IAR I-jet
Debugging probe enabling powerful features in IAR Embedded Workbench for Arm.
01
Native support in IAR Embedded Workbench
Integrated tools simplify your development workflow. Our feature-rich in-circuit debugging probe enable powerful features in IAR Embedded Workbench.
02
Best in class performance
I-jet provides a fast debugging platform via JTAG and SWD/SWO with download speeds of up to 1,89 MByte/sec and support for SWO speeds of up to 60MHz. The JTAG and Serial Wire Debug (SWD) clocks up to 32MHz (no limit on the MCU clock speed).
03
Broad support for Arm
Supports all Arm7/Arm9/Arm11 cores, Arm Cortex-A/R/M cores from all Silicon Vendors with Automatic core recognition and JTAG/SWD detection. Also supports Micro Trace Buffer (MTB) for ARM Cortex-M0+.
04
Power Debugging
Power Debugging provides developers with information about how the software implementation of an embedded system affects the system’s power consumption. I-jet can supply Target power of up to 400mA and consumption can be measured with ~200µA resolution at 200kHz.
