01
User-friendly IDE
Integrated development environment with project management tools and editor. Included is automatic checking of MISRA C rules (MISRA-C:2004), configuration files for all 78K0, 78K0S and 78K0R devices, linker and library tools as well as example projects and code templates.
02
Powerful build tools
The IAR C/C++ Compiler is a highly optimizing C and C++ compiler for 78K. Included is also run-time libraries and a relocating 78K assembler.
03
Comprehensive debugger
The C-SPY Debugger comes with a 78K simulator, support for RTOS-aware debugging on hardware and emulator debugging support.
04
On-demand training included
When you buy a license of IAR Embedded Workbench for Renesas 78K, you get access to free training courses through our IAR Academy on Demand offering.
Latest releases
Version 4.81
-
Parallel build
IAR Embedded Workbench can now build projects using multiple parallel processes. This can improve build performance significantly on multi-core or multiple processor computers. To control parallel build, choose Tools>Options>Project>Enable parallel build. -
Sampled Graphs in C-SPY
It is now possible to specify variables for which you want to collect data samples. You can view the sampled data either in table format in the Data Sample window or as graphs in the Sampled Graphs window.
Custom SFR window
It is now possible to define custom SFR's (special function registers) in C-SPY with selectable access size and type.
-
Saving C-SPY Watch window content
In the C-SPY Watch window family, you can now choose Save All to File from the context menu to save the contents of the current window to a text file. -
New windows for C-SPY macros
Three new C-SPY windows have been added to easier manage C-SPY macros. The Macro Registration window controls which macro files are loaded and the Debugger Macros window shows a list of all macros available in the debugger. The Macro Quicklaunch window makes it possible to evaluate expressions and to launch C-SPY macros. -
Project connection
Files or file packages generated by external code generation tools can be imported and IAR Embedded Workbench automatically detects changes in the generated file set. This enables automated integration with for example device configuration tools. -
External analyzers
A flexible mechanism to invoke external analyzers for project files. This is typically used as an interface to static analysis tools like PC-lint. -
Custom argument variables
Custom argument variables can be used in the IAR Embedded Workbench IDE whenever there is a need for a macro-like expansion that depends on the current context. This could for example be in arguments to an external build tool. -
Call Graph window
A new Call Graph window has been added. It is browsable and displays all calls made to and from each function from any source file in the active project. -
Save as for project workspaces
It is now possible in the IDE to save a project workspace with a new name.

Languages and standards
-
The IAR C/C++ compilers offer different dialects of the C and C++ programming languages, as well as different extensions specific for embedded programming (please note that not all language standards are supported for all target implementations). The compiler can be instructed to disable extensions for strict conformance to the standards.
A wide range of industry-standard debug and image formats compatible with most popular debuggers and emulators are supported. This includes ELF/DWARF where applicable.
ISO/ANSI C/C++ Compliance
The IAR C/C++ compilers adhere to a freestanding implementation of the following C programming language standards:
- INCITS/ISO/IEC 9899:2018, known as C18 (Latest version only).
- The compiler supports all C++17 features. The C++ library supports C++14 with no C++17 additions. (Latest version only).
- ISO/IEC 14882:2015, known as C++14
- INCITS/ISO/IEC 9899:2012, known as C11
- ANSI X3.159-1989, known as C89
The ISO/ANSI C/C++ Compliance level varies between the different compilers. For complete information, please refer to the IAR C/C++ Compiler user documentation in your chosen product.
IEEE 754 standard
IAR Embedded Workbench supports the IEEE 754 standard for floating-point arithmetic.
MISRA C
MISRA C is a software development standard for the C programming language developed by MISRA, The Motor Industry Software Reliability Association. Its aims are to facilitate code safety, portability and reliability in the context of embedded systems, specifically those systems programmed in ISO C.
The first edition of the MISRA C standard, "Guidelines for the use of the C language in vehicle based software", was produced in 1998. In 2004, a second edition was produced with many substantial changes to the guidelines, including a complete renumbering of the rules. Additionally MISRA C:2012 with extended support and MISRA C++:2008 for identifying unsafe code constructs in the C++ standard have also been added to the standards.
IAR Embedded Workbench features an add-on product C-STAT so you can check compliance with rules as defined by MISRA C:2004, MISRA C++:2008 and MISRA C:2012.
Test validation
We use the following commercial test suites to test conformance of our tools to the standards:
- Plum Hall Validation test suite for ISO/IEC C conformance
- Perennial EC++ Validation Suite for C++ conformance
- Dinkum C++ Proofer to test how our libraries conform to the C and C++ standard as well as test our STL implementation against the C++ standard.
In addition to the commercial suites, we use several in-house test suites for testing new features, regression testing, corrected errors, etc.
