IAR Embedded Workbench for AVR32

The complete development toolchain IAR Embedded Workbench for AVR32 provides one toolbox in one view, giving you one uninterrupted workflow.

User-Friendly IDE

Integrated development environment with project management tools and editor including linker and library tools, example projects and code templates for AVR32.

Powerful Build Tools

The IAR C/C++ Compiler is a highly optimizing C and C++ compiler for AVR32. It offers configuration files for all AVR32 devices, relocating AVR32 assembler and run-time libraries. In addition, it includes parallel data path recombination to utilize SIMD instructions and Atmel AVR32 ABI compliant.

Comprehensive Debugger

The C-SPY Debugger provides a AVR32 simulator, support for RTOS-aware debugging on hardware and AVR32 JTAGICE mkll, JTAGICE3 and AVR ONE! emulator support.

Integrated Code Analysis

IAR Embedded Workbench for AVR32 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 their tools with new features, new device support and extended capabilities.

Latest Version: 4.30


The add-on product C-STAT for static analysis is now supported. C-STAT features innovative static analysis that can detect defects, bugs, and security vulnerabilities as defined by CERT and the Common Weakness Enumeration, as well as help keeping code compliant to coding standards like MISRA C:2012/2004 or MISRA C++:2008.

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 enable parallel build, select Tools>Options>Project>Enable parallel build.

Stack Usage Analysis

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.

Latest Version: 4.20

New Text Editor and Source Browser

A new text editor and source browser are introduced in this version. 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.

New License Management System

The new LMS used with this release introduces new features like commuter licenses, automatic license activation, and support for virtual servers. It is easier to administrate and a single installer concept enables easy transfer between all variants of IAR Embedded Workbench for a certain product by a license upgrade.

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.

Call Graph Window

The 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.

Macro Quicklaunch Window

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.

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.

Live Watch

The Live Watch window repeatedly samples and displays the values of expressions while your application is executing.

Compiler Optimizations

Improved optimizations will give significantly faster execution of target code and smaller code size.

Extended Inline Assembler

The inline assembler has been extended with the possibility to take input arguments, give return values, and read or write to C symbols. The syntax is similar to the syntax used in GNU GCC.

New Devices

ATUC128L3U, ATUC128L4U, ATUC256L3U, ATUC256L4U, ATUC64L3U, and ATUC64L4U
