Cosmic 68HC05 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 68HC05 family is part of a complete and uniform product line incorporating over 20 years of innovative design and development. Cosmic's familiar and easy to use software interface is available for all NXP 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 68HC05 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 2000 and XP.

Third Party IDE Integration

Most Cosmic compilers can be easily integrated in third party IDEs such as Borland Codewright and RistanCase Development Assistant for C. Click here for more information.


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.

68HC05 Specific features include:
  • ANSI and ISO C Compiler
    The Cosmic 68HC05 compiler follows ANSI and ISO rules and conventions*. All code and libraries are optimized specifically for the 68HC05 processor core.
  • 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 single floating point formats with full ANSI libraries (Source code included).
  • C Support for Zero Page
    Compiler source extensions provide efficient use of the 68HC05 direct addressing mode and single byte pointers.
  • Absolute Listings
    Optionally produce relocatable and/or absolute C interspersed with the corresponding Assembly listings.
  • Check Sum Feature
    Easy to use check sum facility and library (Source included) allows users to quickly implement an efficient check sum on any or all sections. Check sum calculation and insertion is managed by the linker.
  • Assembler Accepts C Defines
    The assembler accepts most C defines and includes so configuration defines may be easily shared between C and Assembly modules.
  • 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 68HC05 compiler is compatible with emulators from Ashling, Hitex, NXP and Lauterbach.
  • 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!!
* Due to processor limitations, reentrancy, stack frame conventions and double precision floats are not supported.

ZAP Debugger

ZAP is a full featured source-level debugger available for Windows and OSF Motif. ZAP's intuitive graphical interface is uniform for all targets and execution environments. ZAP is available in Simulation (SIM), and NXP MMDS/MMEVS In-circuit emulator (MMD) configurations for the 68HC05.
Click here for general information about the ZAP debugger.
ZAP 68HC05 for MMDS/MMEVS specific features include:
  • Real-time debugging
    ZAP MMDS provides a low cost real-time debugging environment.
  • Hardware Breakpoints
    ZAP provides efficient use of the MMDS hardware breakpoint facility.
  • Complex Event triggers
    Set multiple complex events and triggers to stop or record real-time execution data. Also records and displays time stamp and logic clips.
  • Dual Port Real-time memory
    Monitor and update memory while code runs in real time. Includes variable refresh rate.
  • Real-time Trace
    Flexible trace feature displays recorded trace in several formats including raw cycle data, C source, disassembly, and C source interspersed with the corresponding disassembly. Export any trace format to a file for post processing and documentation.
* ZAP MMDS also supports NXP's Modular Evaluation System MMEVS05 evaluation boards. The MMEVS offers all the same features as the MMDS except real time trace, event triggering and dual port memory.
