Complete set of development tools with leading optimization technology for creating powerful automotive applications based on RH850.

User-Friendly IDE

One Integrated Development Environment with project management tools and editor. Included is configuration files for all RH850 devices, example projects and code templates, linker and library tools and Renesas Smart Configurator.

Powerful Build Tools

Included is a hHighly optimizing C and C++ compiler for RH850, run-time libraries, relocating RH850 assembler. It is also compliant with Renesas RH850 ABI and the ISO/IEC 9899:2011 and ISO/IEC 14882:2014 standards.

Comprehensive Debugger

The C-SPY Debugger comes with a RH850 simulator, support for RTOS-aware debugging on hardware, emulator debugger support, multicore debugging support for symmetric multicore processing (SMP) and stack usage analysis.

Integrated Code Analysis

IAR Embedded Workbench for RH850 provides integrated static code analysis through the add-on product C-STAT, ensuring code quality as well as proving alignment with standards such as MISRA C:2012.

Latest Releases

IAR Systems are constantly updating and refining our tools with new features, new device support and extended capabilities.

Latest Version: 2.21

Support for position-independent code and ready-only data (ROPI)

When using position-independent code and ROPI, the compiler in IAR Embedded Workbench for RH850 will generate code that uses PC-relative references for addressing code and read-only data.

Updated Device Support

The device support files have been updated to the most recent version from Renesas.

Updated User Documentation

The C/C++ Development Guide, and IDE Project Management and Building Guide have been updated to reflect the product changes.

Latest Version: 2.20

  • Updated Device Support

Support has been added for the RH850/U2A, C1x, D1x, E1x and E2x series of microcontrollers.

  • C18 Support

The default Standard C is now C18 (ISO/IEC 9899:2018).

  • C++17 Support

The compiler now supports almost all C++17 features. The C++ library supports C++14 with no C++17 additions.

  • Extended Coverage of CERT C

The static analysis tool C-STAT has extended its coverage of the SEI CERT C Coding Standard. The SEI CERT C Coding Standard’s goal is to provide rules for developing safe, reliable and secure systems in the C programming language, with support for C11 constructs.

  • Improved Source Browser

The following improvements have been made to the Source Browser:

  • The source browser data is generated faster as it is now running as a separate thread.
  • New Source Browser Log window.
  • Status indicator in the status bar.
  • Enhanced feedback in case source browsing data cannot be generated.
  • Documentation Comments Support in the Editor

The editor can distinguish comments that start with /*, /!, /// or //! as Documentation Comments. Inside a Documentation Comment, the editor can recognize keywords that begin with \ or @. If the keyword is recognized as a doxygen keyword, the Documentation Comment will appear in tooltips and parameter hints for variables and functions. See IAR Embedded Workbench IDE Project Management and Building Guide for more information.
