OXU210HP, Local bus to Hi-Speed USB Host, Peripheral/OTG controller
ƒ General Features
o Compatible with the USB
Specification, Revision 2.0 for highspeed (480 Mb/s), full-speed (12 Mb/s),
and low-speed (1.5 Mb/s) operations
o High-speed optimized host controller
with transaction translator for complete
backward compatibility with full-speed
and low-speed products
o Two high-speed USB ports; one port
remains host while the other can be
configured as peripheral, host or OnThe-Go (dual role)
o Simultaneous operation of both ports
ƒ Key Features
o Choice of 16-bit or 32-bit configurable
processor interface
o Fast microprocessor access cycle and
double/multi-buffering support for
USB transfers
o Host interface contains support for
common SoC DMA modes including
bursting and slave request/acknowledge
o Advanced power management controls
chip clocking and PHY function for
very low power consumption
o Integrated on-chip VBUS voltage
comparator and 100 mA charge pump
o 72 Kbytes of single-port SRAM
o True transfer level operation, with
transaction scheduling and handling
(data sequence toggle, error retry, etc.),
implemented in hardware
o Integrated PLL runs from a single 12MHz crystal or an external 12-MHz
clock source
o Operating temperature range: -40° to
85° C
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, OnThe-Go (OTG) controllers that have been specifically designed for embedded
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.
