SEGGER J-Links are the most widely used line of debug probes available today. They’ve been proven for more than 10 years with over 250,000 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 optimize your debugging and flash programming experience.
J-Link debug probes support all ARM 7/9/11, Cortex™, Microchip PIC32™, Renesas RX™ CPUs and are supported by all major IDEs such as IAR EWARM, Keil MDK, Rowley CrossWorks, Atollic TrueSTUDIO, IAR EWRX,Renesas HEW, Renesas e2studio, including GDB based IDEs, and many others.
Debug smarter and faster with J-Link debug probes!
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 sotware 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)

7The 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.
