The Renesas Synergy™ Software Package (SSP), part of the Renesas Synergy Platform, is a complete integrated software package designed to provide easy-to-use, scalable, high-quality software for embedded system design. Using the Synergy Software Platform will reduce time to market by providing a completely integrated and qualified embedded software platform comprising an industry-leading, completely optimized, and hardened Real-time Operating System (RTOS), middleware, communication stacks, function libraries, application framework, and hardware abstracted low-level device drivers.


  • Application framework for abstraction and code re-use
  • ThreadX®, a proven commercial RTOS
  • X-Ware™, NetX Duo™, NetX Secure™, USBX™, GUIX™, FileX®
  • Flexible layered architecture
  • Developed under the IEC/ISO 12207 Software Life Cycle process
  • Qualified to operate as specified by the SSP datasheet
  • Robust common API across Synergy MCUs

*Important Notice:
 On November 21, 2023, Microsoft announced that they have decided to contribute Azure RTOS to Open Source under the stewardship of the Eclipse foundation and Azure RTOS becomes Eclipse ThreadX.

For detailed information, please refer to the announcement titled at Microsoft Contributes Azure RTOS to Open Source.

The support strategy scheme for Eclipse ThreadX will be determined and communicated at a later date.

Microsoft will discontinue the Azure RTOS and Azure RTOS Middleware. It’s important to note that updates for Azure RTOS on this hardware will no longer be provided.

Synergy Software Package (SSP) Components

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. Learn the functions of each SSP component here.

Software Quality

Renesas has established a Software Quality Assurance (SQA) process for the SSP to cover the necessary Testing and Software Development Life Cycle (SDLC).

SSP quality is tracked and measured using combinations of unit, functional, integration, performance, regression, dynamic, and static analysis tests. To ensure high quality, production grade Software, SSP is developed and tested to ensure adherence with the four quality metrices

  • Meet coding standards
  • Maintain low code complexity
  • Build cleanly
  • Comprehensive module and system level testing

Synergy™ Standalone Configurator (SSC)

The Synergy Standalone Configurator (SSC) is an Eclipse Rich Client Platform application that duplicates the functions of the Synergy Project Generator and Project Editor tools in the e2 studio ISDE, bringing graphical component configuration to the IAR Embedded Workbench® for Renesas Synergy users.

The Synergy Project Generator provides a guided setup process that includes selection of the device, debugger and compiler options. A pre-configured project with necessary support files, such as device-specific headers, is generated and ready for build and debug.

The Synergy Project Editor allows users to set up the clock tree and configure I/O pins. It contains the Synergy Software Package (SSP) Module Configurator that allows the addition of SSP modules to individual RTOS threads, messaging framework setup, and interrupt enablement.

The image below shows how the IAR Embedded Workbench for Renesas Synergy, SSC and SSP work together to create Synergy projects.
