NEC Electronics has introduced the world's first Universal Serial Bus (USB) host controller for the new SuperSpeed USB 3.0 standard. NEC Electronics expects rapid adoption of the device and standard as the need to transfer larger and larger amounts of information between PCs to external hard-drives, portable electronics devices, and flash-based thumb drives, continues to grow rapidly.

The host controller for PCs and other digital devices is based on the new version of the SuperSpeed USB standard. Supporting the world's fastest USB transfer speeds of up to 5 gigabits per second (Gbps) of data, which is 10 times faster than previous USB 2.0 transfer speeds. The NEC Electronics device, as well as the standard, is fully backward compatible with the USB 2.0, 1.1 and 1.0 versions of the USB standard.

With its high-speed transfer capability, the USB 3.0 host controller makes it possible to expand the boundaries of digital appliances such as PCs, digital TVs, and DVD recorders. The new SuperSpeed USB 3.0 chip from NEC Electronics requires only 70 seconds to transfer 25 GB of video content on a blu-ray disc, compared to 14 minutes to transfer the same content when using the high-speed USB 2.0 with 480 Mbps transfer capability. This enormous increase in transfer speed will enable system designers to transfer large-volume data quickly and without stress and develop a new generation of high-performance consumer electronic products.

The high data transfer rate also offers compatibility with recent high-performance computer interfaces such as PCI Express and SATA (Serial Advanced Technology Attachment), which are capable of data transfer at speeds in excess of 3 Gbps.

NEC Electronics expects the market for USB 3.0 products to begin a rapid expansion in 2010. It intends to market the new USB 3.0 controller aggressively, and to offer a range of related products by incorporating USB 3.0 communications as an IP (intellectual property) core function in various application specific ICs.
