As a result of the growing need for such mobile devices to communicate directly with each other when a PC is not available, the Universal Serial Bus Implementers Forum (USB-IF) released the new USB OTG standard supplement for vendors last December.

The company plans to start mass producing the chip from September. The sample price is expected to be
