Our compiler makes your code fast, efficient and highly compact. And powerful code analysis ensures its quality. The compiler and the debugger of IAR Embedded Workbench are by many considered the best in the industry.
The functional safety versions of IAR Embedded Workbench are certified according to IEC 61508, the international umbrella standard for functional safety, as well as the automotive standard ISO 26262.
Don’t worry about fighting with learning curves, issues or bugs on your own. With support from us, you’re never alone. You get help and guidance when you need it and can stay focused on your project.
Outstanding speed optimizations enable IAR Embedded Workbench to generate very fast performing code. With the shortest possible execution times it is the ultimate choice for developing low-power applications.
Recent top scores achieved using IAR Embedded Workbench:
EEMBC is a non-profit industry association for embedded microprocessor benchmarks. EEMBC CoreMark is a simple, yet sophisticated, benchmark that is designed specifically to test the functionality of a processor core. Running CoreMark produces a single-number score allowing users to make quick comparisons between processors.

General improvements and fixes.
Support for ATmega808, ATmega809, ATmega1608, ATmega1609, and AT90SCR400 has been added.
The compiler and libraries add support for the latest C language standard ISO/IEC 9899:2011.
Note: the new C library binary object interface is incompatible with earlier versions of the product.
The compiler and libraries now support the latest C++ standard ISO/IEC 14882:2014.
Note: the new C++ library binary object interface is incompatible with earlier versions of the product.
The Unicode standard for consistent encoding, representation, and handling of text is now supported. This means that you can use Unicode characters (alphabetic, numeric, symbols, emoji, etc) in the source code.
General improvements of the IDE startup time and overall performance.
The IAR C/C++ compiler for RL78 now supports stack protection. A canary value will be placed between the stack variables and the return address so that the system can detect corruption of a function return address before the function returns to that address. The compiler will use heuristic to determine whether a function needs stack protection or not. If any defined local variable has the array type or a structure type that contains a member of array type, the function will need stack protection.
The MISRA C 2004 package in C-STAT has been updated with about 20 new checks, some of which are enabled by default.
SFR header files, linker configuration files, and device description files have been added for the latest Renesas devices.
The IDE has new artwork, enhancements to window management and docking, customizable toolbars, revised Information Center, and new tutorials.
The C-SPY Symbols and Registers windows have been re-designed with new features. The Symbols window now has a filtering function and a new column displaying to which program module a certain symbol belongs. Some of the new features in the Registers window are drag-and-drop support from source code windows, detailed register tool-tip information, and improved handling of user-defined registers groups.
The IDE Project Management and Building Guide has been updated to reflect the product changes.
Improved full report generation to reduce the risk of slowing down the IAR Embedded Workbench and/or external web-browser.
The RX66T family based on Renesas third-generation 32-bit RX CPU core (RXv3) is now supported.
Renesas Smart Configurator is a standalone tool for automatically generating control programs (device driver programs) for peripheral modules in accordance with settings. It can be downloaded from Renesas home page and fully supports code generation for IAR Embedded Workbench for RX. The generated modules are incorporated via the IAR Project Connection mechanism.
The REMEDY RTOS Viewer from RoweBots is now included as a C-SPY plugin. It provides updated information on operating system objects and system state information for the UNISON RTOS.
Newly added RX65N Envision Kit examples allows you to experience firmware updating using the new dual-bank flash function of the RX65N microcontroller, graphics performance using LCDC and a 2D drawing engine, and more.
IAR Embedded Workbench can now build projects using multiple parallel processes. This can improve build performance significantly on multi-core or multiple processor computers.
By specifying a wildcard character (*) as the configuration name, it is now possible to clean/build/make all configurations defined in the project file by calling iarbuild.exe only once.
Some of the DLIB libraries delivered with the product now contain optimized variants, such as a small integer division routine for Cortex-M0, or a fast strcpy implementation for cores that support the Thumb-2 ISA. The compiler and linker will automatically select the variant that matches the optimization goal. It is possible to override this selection by using the option --use_optimized_variants. See user guide corrections for more information.
The debugger now supports the latest CMSIS-DAP standard with WinUSB transfer mode resulting in faster debug experiences when using CMSIS-DAP v2 compliant boards.
Support for new devices from Ambiq, Cypress, Microchip, NXP, Qorvo.
The IDE has new artwork, enhancements to window management and docking, customizable toolbars, revised Information Center, and new tutorials.
The compiler and libraries add support for the latest C language standard ISO/IEC 9899:2011.
The compiler and libraries now support the latest C++ standard ISO/IEC 14882:2014.
The Unicode standard for consistent encoding, representation, and handling of text is now supported. This means that you can use Unicode characters (alphabetic, numeric, symbols, emoji, etc) in the source code.
With stack usage analysis enabled, a stack usage section will be added to the linker map file with listings of the maximum stack depth for each call graph root. The analysis process can be customized to take into account such constructs as calls via function pointers and recursion. The output can optionally be generated in XML format for post-processing activities.
The IAR C/C++ compiler for RH850 now supports stack protection. A canary value will be placed between the stack variables and the return address so that the system can detect corruption of a function return address before the function returns to that address. The compiler will use heuristic to determine whether a function needs stack protection or not. If any defined local variable has the array type or a structure type that contains a member of array type, the function will need stack protection.

The Assembler User Guide and IAR C/C++ Development Guide have been updated to reflect the product changes.
The multicore implementation has been redesigned. It is now easier to setup and configure multicore debug sessions. The debugger can now more easily cope with startup and sleep scenarios where cores are inactive.
You can now select secure or non-secure setup in the project options. In previous releases this had to be done using Extra Options.
The CMSIS-Pack implementation is now based on the CMSIS-Pack Eclipse plugin from Arm.

The new features include auto completion, parameter hint, code folding, block select, block indent, bracket matching, zoom and word/paragraph navigation. The new source browser adds features like Go to Declaration and Find All References to symbols.
The new LMS used with this release introduces new features like commuter licenses, automatic license activation and support for virtual servers.
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.
It is now possible to define custom SFR's (special function registers) in C-SPY with selectable access size and type.
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.
The new Macro Quicklaunch window makes it possible to evaluate expressions and to launch C-SPY macros. The return value from the evaluated macro or expression is shown in a separate column and the user can re-trigger the evaluation at any given point.
