OXU210HP, Local bus to Hi-Speed USB Host, Peripheral/OTG controller
Highlights
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.
General Features
o Compatible with the USB
Specification, Revision 2.0 for high-
speed (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 On-
The-Go (dual role)
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.
o Simultaneous operation of both ports
The OXU210HP supports all USB transfer modes (control, interrupt, bulk, and
isochronous) and is supported with USB device drivers.
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
protocols
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 12-
MHz crystal or an external 12-MHz
clock source
o Operating temperature range: -40° to
85° C
