J-Link ULTRA+

J-Link ULTRA+ is a JTAG/SWD debug probe designed for ARM/Cortex. 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.

Why Use J-Link ULTRA+?

Speed

Up to 3 MByte/s download speed make J-Link ULTRA+ the fastest debug probe on the market. Using TCP/IP instead of USB eliminates latencies from USB usage, resulting in higher debugging speed.

Flash Breakpoints

The J-Link software comes with an additional feature, called Unlimited Flash Breakpoints. Unlimited Flash Breakpoints allow the user to set an unlimited number of breakpoints when debugging in flash memory.

Ozone – J-Link Debugger

Ozone is the debugger for J-Link and J-Trace. It includes all well-known debug controls and information windows and makes use of the best performance of J-Link and J-Trace debug probes.

J-Flash

J-Flash is a PC software to program internal and external flash memory of a microcontroller-based embedded system via J-Link or Flasher.

Further Advantages

Built-in VCOM functionality
Supports direct download into RAM and flash memory
Supports a broad range of microcontrollers
Multiple CPUs supported—8051, PIC32, RX, ARM7/9/11, Cortex-M/R/A, RISC-V [More..]
Additional LEDs for power and RESET indication

J-Link ULTRA+ Licensing

J-Link ULTRA+ comes with licenses for all J-Link related SEGGER software products: J-Link Unlimited Flash Breakpoints, J-Link RDI / RDDI, J-Flash, J-Link GDB Server, providing the optimum debugging solution for professional developers.

J-Link ULTRA+ can be used with almost all ARM debuggers, enabling download to flash memory with an unlimited number of breakpoints when debugging programs located in flash memory of most popular ARM microcontrollers. It also comes with the license to use J-Flash, SEGGER's popular flash programming software.
