephyr’s extensive production-ready software, modern tooling, and broad hardware support make it the ideal foundation for delivering scalable, secure Bluetooth-to-cloud connectivity for IoT products”, said Donatien Garnier, Co-Founder at Blecon. “With Zephyr, our customers bring their Blecon-enabled devices to market faster and with confidence. We’re proud to support the Zephyr Project and contribute to the community that’s enabling the next generation of connected products.”

Embeint is committed to simplifying the creation of firmware powered by ML/AI for ultra-low-power LPWAN IoT devices, making it easier than ever to embed intelligence into everyday objects.

“Joining the Zephyr Project is the obvious next step in Embeint’s mission to embed intelligence into every ultra-low power IoT device,” said Phil Valencia, CEO & Co-Founder. “Achieving our vision requires building upon a platform with the flexibility, vendor-neutral support and community engagement that Zephyr provides. Combined with our Infuse-IoT SDK, ultra-low power IoT solution providers can spend their time on breakthrough features — not low-level firmware drivers, communications stacks, and cloud services. We are excited to continue contributing to and promoting the Zephyr ecosystem as official members.”

These new members join Ac6, Alif Semiconductor, Arduino, Arm, Baumer, BayLibre, Blues, Doulos, Ezurio, Golioth, Honday, Hubble Network, IAR, Infineon, inovex, IRNAS, Linaro, Memfault, Microchip Technology, MicroEJ, Percepio, Qt Group, Silicon Labs, STMicroelectronics, Synopsys and Texas Instruments as Silver members.
