Plug-and-play IEEE-1149.1 Boundary-Scan (JTAG)
controller for USB
The USB-1149.1/1E™ is a high-performance plug-and-play
IEEE-1149.1 Boundary-Scan (JTAG) controller for the
Universal Serial Bus (USB 2.0). The USB-1149.1/1E is a
high-speed device compliant with Revision 2.0 of the USB
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-1149.1/1E TCK output to the IEEE Standard 1149.1
compatible target system is programmable under software
control and supports speeds of up to 100MHz.
Other features include automatic signal delay
compensation for long cable lengths to the UUT,
programmable slew rate control on the TAP signals, and
I2C/SPI peripheral interfaces to support programming
serial EEPROM devices.
