Universal Serial Bus (USB) interface is now well established as an interface for computer data communications. In many areas it has completely overtaken other forms of serial or parallel interfaces for computer peripherals and memory storage devices. Advantages of USB are its flexibility, reasonably fast serial data transfer rate, simple 4 wire interface, and its ability to obtain power through the connector. The uses for USB storage devices continue to expand.Small 2x5 internal USB interface headers are now found on many computer motherboards and embedded system hardware. Because of the USB’s small size and simple interface they will find more and more use in compact, embedded, and mobile systems. Swissbit provides both internal and external USB solutions with up to 8GB capacity to address a variety of commercial and industrial applications. Swissbit offers most USB products in commercial, extended, and industrial operating temperature ranges.
