Software Quality Assurance
Built-in options for high-speed, non-intrusive real-time Performance Analysis, Code Coverage and report generation. Symbolic function trace, time-stamping, timing analysis and automatic software-verification reports, using a dedicated real-time measurement subsystem.

Banked Program Support
Optional built-in support for banked program development, including banked code memory, banked code breakpoints, banked triggers and banked code execution trace. Auto configuration for banked programs up to 1MB.

Languages Supported
Keil C, IAR C, Altium-Tasking C, Ashling ASM51, Intel ASM51, Keil RTX51 RTOS.

Clock Speed
Emulation clock speeds to 48MHz. Full support for x2 clock devices.

Host
PC with Windows™9x/2000/Me/ NT/XP, standard RS232 serial port.

Flash microcontroller emulation
Full-speed code overlay memory emulates On-Chip Flash microcontrollers.

The PathFinder Source Debugger provides real-time in-circuit emulation and source-level debugging for the NXP 80C51 microcontroller family with mouse, command-line, accelerator-key and button-bar controls.

Emulator Memory
1MB Emulator Code Overlay Memory and 1MB Emulator Xdata Overlay Memory.

On-the-Fly Debugging
Full On-the-Fly, non-intrusive debugging: You can set breakpoints, define a trigger, view trace contents and monitor variables while your program is executing.

Trace Display

• 32K Frames by 96 bits trace buffer, with variable trace length.
• Time-stamp on every traced frame.
• Optional trace expansion to 512K Frames.
• Display signals in cycle-by-cycle, hex, or source code.
• Full real-time tracing of address, data, ports, control and external buses.
• Save/load trace display.
• Compare trace against reference traces.

Triggering

• Six multiple trigger Event recognizers; symbolic, binary, or hex values.
• Trigger on Boolean combinations of the Event recognizers.
• Trigger on address and/or data values or range(s).
• Pre/center/post trace triggers.
• Save/load trigger definition files.
• Modify trigger On-the-Fly.

Breakpoints

• 64K code breakpoints (optional upgrade to 1MB).
• 64K Xdata read and 64K Xdata write breakpoints.
• Break on frames after stop trigger.
• Break on Trace buffer full.
• Execution timer breakpoint.
• External signal breakpoint.
• All breakpoints are halt-before-instruction, non-intrusive, real-time.

Variables
Full expression handling for assembler for C and assembly. Variable monitoring, including complex arrays and structures. On-the-fly variable monitoring.

Performance Analyzer
STARS-51 (Software Test, Analysis and Reporting System) high-speed, non-intrusive real-time performance analysis system option with full bank-memory support. Symbolic Function Trace, timing analysis and automatic software-verification reports.

Code Coverage
CodeScan-51 Code Coverage system option for software quality assurance. Measures all tested, untested and partially-tested code, by instruction, by line, by function, by module and by program.

Power Supply
Stand-alone in-circuit emulator with standard 115Kbits/s serial connection to PC. Supplied with 100V-230V 50/60Hz Universal power unit.

Ultra-51 Product Range please specify device-type when ordering

Upgrade Path
All Ultra-51 systems can be easily field-upgraded to a different processor type. Ashling's continuing technical co-operation with NXP Semiconductors ensures that development support is provided for each new 80C51, 80C51Mx2, XA and Smart Card derivative introduced by NXP.
