USB 3.0 compliant control unit on NEC expansion cards
The NEC has placed a USB 3.0 controller on its expansion cards.
The USB Implementers Forum, responsible for maintaining the Universal Serial Bus standard, is attended by giants such as Apple Computer, Hewlett-Packard, Microsoft, Intel, Agere Systems and NEC. The backward compatible USB 3.0 is complete In November 2008 announced USB-IF, which enables significantly higher data transfer speeds in line with the needs of our time: while the theoretical bandwidth of USB 1.0 has been maximized at 1,5, that of USB 1.1 at 12, and that of USB 2.0 at 480 Mbit / s, USB 3.0 is capable of 5,0 Gbit / s.
To promote the next-generation standard, NEC has introduced expansion cards with a USB 3.0-compliant control unit called the µPD720200 chip. One can be inserted into a PCI Express x1 slot and the other into an ExpressCard slot on laptops, both offering two USB ports, and in terms of the purchase price of the products, are expected to be around $ 15-20.
