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 thousands of places for development and production (flash programming) purposes.
You can develop your own applications to utilize the entire functionality of J-Link with the J-Link Windows SDK (see below).
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.

However, if you also would like any of the other optional components mentioned above, it is recommended to purchase the J-Link PLUS, which consists of a J-Link with the J-Flash, RDI and Unlimited Flash Breakpoints add-ons at a price cheaper than getting just the J-Link and J-Flash separately, and cheaper than getting the J-Link and RDI support with Unlimited Flash Breakpoints separately. The only combination cheaper than the J-Link PLUS would be to buy this J-Link and the RDI Support add-on separately without the Flash Breakpoints option, but that's only $51 cheaper than the J-Link PLUS, whereas purchasing the J-Link PLUS saves you more than $900 off the price of all those components separately.
See also the J-Link ULTRA+ which provides much faster speeds, lots of add-on software, and a few other features, or the J-Link PRO which provides the ULTRA+'s speeds plus an Ethernet interface and also all the software add-ons.
