Features

ANSI-compliant
  • Support C89, C99 (Note1) of ANSI
Superior optimization
  • The compiler applies our latest optimization techniques to generate code that has excellent performance in execution (up to a three-fold (Note2) improvement in execution performance over code compiled by the CA78K0R compiler, our previous product).
  • 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 variable length array type, complex type, and some standard library functions of the C99 standard are not supported.
  2. These values were measured for programs held by Renesas.
  3. Professional edition only

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.
