MicroEJ for Renesas

MicroEJ® is a scalable solution to prototype, develop, and test software applications for embedded systems designed with Renesas 32-bit processors. The MicroEJ embedded platform concept drastically lowers costs of building applications, using software technologies inherited from the Java technology: Object Oriented Programming and Virtualization. It enables developers to create portable and scalable applications, easy to maintain and reliable while keeping small memory footprints and low power consumption.

MicroEJ for Renesas RX and RZ MCU families

As a result of the strong collaboration between Renesas, the MicroEJ Software Development Kit (SDK) supports the RX family of products based on the Renesas RX proprietary core, as well as the Renesas RZ series powered by the ARM Cortex A9. The MicroEJ solution is ready to be evaluated with the YLCDRX63N board (480×272 LCD display, RX63N@100MHz) and the RZ/A1H board (ARM Cortex-A9 @400MHz – 800×400 WVGA display). MicroEJ includes everything required to start a HMI development on these boards and run a Java application in less than a few hours.
