The Renesas Demonstration Kit (RDK) for RX63N is an evaluation and demonstration tool for Renesas RX63N microcontrollers. The goal is to provide the user with a powerful debug and demonstration platform targeted at common applications. The board also provides a useful platform for evaluating the Renesas suite of development tools for coding and debugging, using the High-performance Embedded Workshop (HEW) IDE as well as programming the device using the on-board SEGGER J-Link JTAG debugger.

The Renesas Demonstration Kit for RX63N is also the hardware platform that is included in a special RX63N-specific edition of Micrium's book on the µC/OS-III Real Time Kernel. The book and board combo targets serious programmers and college students who need to understand and create programs based on the timesaving features of a real-time kernel. Part I of the text covers the internals of the new µC/OS-III real-time kernel. The emphasis is on the internals, features, API calls, and where and how to use an RTOS, all presented in a clear and useful way, and accompanied by a wealth of diagrams. Part II provides specific examples for using µC/OS-III on the new Renesas RX63N microcontroller.
