IAR J-Trace is a small ARM hardware debug trace device. It connects via USB to the PC host running Windows. IAR J-Trace integrates seamlessly into IAR Embedded Workbench for ARM and also works as a standard JTAG debugger through a separate JTAG port.

General features
• USB-driven JTAG and Trace (38-pin Mictor) interface
• Supports all ARM7 and ARM9 devices
• No power supply required, powered through USB, although external power supply plug is available
• JTAG speed 12 MHz • Auto speed recognition
• USB-2 full speed (12Mbit/sec)
• Adaptive clock based on RTCK JTAG signal
• All signals can be monitored, target voltage can be measured
• 20-pin standard JTAG connector, 38-pin standard Trace Mictor connector
• USB, 20-pin flat cable and 38-pin trace cable included
• Full integration with the C-SPY Debugger; advanced debugging features available from C-SPY.
• Integration into IAR Embedded Workbench for ARM makes setup and use easy
• Supported platforms: Windows 2000 and Windows XP

Trace features
• Trace supports up to 200 MHz full and 100 MHz half clock rate
• Trace based on ARM ETM (Embedded Trace Macrocell)
