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) • Trace support for devices with built-in trace ports • 2 Mbyte trace memory buffer • Compact housing, fits easily on the desk • Silent, fanless design • Support for cycle accurate and compressed tracing • Supports 4 / 8 / 16 bit trace port at both full and half-rate clocking • Trace window synchronizes to source and disassembly window • Function trace shows called functions hierarchically
