The SEGGER J-Link ULTRA+ is a high-performance JTAG/SWD debug probe for Arm® Cortex-A/R/M and selected other cores. It delivers up to 4 MB/s download speed and supports target interface clocks up to 50 MHz, enabling rapid flash programming and responsive debug sessions.

Included Software & Licences

ULTRA+ comes with licences for Unlimited Flash Breakpoints, J-Flash, RDI/RDDI and the Ozone debugger, plus the J-Link GDB Server. Multi-platform host support (Windows, Linux and macOS) and broad IDE compatibility simplify integration into existing workflows.

Power & Trace-Related Capabilities

Built-in power measurement (up to 200 kSa/s, 50 µA resolution) helps profile low-power designs. SWO is supported, and a virtual COM (VCOM) interface provides convenient target UART over USB. For instruction trace via ETM, consider SEGGER J-Trace PRO.

Related Models

Within the J-Link family, engineers may also consider J-Link PLUS (same software ecosystem) or J-Link PRO (adds Ethernet and high-duty production use). Choosing ULTRA+ provides higher speed and power profiling in a compact USB probe.
