Texas Instruments (TI) has announced that it is the first semiconductor company to receive certification from the USB Implementer's Forum (USB-IF) for its SuperSpeed USB (USB 3.0) four-port extensible host controller (xHCI). In addition to the four-port host controller, the TUSB7340, TI also achieved certification for its two-port host controller, the TUSB7320.
TI's four- and two-port host controllers support applications such as notebooks, desktop computers, workstations, servers, add-in cards and ExpressCard implementations, as well as PCIe-based embedded host controllers for HDTVs, set top boxes and gaming console applications.
The new USB-IF-certified SuperSpeed USB host controllers come in a compact WQFN package and are sampling now. They will be in volume production in May 2011, with suggested resale pricing of US$4.50 for the four-port TUSB7340 and US$3.50 for the two-port TUSB7320, in quantities of 1,000.
