The Prepaid by Renesas Guiliani Lite license for Guiliani Evalkits

You can obtain an additional Guiliani-Lite production license key from TES. This license is free of charge for Renesas RZ/A users. With this license you are able to produce state-of-the-art HMI applications for production use. The Lite version of Guiliani is fully featured and only has small limitations on usable resources (number of images, dialogs, fonts, etc) and hardware acceleration. To get the Prepaid by Renesas Guiliani-Lite license, please refer to TES Guiliani.


  • By linking with the intuitive configurator of "e2 studio", which is a software integrated development environment, and the code generation function, it is possible to proceed with real-time system development efficiently and quickly.
  • Support both RTOS applications and bare metal applications.
