controller for USB
The USB-1149.1/4E™ is a high-performance plug-and-play
IEEE-1149.1 Boundary-Scan (JTAG) controller for the
Universal Serial Bus (USB 2.0). The USB-1149.1/4E is a
high-speed device compliant with Revision 2.0 of the USB
Bus Specification (backward compatible with the
full-speed features of Revision 1.1).
The voltage level of the parallel I/O and the TAP
interface is software programmable and can be set to any
voltage between 1.25V and 3.3V in increments of 0.05V.
The USB-1149.1/4E TCK output to the IEEE Standard 1149.1
compatible target system is programmable under software
control and supports speeds of up to 100MHz.
