Atmel's USB Hub Receives Microsoft Approval July 20, 1998 8:01 AM EDT SAN JOSE, Calif., July 20 /PRNewswire/ -- Atmel Corporation (Nasdaq: ATML) today announced that Microsoft Corporation (Nasdaq: MSFT) has approved its high-speed USB (Universal Serial Bus) hub controller and associated development kit, easing the way for system manufacturers that use Atmel's hub solution to display the Microsoft Windows (95 or 98) logos on their products. This is the first hub controller that has been approved for Windows use by the Microsoft Windows Hardware Quality Labs. The USB eases the connection of a wide range of individual computer peripherals to the main computer system, thus forging the way for true plug-and-play operation. Up to 127 peripherals can be supported by the USB system while eliminating the problems associated with a limited number of interrupts in personal computers. The Atmel AT43DK11 USB Hub Development Kit contains the AT43312 hub device, a PC board, various USB components, a power supply, cables, connectors and a box to build it in. Additionally, the development kit includes all of the appropriate design files and applications notes. The Atmel hub controller designed for USB use offers both self-powered and bus-powered operation. It provides one upstream port for connection to the host system, and four downstream ports for connecting to individual computer peripherals or additional hubs. In the self-powered mode, all USB compliant peripherals are supported. In the bus-powered mode, only low-power USB compliant devices can be connected to downstream ports. The 48 MHz clock required for the Atmel hub's operation is provided by an on-chip phase-lock loop that is driven by an external 6 MHz crystal. The use of the phase-lock loop not only reduces power dissipation, noise and the cost of the crystal, but it also eliminates the EMI shielding that is required for most applications using a crystal that produces a higher clock. Atmel's IC reduces system costs and is easier to design with. The Atmel AT43DK11 USB Hub Development Kit is priced at $395, and the hub itself, in a 32-pin SOIC or DIP, is priced at $2.40 each in quantities of 1,000 or more. Founded in 1984, Atmel Corporation is headquartered in San Jose, California with principal manufacturing facilities in Colorado Springs, Colorado, Nantes and Rousset, France and Heilbronn, Germany. Atmel designs, develops, manufactures and markets on a worldwide basis semiconductors, including nonvolatile and embedded memory, logic, analog, microcontroller products and system-level integration (SLI) solutions using advanced CMOS, BiCMOS, BiPolar and SiGe process technologies.
