Emulator for ARM7/9, Cortex and Renesas RX cores
J-Link ULTRA+ 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+ has a built-in 20-pin JTAG/SWD connector and comes with licenses for Unlimited Flash Breakpoints, RDI / RDDI and J-Flash.
