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, highperformance, 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(R), ThreadX(R), and Nucleus(R). In addition, Oxford Semiconductor also makes available low-level controller drivers for other native USB stacks such as those included with Windows(R) CE and Linux(R) 2.6.x. Sample Applications Digital televisions Home media centers Portable media players Digital video cameras Digital still cameras Printers MP3 players External storage products Set-Top Boxes (STB) Personal Video Recorders (PVR) Personal Digital Assistants (PDA) 3G mobile phones DVD recorders
