Comprehensive target support:

• ICCAVR supports all AT90S and ATMega devices (except for 1200, which does not have SRAM), and AT94K FPSLIC. New enhanced  Megas such as the ATmega8 and ATmega16 are all supported.
• On the Mega103/Mega128: Standard version supports up to 64K bytes of Flash, PRO version supports up 128K bytes of Flash.
• Works with our companion product, ICCtiny™, for Tiny devices & AT90S1200.
• Strings may be placed in either SRAM or FLASH.
• Write interrupt handlers in C.
• Supports inline assembly and can interface with assembly modules.
• Byte operations.
• Automatic generation of bit IO instructions such as sbi, cbi, sbis, ... etc.

Powerful and user-friendly IDE:

• Fast 32-bits 95/98/NT/2000 program, accepts long file names.
• Uncluttered tabbed editor windows.
• C editor with syntax highlighting, jump to matching braces, block indents and outdents, extensive bookmark support, and code templates.
• Project Manager automatically generates standard makefile, one click to rebuild.
• Simple interface to select compiler options, including choose from a data base of popular chip configurations for memory address setup, select different versions of "printf" based on features and code size, and lots more!
• Built-in ANSI Terminal emulator for target communication.
• Built-in Application Builder to generate peripheral initialization code.
• Built-in ISP (In System Programming) tool with support for the STK200 dongle, LAWICEL ispAVRp dongle and the STK500 board. Can automatically download code after a successful project build.

ANSI C compiler:

• Modern fast C Compiler with full support for the ANSI C language. NOT a micro-C or extended K&R C, but a robust ANSI C front end written from the ground up, which has been in use for over 10 years.
• 32-bit longs, 32-bit IEEE single precision floating point.

Optimizations:

• Device specific instructions.
• Optimized switch handling.
• Algebraic simplifications.
• Block level common subexpression elimination.
• Advanced register allocation.
• Peephole optimization.

Assembler / Linker:

• Relocatable assembler and linker.
• Assembler directives include conditional processing, include files, macros and textual defines.
• Industry standard output formats include Intel HEX, and AVR COFF.

Debugger support:

• Full debugging in Atmel's AVR Studio, including data watchpoint. (Structure members info in PRO version only.)
• Support for the new Flash Design ISD (In System Debugger).
• Compilers produce listing files that are usable by most assembly level debuggers using conversion programs.

Libraries:

• Subset of ANSI C library including printf, memory allocation, strings, and math functions.
• Target-specific functions such as those for accessing EEPROM and various subsystems (SPI, ADC, I2C, LCD etc.)

Documentation:

• Online WinHelp also available as printed manual (> 100 pages) and in HTML Help format.

Third party tool support:

• Command line compilers callable from other editors (e.g. Codewright). Multiedit interface DLL also available.

Technical support:

• Excellent technical support via email. Typical turnaround time is the same day!
• Free 6 months maintenance update via download from the web.
• Low cost annual maintenance plans.

Professional version features:

• The ImageCraft Code Compressor ™ optimizer, which reduces final code by 8-18%. This state-of-the-art whole-program optimizer is not available in any other commercial embedded compilers. Graphical interface to RCS.
• Support for 128K bytes adressing on Mega103 and Mega128.
• Graphical interface to RCS.
• [Comming soon] Code BrowserTM.
• [Comming soon] Debug under AVR Studio includes structure members info.
• [Comming soon] Other advanced optimizations.

V6 for Windows availability:

• ICCAVR fully functional 30-day demo may be downloaded from our website.
• Standard version owners may upgrade to the Professional version for the difference in price.
