Features
OXU121HP
USB On-The-Go Full-Speed Host and High-Speed
Peripheral Controller
„
Single‐chip USB OTG full‐speed host and high‐speed peripheral
controller
† Replaces two‐chip system
† Reduces system cost and board space
† Minimizes system design complexity and power
consumption
† Simultaneous host and peripheral operation
„
Compatible with the Universal Serial Bus Specification, Revision 2.0
and the On‐The‐Go Supplement to the USB Specification 2.0,
Revision 1.0
„
Single 3.3 V power supply, flexible I/O voltage of 1.65 V to 3.6 V
(LVCMOS/TTL) to interface to a wide range of MCUs
„
Low power operation, suitable for mobile applications
† 30 mA (max) for host operation
† 75 mA (max) for peripheral operation
„
Power saving mode for the host controller and suspend mode for
peripheral controller
„
Integrated on‐chip charge pump, supports up to 100 mA of
current, enables support for broad range of USB devices
„
Small package and footprint saves board space
† 7×7 mm BGA, 84‐ball, RoHS compliant
† 12×12 mm LQFP, 100‐pin, RoHS compliant
„
16‐bit memory mapped interface can gluelessly interface to most
popular microprocessors and DSPs
„
Fast microprocessor access cycle and double/multi‐buffering
support for all four types of USB transfers
„
Two DMA (slave) channels for the high‐speed peripheral
controller, lowering CPU utilization
„
Integrated PLL supports external crystal or crystal oscillators of
12 MHz and 30 MHz, for system flexibility
„
16 Kbytes of on‐chip SRAM, optimized buffer size for
performance/cost
