Ultra-51Mx Microprocessor Development System for NXP 80C51Mx Extended-Memory Microcontrollers

Ashling's Ultra-51Mx Microprocessor Development System provides Software Development, In-Circuit Emulation, Source-level Debugging, Program Performance Analysis and Code Coverage measurement in one powerful integrated system, hosted under Windows™. All NXP 80C51Mx Extended-Memory Microcontrollers are fully supported, in addition to 80C51 and 80C51XA devices.

Ultra-51Mx debugging is completely non-intrusive and requires no target system resources. Full support is provided for Mx eXtended Memory addressing. With Ashling’s PathFinder-Mx source level debugger, Ultra-51Mx ensures fast and efficient development of Mx applications.

System Specification

PathFinder Source Debugger
PathFinder is Ashling's C Source-Level Debugger for the Ultra-51Mx, with multiple user-configurable windows, hover help and hover data display, point-and-click, drag-and-drop and splitter windows.

Controlled by button-bar, menus, mouse or automated script files, PathFinder’s Object-Oriented Monitoring and Editing System provides tree-structured “click to expand” access to all memory-areas, register sets, registers and bits of the Mx extended architecture.

Extended MX Architecture Support
The Ultra-51Mx Emulator features:

  • Support for Mx 16MB memory range
  • Extended Overlay Memory, breakpoints and triggers
  • Real-time Trace of expanded code execution
  • Extended 80C51 instruction-set
  • Easy conversion for 80C51 or P51XA

STARS Performance Analyser
Ashling’s STARS (Software Test, Analysis and Reporting System) Performance Analyzer option for the Ultra-51Mx measures the maximum, minimum and total execution time of every function in the program code, in real-time. You can measure and optimize the execution time of your Mx program, identify untested program paths, and verify conformance to an execution-time specification.

Code Coverage Measurement
Ashling’s “CodeScan” Code Coverage Measurement option for the Ultra-51Mx Emulator identifies all tested, untested and unreachable code in your program. You can verify that every instruction is tested and store a formal record of test completeness.


The PathFinder debugger displays the eXtended Memory and Instruction-Set of the Mx architecture. Changes in the processor’s registers since the previous break are highlighted in Red.

Emulation Specification
