USB On-The-Go Full-Speed Host and High-Speed
Peripheral Controller
Features
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
