OXU210HP
USB2.0 High-Speed Host, Peripheral and OTG Controller
Features
High‐performance, high‐speed USB dual‐role (host/peripheral)
controller
Compatible with the Universal Serial Bus Specification, Revision 2.0
for high‐speed (480 Mb/s), full‐speed (12 Mb/s), and low‐speed
(1.5 Mb/s) operations
High‐speed optimized host controller with transaction translator
for complete backward compatibility with full‐speed and
low‐speed products
Two high‐speed USB ports; one port remains host while the other
can be configured as peripheral, host, or OTG (dual role)
Simultaneous operation of both ports
Processor interface is either 16 bits (BGA) or configurable 16 or 32
bits (LQFP)
Fast microprocessor access cycle and double/multi buffering
support for USB transfers
Host interface contains support for common SoC DMA modes
including bursting and slave request/acknowledge protocols
Complete host, peripheral and OTG software solutions for
popular microprocessors using many of the most popular
operating systems
Advanced power management controls chip clocking and PHY
function for very low power consumption
Integrated on‐chip VBUS voltage comparator and 100 mA charge
pump
72 Kbytes of single‐port SRAM provides space for data structures
and buffer space for transfer data
True transfer level operation, with transaction scheduling and
handling (data sequence toggle, error retry, etc.), implemented in
hardware
Integrated PLL runs from a single 12‐MHz crystal or an external
12‐MHz clock source
