Description
Lucent Technologies Microelectronics Group’s USS-
312 provides a single-chip PCI-to-Universal Serial
Bus (USB) solution. The USS-312 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 USS-312 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 USS-
312’s OpenHCI compliance offers significant USB
performance benefits and reduced CPU overhead
compared to other host controllers.
The USS-312 is fully compatible with the Microsoft
Windows Standard OpenHCD Drivers.
The USS-312 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 USS-312 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.
