Getting Started

Development is supported by the Renesas e2 studio IDE and the CC-RX compiler. Engineers can utilize the RX65N Cloud Kit or the RSK+ (Renesas Starter Kit) for rapid prototyping of Ethernet and USB applications. Renesas also provides the FIT (Firmware Integration Technology) ecosystem to simplify driver integration for the 144-pin LFQFP package.
