Toshiba announced it will launch a single chip IC that is compliant with the TransferJet standard for close proximity wireless transfer technology. Samples will start shipping at the end of January 2012 and mass production is scheduled to begin in the second quarter (April-June) of 2012.
Using Toshiba’s cutting-edge wireless communication technology, the new product achieves receiving sensitivity of -78dBm, the best performance in the industry, greatly surpassing the requirements of the TransferJetTM specification [1]. This high sensitivity contributes to stable communication between TransferJetTM-compliant digital devices.

Toshiba’s advanced RF-CMOS integration technology has enabled incorporation of an RF circuit and RF switch for TransferJetTM in a wireless IC for the first time in the industry. Utilizing the 65nm process, Toshiba has not only reduced the chip size and realized the smallest package in the industry but also decreased the number of external RF circuits and peripheral components required. This makes the new product particularly well-suited for increasingly compact and lightweight digital products, such as smartphones, tablet PCs, notebook PCs, and digital cameras.

Background and objectives
The spread of smartphones, digital cameras, tablet PCs and other mobile products is spurring demand for simple yet high-speed ways of sharing large image, video, and audio data among individuals. Toshiba is addressing this demand by launching a wireless IC compliant with the TransferJetTM standard for close proximity wireless transfer technology that allows data transfer simply by selecting on the screen of a mobile device the data file to be transferred and “touching” the receiving device with the mobile device.

What is TransferJetTM?
TransferJetTM is a close proximity wireless transfer technology standard promoted by the TransferJetTM Consortium whose membership consists of 53 companies (as of September 2011), including Toshiba. High-speed data transfer at low power consumption is available simply by selecting on the screen of a mobile device the data file to be transferred and “touching” the receiving device with the mobile device. TransferJet has a maximum specified transmission rate of 560 Mbit/s and maximum effective rate of 375 Mbit/s. Application of TransferJetTM will be expanded with digital signage and through linkage with NFC (Near Field Communications) technology.
