Azure RTOS Components Integrated into Renesas RA Flexible Software Package, Renesas Synergy Software Platform, and Easily Accessible via Renesas RX’s Smart Configurator

June 15, 2021

TOKYO, Japan ― Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, today announced that customers designing with all mainstream Renesas 32-bit MCU families now have access to Microsoft Azure Real-Time Operating System (RTOS) embedded development suite, including its powerful Azure IoT middleware. Azure RTOS is integrated and available out-of-box in the recently released Flexible Software Package (FSP) version 3.0 for the Renesas’ RA Family MCUs, and the Synergy Software Package (SSP) version 2.0 for Synergy MCUs. Azure RTOS support for Renesas’ RX Family is provided through the e2 studio integrated development environment.

Microsoft Azure RTOS  includes Azure RTOS ThreadX, an advanced real-time operating system designed specifically for deeply embedded applications. Among the multiple benefits it provides are real-time multithreading, inter-thread communication and synchronization, and memory management. Azure RTOS ThreadX offers advanced features, including picokernel architecture, preemption-threshold, event chaining, and a rich set of system services.

“We have reached a critical milestone in our collaboration with Microsoft and are excited to be able to offer our customers access to this industry-leading RTOS platform across our 32-bit MCU lines,” said Roger Wendelken, Senior Vice President in Renesas’ IoT and Infrastructure Business Unit. “We’ve worked hard to ensure this integration enables a seamless developer experience with access to pre-integrated project templates and smart configurators. This integration leverages unique capabilities of our Secure Crypto Engine, enabling a highly robust security foundation.”

“Empowering developers is one of the most effective ways for organizations to unlock innovation and increase time to value” said Sam George, Corporate Vice President, Azure IoT at Microsoft Corp. “This is the ambition of the integration of Azure RTOS with Renesas’ FSP and SSP software packages—this step forward marries Renesas’ leading development experience with the secure, scalable, and open edge-to-cloud IoT capabilities of our Azure IoT platform. There’s never been a better time to build on Renesas’ 32-bit family of MCUs.” 

In addition to Azure RTOS ThreadX, designers of RA, RX and Synergy applications will have access to the following middleware stacks:

  • Azure RTOS FileX high-performance File Allocation Table (FAT)-compatible file system
  • Azure RTOS GUIX embedded graphical user interface (GUI) application design environment
  • Azure RTOS TraceX Windows-based analysis tool
  • Azure RTOS NetX Duo industrial-grade dual IPv4 and IPv6 TCP/IP network stack
  • Azure RTOS USBX high performance USB host and embedded stack

Later in 2021, Renesas will release cloud development platforms providing developers with a comprehensive framework to securely connect to and leverage the power of Azure IoT. These cloud platforms with feature a host of different connectivity options out-of-box, including Bluetooth®, Cellular, Ultra-wideband, and Wi-Fi 6/6e. These Azure Certified kits will be available through the Azure Device Catalog.

About Renesas’ Flexible Software Package

The easy-to-use Flexible Software Package (FSP), which includes a best-in-class HAL driver, supports Renesas’ high-performance RA Family MCUs based on 32-bit Arm® Cortex®-M processors. The FSP uses a GUI to simplify and dramatically accelerate the development process, while also making it easy for customers to transition from an original 8/16-bit MCU design. A video previewing the FSP developer experience with Azure RTOS is available at https://aka.ms/MicrosoftAzureRTOS/RenesasFSP/Video.

About Renesas’ Synergy Software Package

The Synergy Software Package (SSP) is a tightly integrated, optimized, and qualified suite of software that scales with end-product complexity and simplifies complex system-level services. SSP components are tightly integrated, optimized, tested, documented, and maintained by Renesas. A layered architecture enables developers to write their application with the Application Framework using common APIs, or by directly connecting to the device driver level as needed.
