Debug Probes - J-Link and J-Trace

JTAG/SWD debug probe with USB interface

SEGGER J-Links are the most widely used line of debug probes available today. They've proven their value for more than 10 years with over 400,000 units sold, including OEM versions and on-board solutions. This popularity stems from the unparalleled performance, extensive feature set, large number of supported CPUs, and compatibility with all popular development environments.

With up to 3 MBytes/s download speed to RAM and record breaking flashloaders, as well as the ability to set an unlimited number of breakpoints in flash memory of MCUs, the J-Link debug probes are undoubtedly the best choice to optimise your debugging and flash programming experience.

J-Link debug probes support ARM 7/9/11, Cortex, Microchip PIC32, Renesas RX CPUs and are supported by all major IDEs such as Keil MDK-ARM, GDB-based IDEs and SEGGER Embedded Studio. Here is the complete list of IDEs fully supporting J-Link / J-Trace.

Debug smarter and faster with J-Link debug probes!

Model Overview

There is a J-Link or J-Trace model available to fit all project needs. J-Trace is a full superset of J-Link with the added benefit of trace capabilities. J-Trace models are designed for one particular family of cores.

Available models vary in price, speed, and other hardware features such as built-in trace memory and on-board Ethernet, as well as advanced software features. The advanced software features are:

  • J-Flash (High-speed production grade flash programming software)
  • J-Link Unlimited Flash Breakpoints (Unlimited number of breakpoints while debugging in flash memory)
  • J-Link RDI / RDDI (Support for RDI / RDDI compatible debuggers)

4 The download speeds listed here are the peak download speeds that can be achieved by the particular J-Link model. The actual download speed may be lower as it depends on various factors, such as, but not limited to: The selected debug interface & speed, the CPU core and its operating frequency, other devices in the JTAG chain in case JTAG is used as target interface.

The following tables (click on the images) show the features which are included in each J-Link / J-Trace model.

Hardware FeaturesHardware features like Ethernet interface, USB full- / high-speed interface, etc. are J-Link model specific features which can not be updated or changed by software updates.


Software FeaturesSoftware features are features implemented in the software primarily on the host. Software features can either come with the J-Link or be added later using a license string from Segger.


Supported CoresSupported cores - Support for additional / new cores may be added to existing J-Link models with a new firmware version as far as the exisiting J-Link hardware allows it.

J-Link PRO

J-Link PRO

J-Link PRO is a refined version of the regular J-Link. It has an Ethernet interface in addition to the USB interface, as well as two additional LEDs which are used as hardware status indicators. It connects via Ethernet or USB to the host, running Windows, Linux or Mac OS X.

Main features

  • Fully compatible to J-Link.
  • Ethernet interface. USB 2.0 Hi-Speed interface
  • Supported CPUs: Any ARM7/9/11, Cortex-A5/A8/A9, Cortex-M0/M1/M3/M4, Cortex-R4/R5 and Renesas RX100 / RX200 / RX610 / RX621 / RX62N / RX62T / RX630 / RX631 / RX63N
More Information

J-Link ULTRA+

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.

Main features

  • Comes with integrated licenses for: Unlimited breakpoints in flash memory, RDI / RDDI and J-Flash.
  • Fully compatible to standard J-Link.
  • Very high performance for all supported CPU cores.
  • Download speed up to 3 MByte/second Hi-Speed-USB 2.0 interface.
More Information

J-Link PLUS

J-Link PLUS is a USB powered JTAG emulator supporting a large number of CPU cores.
Based on a 32-bit RISC CPU, it can communicate at high speed with the supported target CPUs. J-Link is used around the world in tens of thousand places for development and production (flash programming) purposes.

Main features

  • Comes with integrated licenses for: Unlimited breakpoints in flash memory, RDI / RDDI and J-Flash
  • Fully compatible to the standard J-Link
  • Direct download into flash memory of most popular microcontrollers supported
More Information

J-Link BASE

J-Link BASE is a USB powered JTAG emulator supporting a large number of CPU cores. Based on a 32-bit RISC CPU, it can communicate at high speed with the supported target CPUs.

Main features

  • Direct download into flash memory of most popular microcontrollers supported
  • Supported CPUs: Any ARM7/9/11, Cortex-A5/A8/A9, Cortex-M0/M1/M3/M4, Cortex-R4, Microchip PIC32 and Renesas RX100 / RX200 / RX610 / RX621 / RX62N / RX62T / RX630 / RX631 / RX63N

More Information

J-Trace for Cortex-M

J-Trace for Cortex-M is a JTAG emulator designed for Cortex-M cores which includes trace (ETM) support. J-Trace for Cortex-M can also be used as a J-Link and it also supports ARM7/9 cores. Tracing on ARM7/9 targets is not supported.

Main features

  • Has all the J-Link functionality
  • Hi-Speed-USB 2.0 interface
  • JTAG speed: 25 MHz Works with all currently available Cortex-M devices at 100 MHz trace clock
  • Supports tracing on Cortex-M0/M0+/M1/M3/M4 targets
More Information

J-Trace PRO for Cortex-M

J-Trace PRO for Cortex-M is setting a new standard for trace probes. It enables continuous streaming trace via its Gigabit Ethernet interface, lifting the limitations by internal buffers and slow data transmission. J-Trace PRO can capture complete traces over long periods - thereby enabling the recording of infrequent, hard-to-reproduce bugs. This is particularly helpful when the program flow 'runs off the rails' and stops in a fault state.

Main 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
  • Works with all currently available Cortex-M devices up to 300 MHz trace clock
  • Supports tracing on Cortex-M0/M0+/M1/M3/M4/M7 targets
