Cosmic 68HC11 Cross Development Tools

NXP™ and the NXP logo are trademarks of NXP Semiconductor, Inc. All other product or service names are the property of their respective owners. ©NXP Semiconductor, Inc. 2004

Cosmic's toolchain for the 68HC11 family is part of a complete and uniform product line incorporating over 40 years of innovative design and development. Cosmic's familiar and easy to use software interface is available for all Freescale microcontrollers to simplify the migration between targets. All Cosmic products include one year of technical support and updates.

Integrated Development Environment

All Cosmic C Cross Compilers for Windows include IDEA - Cosmic's own integrated development environment which is preconfigured for the 68HC11 family of processors. IDEA is designed specifically for developing embedded applications with Cosmic compilers. IDEA integrates an editor, project manager, graphical smart build/make facility, program analyzer, link file generator, documentation manager and ZAP debugger into one easy to use environment running under Windows.
Click here for more information about IDEA.

Third Party IDE Integration

Most Cosmic compilers can be easily integrated in third party IDEs.


The C Compiler package includes: an integrated development environment with optimizing ANSI-C cross compiler, macro assembler, linker, librarian, hex file generator, object format converters, debugging support utilities, run-time library source code, and a multi-pass compiler command driver. The compiler also supports non-intrusive C source-level debugging with Cosmic's line of ZAP debuggers.

68HC11 specific features include:
  • 68HC11 Family
    The Cosmic 68HC11 compiler generates highly efficient code for the entire 68HC11 family of microcontrollers.
  • ANSI and ISO C Compiler
    The Cosmic 68HC11 compiler follows ANSI and ISO rules and conventions. All code and libraries are optimized specifically for the 68HC11 processor cores.
  • Reentrant and Recursive
    All code is fully reentrant and recursive using standard ANSI stack frame conventions.
  • Bank Switching
    Automated source level support for 68HC11 K4 and C0 Code bank switching (Paging).
  • Moveable Code Feature
    Moveable code feature is designed to make boot loaders and RAM based code easy to create and maintain. The Linker automatically creates a segment in ROM to store moveable code. At run time, use the supplied library functions to locate and copy call the moveable code into RAM at any time.
  • Byte EEPROM Support
    Compiler provides transparent support for on-chip EEPROM (library source included). Allocate any C data object(s) to the EEPROM and the compiler takes care of the formatting and programming.
  • In-line Assembly
    The compiler provides three convenient methods for adding assembly code inside a C program. Includes an argument passing mechanism.
  • IEEE-754 Floating Point
    Supports IEEE 32 bit single and 64 bit double precision floating point formats with full ANSI libraries (Source code included).
  • C Support for Zero Page
    Compiler source extensions provide efficient use of the 68HC11 direct addressing mode.
  • Absolute Listings
    Optionally produce relocatable and/or absolute C interspersed with the corresponding Assembly listings.
  • Automated Check Sums
    Easy to use check sum facility and library (Source included) allow users to quickly implement an efficient check sum on any or all sections. Check sum calculation and insertion is transparently managed by the linker.
  • Mixed C and Assembly
    Cosmic tools support mixed C and Assembly applications. Including Assembler support for C #defines and #includes. so C and assembly language modules may share common constants and macros.
  • Host Independent Formats
    The Cosmic relocatable and absolute object formats are host independent. This allows user's on PC, SUN and HP to share objects for linking and debugging.
  • IEEE-695 and ELF/DWARF Debug Support
    The Cosmic compiler suite supports the IEEE and ELF DWARF standard debug formats used by many popular emulators and logic analyzers.
  • In-Circuit Emulator Compatibility
    Cosmic's 68HC11 compiler is compatible with emulators from Hitex, I-Systems, Lauterbach and NOHAU.
  • Flexible Compiler Interface
    Cosmic compilers are designed to be powerful and flexible so they can be used with virtually any environment. Use Cosmic's own IDEA interface or use your favorite editor, make utility and/or source code control system - It's Your Choice!!
  • OS Compatibility
    Cosmic HC11 compiler is compatible with most HC11 operating systems and real-time kernels including specific ports from CMX and MicroC/OS-II.
ZAP Debugger

Cosmic's ZAP debugger is a full featured C and Assembly language source-level debugger for embedded applications. ZAP's intuitive graphical interface is uniform for all targets and execution environments. ZAP is available in 2 execution versions for the HC11. (1) ZAP SIM Debugger with included processor Simulator. (2) ZAP Monitor for use with NXP EVS and EVM boards.
