The UHP112 is a 3.3 V device fabricated in 0.35
µm
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 inter-
face 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, inter-
rupt, 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 Blue-
tooth connectivity products. In addition, USBLink
Host runs on both little endian (x86, ARM, SA, SH,
ST) and big endian (PPC, MIPS) processors. For

Seamless integration with 3 V or 5 V PCI-based
computer products
Supports all USB compliant devices and hubs
Description
The Transdimension’s UHP112 provides a single-
chip 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 appro-
priate communications voltage level on the VIO input
pin.
