Introduced at Embedded Live in London, the JTAGLive USB controller from JTAG Technologies is a single TAP IEEE Std. 1149.1 boundary-scan controller.

While the company's JTAGLive boundary-scan utility tools already supports the use of the JTAG 'cables' from Xilinx and Altera, as well as JTAG Technologies' established range of IEEE 1149.x controllers, increasingly JTAGLive users have been requesting a dedicated, low-cost, connection system that works 'out of the box' with the JTAGLive suite.

The JTAGLive USB controller is PC-powered and features a single test access port in JTAG Technologies' standard pin-out. It offers a maximum programmable TCK speed of 6MHz and also features programmable output voltages and input thresholds.

The controller has been designed for use exclusively with the JTAGLive suite of software tools that includes Buzz (a free-of-charge continuity tester), Clip (an interactive cluster test generator) and Script (a powerful Python-based boundary-scan scripting system).

The JTAGLive USB controller costs $265 and is available for on-line ordering.
