The Transdimension's UHP112 provides a singlechip PCI-to-Universal Serial Bus (USB) solution. The UHP112 interfaces directly to any 32-bit 33 MHz PCI bus and is ideal for either onboard applications or add-in card applications. It can easily be configured to communicate in either a 3 V PCI environment or 5 V PCI environment simply by selecting the appropriate communications voltage level on the VIO input pin.

The UHP112 is a 3.3 V device fabricated in 0.35 m technology. Integrated dual-speed USB transceivers enable a single-chip PCI-to-USB solution.

The UHP112 supports the legacy peripherals feature, as defined in the OpenHCI Specification Release 1.0a.

An advanced power management capabilities interface compliant with PCI Bus Power Management Interface Specification Revision 1.1 is present to offer a variety of power-savings modes to the host system.

The UHP112 provides two downstream USB ports for connectivity with any USB compliant device or hub. Full-speed or low-speed peripherals are supported along with all of the USB transfer types: control, interrupt, bulk, or isochronous. The UHP112's OpenHCI compliance offers significant USB performance benefits and reduced CPU overhead compared to other host controllers.

The UHP112 is fully compatible with the Microsoft Windows Standard OpenHCD Drivers.

The UHP112 is supported natively as an OHCI compliant host controller under Windows 98, ME, XP and CE, as well as under MacOS and Linux. For customers using other operating systems, Soft- Connex Technologies' USBLink Host solution supports a wide range of products, such as AMX, ITRON, Linux, LynxOS, MS-DOS, Nucleus, OS-40, PowerTV, QNX, ThreadX, VRTX and VxWorks.

USBLink Host is also distinguished by the variety of USB devices that it can support, including: printers; audio, communication, human interface and mass storage devices; digital still and video cameras; Hubs; MP3 players; Host to Host cables and Bluetooth connectivity products. In addition, USBLink Host runs on both little endian (x86, ARM, SA, SH, ST) and big endian (PPC, MIPS) processors. For more information, please visit www.softconnex.com.
