Notes

  1. The difference between the standard and professional editions, Refer to here for details.
  2. A license key is common for both distribution format "with" and "without" IDE. In other words, a license key can be applicable for any or both of CS+ and e² studio. (e.g.: When buying C/C++ Compiler without IDE, it's possible to download CS+ from a web, install, register a bought license key and use.)
  3. We currently support only the following products with both floating and annual licenses.
    • C/C++ Compiler Package for RX Family (CC-RX) V2.03.00 or later
  4. The e² studio or CS+ must be installed separately.
  5. CS+ is not promoted in America and Europe. Please contact your regional marketing/sales team for information.

This license upgrades the version of the compiler from standard edition V3 to professional edition V3. Note that this form of upgrade (of the edition) is only for node-locked licenses; it will not apply to floating licenses and annual licenses.

When ordering, please contact your local Renesas Electronics marketing office or distributor.

Available Kit and Related Services

IEC61508 Certification Kit for RX Compilers

This kit supports the certification of development tools which are required for the IEC 61508 functional safety standard. Writing software that must satisfy functional safety standards requires verification of the compiler generating code which is safe in the stipulated ways. Renesas offers a C compiler that is certified for functional safety to IEC 61508 Safety Integrity Level (SIL) 3.

Compiler Qualification (Service to Support Functional Safety)

For customers who are using a compiler for Renesas devices, we offer a support service for the qualification of confidence that development tools meet the requirements of ISO 26262, Road Vehicles Functional Safety. This service incurs a charge.

Compiler Maintenance Service (Agreement for Maintenance Service for a Specified Compiler Version)

Renesas offers a maintenance service for a specific compiler version for customers who are using the compiler over the long term. This service incurs a charge.

Assistance with Compiler Migration

The IDEs from Renesas (such as the e² studio and CS+) allow for the porting of projects between IDEs to facilitate the reuse of existing resources. Refer to the guidance page of migration when changing your compiler after changing your development environment. The guidance page describes precautions that must be taken when changing compilers, such as differences in options and in extended language specifications.

Since this information supports the compiler language specifications of existing products, it eases the porting of programs from existing mid-range Renesas products such as those of the M16C, H8S, or H8SX families. The superior optimization of the new compilers will make your object code even more compact and run more efficiently on RX devices.

Switching from Evaluation Editions to Commercial Editions

To upgrade the evaluation edition of a compiler to the commercial edition, enter the license key printed on a purchased compiler package to the e² studio or CS+ IDE (while installing or after having installed the IDE). This lifts the restrictions on functionality of the compiler for the target MCUs, upgrading the compiler to the commercial edition. For details, see the following manuals.

Upgrading Versions of Compilers

The compiler licenses differ per version. For example, V2.**.** and V3.**.** have different licenses since they have different version numbers.

Upgrading of versions of compilers is for a fee and requires a separate license key. If you do not have the license key for a new version, upgrading makes your compiler the free evaluation edition of the new version, even if you have the license key for an old version. You can still use the old version as the commercial edition in such cases.

Updating a Compiler

Update your compiler with every revision so that you are using the latest one. Refer to Tool News for details of how to update compilers.

Information on updating (Tool News) >>

For customers who are using the e² studio
Download the installer of the latest compiler and run the installation. Latest installer >>
For customers who are using CS+
Start the Update Manager to run the update.

Updating from revision to revision of the same version is free, while updating from version to version incurs a charge, as shown in the examples below.

  • Revision update: Free of charge; e.g. V3.01.00 to V3.02.00
  • Version update: Updating incurs a charge; e.g. V2.08.00 to V3.01.00 (commercial edition)

Updating the Set of Supported Devices

For customers who are using the e² studio
Simply use the latest version of the e² studio
