    J-Link ULTRA Plus is a JTAG/SWD emulator designed for ARM/Cortex and other supported CPUs. It is fully compatible to the standard J-Link and works with the same PC software.

    Based on the highly optimized and proven J-Link, it offers even higher speed as well as target power measurement capabilities due to the faster CPU, built-in FPGA and High speed USB interface.
    It connects via USB to a PC running Microsoft Windows 2000, Windows XP, Windows 2003, Windows Vista or Windows 7. J-Link ULTRA Plus has a built-in 20-pin JTAG/SWD connector and comes with licenses for Unlimited Flash Breakpoints, RDI / RDDI and J-Flash.
