  • The compiler applies our latest optimization techniques to the generation of compact code (up to a 10-percent (Note2) improvement over the CA78K0R).
  • Easy optimization settings and many optimization features

Cooperated with RL78 MCU architecture

  • Interrupt processing routines can be written in the C language (up to a six-fold (Note2) improvement in interrupt response performance over code compiled by the CA78K0R compiler).
  • Provides intrinsic functions

An MISRA C rule checker supports the description of high-quality program (Note3)

  • Supports automatic checking of C source code based on the MISRA-C: 2004/2012 rules as compiler options
  • About MISRA C, refer to here.

Assistance in Porting Files to the CC-RL from the CA78K0R, refer to here.

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.
