IAR Systems develops C and C++ compilers, debuggers, and other tools for developing and debugging firmware for 8-, 16-, and 32-bit processors. The company started out in the 8-bit market, but moved into the expanding 32-bit market, especially the market for 32-bit microcontrollers.

IAR Systems is headquartered in Uppsala, Sweden and has more than 200 employees globally. The company operates with subsidiaries in Germany, France, Japan, South Korea, China, United States and United Kingdom and reaches rest of the world through distributors. IAR systems is a subsidiary of IAR Systems Group.



  • IAR Embedded Workbench — a development environment that includes a C/C++ compiler, code analysis tools C-STAT and C-RUN, security tools C-Trust and Embedded Trust and debugging and trace probes
  • Functional Safety Certification option
  • Visual State — a design tool for developing event-driven programming systems based on the state machine paradigm. IAR Visual State presents the developer with the state machine subset of UML for C/C++ code generation. By restricting the design capabilities to state machines it is possible to employ formal model checking to find and flag unwanted properties like state dead-ends and unreachable parts of the design. It is not a full UML editor.
  • IAR KickStart Kit — a series of software and hardware evaluation environments based on various microcontrollers.

IAR Embedded WorkbenchEdit

The toolchain IAR Embedded Workbench, which supports more than 30 different processor families, is a complete IDE with everything needed; compiler, analysis tools, debugger, functional safety and security in one single view - ensuring quality, reliability and efficiency in your embedded application. The development tools support the following targets: 78K, 8051, ARM, AVR, AVR32, CR16C, Coldfire, H8, HCS12, M16C, M32C, MSP430, Maxim MAXQ, RISC-V RV32, R32C, R8C, RH850, RL78, RX, S08, SAM8, STM8, SuperH, V850.[2] The supported ARM core families are: ARM7 / ARM9 / ARM10 / ARM11, Cortex M0 / M0+ / M1 / M3 / M4 / M7 / M23 / M33, Cortex R4 / R5 / R7, Cortex A5 / A7 / A8 / A9 / A15 / A17. RISC-V tools supports RV32 32-bit RISC-V cores and extensions in the first version. Future releases will include 64-bit support and support for the smaller RV32E base instruction set, as well as functional safety certification and security solutions.
