Benefits

Every IAR C/C++ Embedded Compiler contains both generic global optimizations as well as low-level chip-specific optimizations that ensure a small code size while taking advantage of all the specific features of your selected device.

IAR has compiler support for the following processors: 8051 ARM Atmel AVR Atmel AVR32 Freescale ColdFire Freescale S08 Freescale HCS12 Maxim MAXQ Microchip dsPIC/PIC24 Microchip PIC18 National CR16C NEC 78K0 NEC V850 Renesas H8 Renesas M16C / R8C Renesas M32C Renesas R32C Renesas R8C/Tiny Samsung SAM8 Sharp MK5 TI MSP430

Reuse of code and migration to new microcontroller architectures is made easy as each IAR C/C++ Compiler uses the same naming convention.

Whether you have a tight project schedule or are just eager to get started, IAR Embedded Workbench contains configuration files, code examples and template projects to get you going fast.
