What is Flash Development Toolkit?

The Renesas Flash Development Toolkit is a tool that allows you to build application for Renesas flash type microcomputers. The 740 Family, H8SX Family, H8 Family, H8S Family, RX Family, R8C Family, M16C Family and SuperH RISC Engine Family are some of the Renesas microcomputing devices for which it was particularly built.

The toolkit is often used in conjunction with the High-performance Embedded Workshop, which allows users working on embedded programs for the microcomputing unit in question to develop in a single environment. The program’s usage of a straightforward visual-interaction-focused interface makes it an easy application for new developers to learn as well.

Users can also keep track of the progress by using the inbuilt message logging capability. Because of the option for field programming all projects may be exported, and any errors can be recognized and corrected before they go through the appropriate function. Multiple checksums are also available. The toolkit is no longer being updated by its creator, however users of the application continue to get technical help from the firm.

Key of Features:

  • Useful messaging log to show the programming progress.
  • Field programming function to export the project easily.
  • Access right function to prevent the errors before they occur.
  • Build function to combine more than one file.
  • Multiple checksum which is useful for programming and file discrimination.


  • We have released v.4.09 Release 03 of the Flash Development Toolkit. The new release supports Windows 10 and 8.1.
    However, the addition of new functionality and supported MCUs has been discontinued from V.4.09 Release 02.
    • V.4.09 Release03 supports Windows 10, 8.1 and 7.
    • V.4.09 Release02 supports Windows 7, Vista and XP.
  • Free-of-charge update from previous version before Ver.3 of Flash Development Toolkit to Ver.4 is not available. Please purchase the revised product if necessary.

The Flash Development Toolkit has three user-friendly GUIs which are available to choose the one depending on the purpose of use.

With Generating Project

Main Window

Thank to its project management function, this window permits data management for a system comprised of multiple microcomputers and data management in each development phase to be exercised efficiently. Furthermore, its data editing function permits you to edit parameters easily. This window provides you the convenient environment during a development stage.

Simple Interface Window

You can use this window by calling it from the main window after creating a project. By using the project management function. You can write data for multiple projects to your MCU easily. This window provides you the convenient environment when it is used during a mass-production stage or when there are multiple data and devices to manage.

Without Generating Project

Basic Window

You can use this window by starting it directly. This window permits you to write data to your MCU easily without having to create a project. This window provides you the convenient environment when used during a mass-production stage or when there are one data and device to manage.
