Settings in a GUI and then one click of the mouse button is a simple way to produce initial settings for your microcontroller, and greatly reduces working hours for development.

The code generator plug-in can automatically generate control programs for peripheral modules (device driver programs). By generating needed source code in accordance with user settings, the plug-in shortens development terms and dramatically reduces costs.

The CS+ and e² studio integrated development environments from Renesas include the code generator plug-in. However, the situations to which the tool can respond depend on the microcontroller and integrated development environment, so refer to "Microcontrollers for Code Generation" below for details of product compatibility.

The code generator plug-in is a tool that you can install and use free of charge. Its operation is not guaranteed, although we have carefully evaluated the generated code. The user assumes all responsibility related to installing and using this tool.


We have revised the code generator plug-in for the RL78.

A Note to Users of the Code Generator Plug-in for RX

From now on, we do not intend to add or modify the support for devices by the Code Generator Plug-in for RX. Please refer to the release notes for instructions on using the Code Generator Plug-in for RX.

Accordingly, although we will continue to support the Code Generator Plug-in for RX users, we recommend that you consider migrating to the Smart Configurator from the Code Generator Plug-in.

Release Information

CS+ Code Generator:

Details of upgrade (See Tool News)

Operating Environment


  • Simple operation of all processes through an easy-to-understand GUI
  • Handles checking for cases where multiple peripheral modules are contending for the same pins
  • An API provides functions to make the peripheral functions operate
  • Since this tool is included in the CS+ and e² studio integrated development environments from Renesas, all processes from editing and building code to debugging can be smoothly executed from the same integrated environment
