The TJM35420MU is the industry's first TransferJet™ microUSB adaptor module integrating a TransferJet™ transceiver IC, a coupler, an RF filter, peripheral passive parts, and a USB connection circuit. TransferJet™ communications can be implemented in Android™ devices2, such as smartphones and tablets, that have a microUSB port by inserting this module in the port and installing application software for Android™.

TransferJet™-enabled devices can transfer a one-minute high-definition movie in approximately three seconds3. TransferJet™ is expected to be widely adopted for smartphones, tablets, and various other devices. Toshiba will continue to develop and commercialize transceiver ICs and modules compliant with TransferJet™.

Toshiba will showcase, for reference, a tablet equipped with a prototype of this microUSB adaptor module, and a TransferJet™-enabled SDHC memory card, which is under development, at the 2013 International CES, the world's biggest consumer technology-related trade show, to be held from January 8 to 11, 2013, in Las Vegas, U.S.A.

2. Certain Android devices may not support TransferJet™.
3. For calculation, the capacity of a one-minute high-definition movie is assumed to be 128 MB.

Background and objectives

Demand is surging for simple yet high-speed sharing of large multimedia files, such as photos, movies, and audio data among individuals. In view of this demand, Toshiba has commercialize products, including a transceiver IC, a compact wireless module, a microSDIO card, and a USB adaptor module, that are compliant with the TransferJet™ standard for close proximity wireless transfer technology allowing data transfer just by touching two devices together. The latest addition to the line-up is a microUSB adaptor module that can be easily attached to smartphones and other mobile devices.

About TransferJet™

TransferJet™ is a close proximity wireless transfer technology standard promoted by the TransferJet™ Consortium whose membership consists of 45 companies (as of January 8, 2013), including Toshiba. TransferJet™ technology provides simple connection and high-speed data transfer with low power consumption just by selecting on the screen of a device the data file to be transferred and by touching the receiving device with that device. Applications of TransferJet™ technology is expected to expand when combined with various devices and technologies, such as digital signage and Near Field Communications (NFC).
