Upgraded performance for USB On-The-Go

The OTG242LP has the smallest footprint of any USB OTG controller on the market and sets a new standard in power consumption with a 50% decrease over competitive OTG controllers.

The OTG242LP has the smallest footprint of any USB OTG controller on the market and sets a new standard in power consumption with a 50% decrease over competitive OTG controllers.

"The USB OTG specification was created specifically for mobile devices, allowing them to connect directly to one another without the aid of a PC, through the popular, and readily available, USB standard", said David Murray Vice President of Marketing for TransDimension.

"Now there is an OTG controller that is ideally suited for mobile applications where low power and a very small footprint are absolutely essential".

The new controller is available in a 64-pin QFP or 5 x 5mm micro BGA package.

It consumes as little as 20mA during operation, yet offers uncompromising performance.

Based on the same high performance architecture as TransDimension's first, market leading, OTG controller (OTG243), the OTG242LP enables high USB throughput while keeping CPU utilisation at a minimum.

One of the most significant capabilities enabled by the USB OTG specification is the ability for products, traditionally used as PC peripherals, to act as a host.

These products, including printers, digital cameras, and PDAs, can now transfer data on their own.

Literally hundreds of different USB peripherals may be plugged in to a USB OTG port.

The OTG242LP is supported by SoftConnex's OTG software, USBLink OTG.

SoftConnex is a wholly owned subsidiary of TransDimension and has developed USB protocol stacks and host controller drivers for 16 different operating systems including WinCE, Linux, Symbian, VxWorks, Nucleus and Itron.

SoftConnex also supports the largest library of class drivers in the industry for nearly all USB device classes as well as many proprietary device drivers.

Using SoftConnex software, a manufacturer adopting TransDimension's OTG242LP can achieve quick time to market on a proven, robust software platform.

The OTG242LP has two ports, one dedicated host port and another port that can operate as a host port, a peripheral port, or an OTG port.

It has a 16bit memory bus, which can interface with most microprocessors.

All transceivers and pull-up resistors are integrated and a pin to switch an external 5V power supply is included.

The variable I/O interface can run at 2.5 to 3.3V from a single 3.3V power supply.
