J-Link Ultra (8.16.00)
Hi-Speed JTAG/SWD Emulator for ARM7/9, Cortex and Renesas RX cores with USB interface, Segger

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.

Since the PC-Software, form factor and connectors are the same as for the regular J-Link, it can be used with any software compatible with J-Link and any adapter, such as the JTAG-isolator.
Just like for the regular J-Link, the Unlimited Flash Breakpoints option for enhanced debugging of programs running in the flash of microcontrollers is available.

The J-Link is natively supported by IAR EWARM, KEIL µVision, Rowley Crossworks, and CodeSourcery G++. With the RDI and GDB-Server extensions, the supported tool-chains also include Atollic TrueStudio, Yagarto, and other RDI or GDB compatible development environments. If your development environment does not supply a Flash Loader for your device, the J-Link Ultra includes flash loaders designed for all popular devices with internal Flash.

The Unlimited Flash Breakpoints option allows the user to set an unlimited number of breakpoints while debugging within a device’s internal flash memory. This overcomes the hardware breakpoint limitations present in most common microcontrollers (2 on ARM7/9, 4 on Cortex-M0, typically 6 on Cortex-M3 and 8 on Renesas RX).
