Notes

  1. The difference between the standard and professional editions, Refer to here for details.
  2. The C compiler package for RL78 and 78K families (CA78K0R) is a separate and earlier product.
  3. We currently support only the following products with both floating and annual licenses.
    • C Compiler Package for RL78 Family (CC-RL) V1.01.00 or later
  4. The e² studio or CS+ must be installed separately.
  5. 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 Compiler without IDE, it's possible to download CS+ from a web, install, register a bought license key and use.)
  6. CS+ is not promoted in America and Europe. Please contact your regional marketing/sales team for information.

Upgrading (Editions)

This license upgrades the version of the compiler from standard edition V1 to professional edition V1. 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.
