RX Family

CubeSuite+ and High-performance Embedded Workshop, our integrated development environments, are easy to use, scalable to match your development needs, have a proven track record, and fully support the RX family. They enable you to handle everything from coding and building to evaluation and verification.

They provide the necessary environment for all stages of the RX application development process and are backed by comprehensive support services, enabling customers to develop new systems in less time.

Ready-to-Use Starter Kits
Learn more about this product

Want to get started evaluating RX Family products right away? Renesas Starter Kits are just what you are looking for. They contain all the development environment elements needed for MCU evaluation and initial implementation. Since all of the MCU's control signals are output, the board can be connected to the system under development for easy debugging.

[ Components of Renesas Starter Kit for RX ]

• CPU board
• On-chip debugging emulator E1
• Evaluation version of C/C++ Compiler Package for RX Family (incl. Simulator)
• Evaluation version of Flash Development Toolkit (Programming software)
• High-performance Embedded Workshop　etc.

High-Performance Evaluation Boards
Evaluation and demo boards for checking RX system operation are available. They provide a way to confirm the speedy and powerful performance of the RX with your own eyes.

[ Application Notes and Sample Code ]
Free download sample code for RX

Renesas provides sample programs with documentation describing how to use microcontroller peripheral functions as well as system examples.

• A robust lineup of RX sample code is available as it has been with previous products.
• Most sample programs include source code and register definition files are also available in the source program.
• This code can contribute to significantly shortening time to market for product development.

Peripheral Driver Generator V.2

• Generates I/O drivers for RX on-chip peripheral functions without manual coding.
• Simple operation with easy-to-use GUI
• Easy-to-understand display of peripheral I/O and I/O setting status for specific pins
• Ability to view pins used and I/O setting status for specific peripheral I/O functions
• Color-coded messages for quick identification of pin conflicts

Two Types of Emulators
Two types of emulators, an affordable on-chip debugging emulator with basic functions and a full-spec emulator system with rich, high-performance debugging functions, are available. You can select and combine the emulator that best meet your development needs.

All emulator products include the integrated development environment and an emulator-debugger that runs under it.

[ E1 and E20 On-Chip Debugging Emulators ]

• Easy connection. Allows debugging of an RX MCU while mounted on the system board.
• Powered by USB bus. No dedicated power supply needed.
• Also functions as a flash programmer.
• Environmentally friendly. All materials in components and package are RoHS compliant.

E20 Debug MCU Board for Debugging that Leaves User Pins Free With an on-chip debugger, some user pins must be used for connections to the debugger. A debug MCU board, in contrast, leaves all the user pins free while enabling the full functionality of the E20. There are also high-capacity trace and real-time RAM monitoring functions that work even with MCUs that have no trace signals.

[ E100 Full-Spec Emulator ] Learn more about this product More advanced functions such as high-capacity trace, real-time profiles, and C0/C1 coverage, combined with an easy-to-use GUI. If already in use with earlier MCUs, simply change the MCU unit for compatibility with RX MCUs.
