FreeRTOSTM software platform for RX MCUs: helping to reduce system development times

Renesas FreeRTOS makes it easy to create applications using FreeRTOSTM with Firmware Integration Technology (FIT) and Smart Configurator.


  • You can use the open-source FreeRTOSTM real-time OS in developing multi-tasking applications.
  • Take advantage of the hardware by combining the middleware and device drivers we provide with the real-time OS.
  • This package allows you to start using the peripheral functions of RX MCUs at once, and can shorten times taken in considering prototypes.
  • Applications which utilize FIT can be used for all RX-series products, and can reduce the cost of developing software as you expand your product development.
