J-Link Ultra

J-Link Ultra is a JTAG/SWD emulator designed for ARM/Cortex
and other supported CPUs. It is fully compatible to the standard
J-Link and works with the same PC software. 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. It con-
nects via USB to a PC running Microsoft Windows 2000 or later.
For a complete list of all operating systems which are sup-
ported, please refer to Supported OS on page 19.. J-Link Ultra
has a built-in 20-pin JTAG/SWD connector.
1.3.3.1 Additional features
