OXU210HP
USB2.0 High-Speed Host, Peripheral, and OTG Controller
Description
The Oxford Semiconductor OXU210HP is a single-chip,
high-speed USB host and high-speed USB peripheral
controller with integrated transceivers. It is the fourth
controller in the family of integrated, low-cost, high-
performance, On-The-Go (OTG) controllers that have
been specifically designed for embedded systems.
The OXU210HP operates up to 480 Mb/s, using a
compatible EHCI-based core. It also includes an
integrated transaction translator that supports full-speed
(12 Mb/s) and low-speed (1.5 Mb/s) USB peripherals.
The selectable 16- and 32-bit processor interface is
compatible with a variety of CPUs. A large 72-Kbyte
buffer has also been integrated to reduce interrupts and
minimize CPU overhead.
The OXU210HP supports all USB transfer modes
(control, interrupt, bulk, and isochronous) and is
supported with USB device drivers and the Oxford
Semiconductor USBLink product suite. The USBLink
host, peripheral, and OTG stacks have been ported to a
wide variety of real time operating systems including
VxWorks
®
, ThreadX
®
, and Nucleus
®
.
In addition, Oxford Semiconductor also makes available
low-level controller drivers for other native USB stacks
such as those included with Windows
®
CE and Linux
®
2.6.x.
