Market Leading Development Tools—J-Link and J-Trace PRO
The J-Link debug probes with their outstanding performance, robustness, and ease of use are the market leading debug probes today. The J-Trace PRO sets a benchmark for instruction tracing with its streaming trace function that enables unlimited tracing at full clock speed.
J-Trace PRO: The Leading Trace Solution
J-Trace PRO is an advanced debug probe that supports Arm's advanced tracing features of Arm Cortex cores.
Features
- Supports Streaming Trace (trace data is streamed to PC/debugger in real time, unlimited trace buffer)
- Has all the J-Link functionality
- Gigabit Ethernet interface
- SuperSpeed USB 3.0 interface (1.2 GBit/s)
- JTAG speed: 50 MHz
- Works with all currently available Cortex-M devices up to 150 MHz ETM trace clock (300 MHz CPU clock)
- Supports tracing on Cortex-M/R/A targets
- Free software updates
- 64 MiB on-board trace buffer for legacy one-shot tracing mode
J-Link
SEGGER J-Links are the most widely used line of debug probes available today. They've proven their value for more than 10 years.
Features
- Ultrafast download speed
- Unlimited breakpoints in flash memory
- Real-Time Transfer technology for extended debug information
- All popular devices are supported (Arm, RISC-V, 8051, PIC32, RX)

Supported devices
SEGGER Debug and Trace Probes support a wide range of CPUs and architectures.
The list is always valid for the latest version (highest version number) of the software. This may be a release (even version number) or a beta version (odd version number) since support for some devices is usually added in a beta phase first.
Note that a device may still be supported even if it is not on the list. Device not listed? Please don’t hesitate to contact us.
