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.

Being fastest in its class, the regular J-Link already sets a very high standard for debugging and download performance.

J-Link Ultra raises the bar even higher, aiming to be the fastest emulator available!

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 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 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).
