SEGGER develops software development tools and ANSI C software components (middleware) for embedded systems in several industries such as telecom, medical technology, consumer electronics, automotive industry and industrial automation. SEGGER's intention is to cut software development time for embedded applications by offering compact flexible and easy to use middleware, allowing developers to concentrate on their application.
SEGGER also created highly integrated, cost-effective programming and development tools, such as the Flasher (stand-alone flash programmer) and the industry leading J-Link/J-Trace emulator. J-Link is an industry-leading family of JTAG emulator, J-Link is a JTAG emulator to assist in development, debugging and production, which has rapidly become the industry standard for debug access to ARM cores with and without trace. Main features include high download-speed into RAM and flash memory, the ability to set an unlimited number of breakpoints in flash memory of MCUs.
J-Link is a JTAG emulator for ARM7, ARM9, ARM11, ARM Cortex™ cores. This is the only JTAG emulator that can add SEGGER's patented Flash breakpoint software to an RDI compliant debugger to enable the setting of multiple breakpoints in Flash while running on an ARM device which is typically hindered by the two available hardware breakpoints. Based on a 32-bit RISC CPU, it can communicate at high speed with the supported target CPUs. 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. For enhanced emulation features SEGGER also offers a Trace Emulator, J-Trace that works with the ARM ETM interface and enables engineers to trace back their code execution. J-Link/J-Trace allows:
- High visibility of tool chain parameters
- The de-facto JTAG-standard (J-Link)
- Hardware independent breakpoints
- Debugger independent flash download
- Supported CPUs: Any ARM7/9/11, Cortex-A5/A8/A9, Cortex-M0/M1/M3/M4, Cortex-R4, RX610, RX621, RX62N, RX62T, RX630, RX631, RX63N

Development Tools (J-Link/J-Trace)
Based on embedded software SEGGER created an industry-leading family of JTAG emulators with and without trace. Main features include high download-speed into RAM and flash memory, the ability to set an unlimited number of breakpoints in flash memory of MCUs. Supports ARM 7/9/11, Cortex™ and ColdFire™ and various IDEs:

|J-Link Ultra: Emulator for ARM and Cortex-M3 coresJ-Link Ultra: Emulator for ARM and Cortex-M3 cores|
J-Link Ultra is a JTAG/SWD emulator designed for ARM/Cortex and other supported CPUs. Based on the highly optimized and proven J-Link, it offers even higher speed as well as target power measurement capabilities due to the faster CPU, built-in FPGA and High speed USB interface.
Download speed up to 1500 Kbytes/second
|J-Trace ARM: ARM JTAG and Trace EmulatorJ-Trace ARM: ARM JTAG and Trace Emulator|
A JTAG debugger with Trace. The J-TRACE can be used as a standard JTAG by using the JTAG cable or by swapping to the TRACE cable the Trace features can be used.
|J-Trace Cortex-M: JTAG emulator with trace support for Cortex-M coresJ-Trace Cortex-M: JTAG emulator with trace support for Cortex-M cores|
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.
|JTAG IsolatorJTAG Isolator|
The J-Link JTAG Isolator can be connected between J-Link ARM and any ARM-board that uses the standard 20-pin JTAG-ARM connector to provide electrical isolation. This is essential when the development tools are not connected to the same ground as the application.
