High-Performance JTAG Controller Supports Both USB And LANs

The NetUSB-1149.1/E high-performance, intelligent boundary-scan JTAG controller can be connected either to a user's PC via the high-speed USB 2.0 or a 10/100BaseT Ethernet local-area network (LAN) interface. Devised by Corelis, the controller also offers testing and in-system programming of complex programmable-logic devices, FPGAs, and flash memories on up to four concurrent (ganged) JTAG chains.

Consequently, it delivers test vectors at a sustained test-clock (TCK) frequency of 80 MHz on all four JTAG chains while simultaneously verifying results in hardware at each individual test access point (TAP). Boundary-scan test vectors developed with Corelis' ScanPlusTPG Test Program Generator can be executed directly on the NetUSB-1149.1/E.

"Because it can connect via a LAN or the USB, the NetUSB-1149.1/E can be used in a variety of situations supporting both desktop and laptop PCs, in local or remote proximity to the PC," says Jim Rodgers, technical marketing engineer at Corelis. "By having a common test platform for both design and manufacturing, our customers will realize tremendous cost savings."

Available from stock, the NetUSB-1149.1/E controller ships with built-in self-test software and Plug-and-Play Windows 95/98/ME/NT/2000/XP device drivers. Prices start from $5950.
