JTAG/SWD Emulator with USB interface

J-Link 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 support is integrated in most professional IDEs such as IAR, Keil, Rowley, Renesas and many others.

Along with the OEM version (such as IAR J-Link, ATMEL SAM-Ice and others) more than 60,000 J-Links have been sold so far, making the J-Link likely to be the most popular emulator for ARM cores and the de-facto standard.
