J-Link

JTAG/SWD Emulator with USB interface

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. J-Link is used around the world in tens of thousand places for development and production (flash programming) purposes. 

J-Link is supported by all major IDEs such as IAR EWARM, Keil MDK, Rowley CrossWorks, Atollic TrueSTUDIO, IAR EWRX, Renesas HEW, Renesas e2studio, and many others. 

Including all models, more than 100,000 J-Links have been sold so far, making J-Link probably the most popular emulator for ARM cores and the de-facto standard.

  • All JTAG signals can be monitored, target voltage can be measured
  • Target power supply: J-Link can supply up to 300 mA to target with overload protection

1 The unlimited breakpoints in flash memory feature can be used free of charge for evaluation. The evaluation period is not time limited. For commercial use a separate license is required.
2 As a legitimate owner of a SEGGER J-Link, you can always download the latest software free of charge. Though not planned and not likely, we reserve the right to change this policy. Note that older models may not be supported by newer versions of the software. Typically, we support older models with new software at least 3 years after end of life.
3 J-Link allows multiple applications to access a CPU at the same time. This has numerous applications. J-Link commander can be used in parallel to a debugger, a tool to communicate via DCC can be used in parallel to a debugger or a visualisation tool such as Micrium's u/C-Probe or SEGGER's kernel viewer embOSView. This feature is currently not available for Cortex A and R cores.
4 The MAC and Linux versions are fully usable, but limited to the following components:
J-Link Commander, command line GDBServer, shared library (DLL-equivalent).


Package content
