4 TAP USB 2.0 and LAN Based JTAG
NetUSB-1149.1/E™ (4 TAPs) is an advanced USB 2.0 and LAN-based controller that can
be used in the testing and/or in-system programming
(ISP) of devices, boards, or systems compliant with the
IEEE-1149.1 standard. The NetUSB-1149.1/E controller supports concurrent
(gang) testing and in-system programming of CPLDs and
Flash devices at TCK rates of up to 80MHz. Up to 512
boards can be tested and programmed concurrently!
The controller connects to the computer either through
the USB interface or LAN interface for easy installation
at nearby or remote locations. Other features include
automatic signal delay compensation for long cable
lengths to the UUT, TAP signals, and GPIO discrete
signals which are individually programmable from 1.25V
to 3.3V, programmable slew rate control and pre-power up
test for shorts between power and ground traces on the
