The Oxford Semiconductor OXU121HP (formerly TD1120) is a singleâ
chip USB OnâTheâGo (OTG) controller that incorporates a fullâspeed host
and a highâspeed peripheral controller. It enables an embedded system
to operate as a USB host and a peripheral simultaneously, thereby
dramatically expanding the degree of interconnectivity and extending
the applicability of USB into many new areas, especially in mobile
communication, consumer electronics, and printer applications. The
combination of the OXU121HP highâspeed peripheral and fullâspeed
host controller enables users to perform highâspeed USB data transfer for
peripheral connectivity when connected to a host device, and operate at
full speed in host mode operation to maximize system battery life in a
mobile environment.
The OXU121HP is ideal for mobile applications. It enables highâspeed
PC synchronization to reduce data file transfer time when operating in
USB peripheral mode. In host mode, it enables the system to connect to a
wide range of USB devices such as flash drives, keyboards, mice, and
digital still cameras (DSC). These mobile applications include smart
phones, PDAs, MP3 players, portable media players, digital photo
albums, and GPS devices.
The OXU121HP is well suited for PictBridge printers. It enables highâ
speed data transfer between PC and printer. While utilizing the host
port, it adds PictBridge printing capability to the printer to support
direct photo printing from a DSC. The OXU121HP replaces existing twoâ
chip solutions by combining discrete host and peripheral controllers into
a single chip, thus minimizing system cost, board space, design
complexity, and power consumption.
The OXU121HP allows for simultaneous host and peripheral operation.
The ports can be configured in one of two modes:
Â
1 OTG + 1 Host: one OTG port and one fullâspeed host port
Â
1 Peripheral + 2 Host: one highâspeed peripheral port and two
fullâspeed host ports
Software solutions for the OXU121HP include USB device drivers and
the Oxford Semiconductor USBLinkTM product suite. The USBLink host,
