100 BaseT USB 2.0-Ethernet Controller Provides 40 Times Faster USB Connections; Now Available from Kawasaki LSI.Business/High-Tech Editors SAN JOSE, Calif.--(BUSINESS WIRE)--Nov. 6, 2000 Controller Enables Remote Network Device Interface Specification (networking, hardware, standard) Network Device Interface Specification - (NDIS) A Microsoft Windows device driver programming interface allowing multiple protocols to share the same network hardware. E.g. TCP/IP and IPX on the same NIC. NDIS can also be used by some ISDN adapters. (NDIS (Network Driver Interface Specification) A network driver interface from Microsoft. See network driver interface. NDIS - Network Device Interface Specification ) in USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. 2.0 and True 10/100 BaseT Environments Kawasaki LSI LSI: see integrated circuit. (Large Scale Integration) Between 3,000 and 100,000 transistors on a chip. See SSI, MSI, VLSI and ULSI. , U.S.A., the USB controller company, allows an easy interface between 100 BaseT Ethernet and the new USB 2.0 (480Mb/sec.) specification with its KL5KUSB221. Designing the KL5KUSB221, which uses USB specification 2.0, into new laptop or mobile equipment devices takes full advantage of 100 BaseT network performance and converts USB 2.0 to Ethernet which is 10 times faster than traditional USB to Ethernet controllers based on version USB 1.0/1.1. Its MII physical layer interface allows for low-cost LAN (Local Area Network) A communications network that serves users within a confined geographical area. The "clients" are the user's workstations typically running Windows, although Mac and Linux clients are also used. and HAN (home area network) designs to be incorporated in portable equipment. The KL5KUSB221 has a highly integrated 16-bit RISC RISC in full Reduced Instruction Set Computing Computer architecture that uses a limited number of instructions. RISC became popular in microprocessors in the 1980s. CPU CPU in full central processing unit Principal component of a digital computer, composed of a control unit, an instruction-decoding unit, and an arithmetic-logic unit. , mask ROM and RAM buffer, clock generator, Ethernet interface, UART (Universal Asynchronous Receiver Transmitter) The electronic circuit that makes up the serial port. Also known as "universal serial asynchronous receiver transmitter" (USART), it converts parallel bytes from the CPU into serial bits for transmission, and vice , IRQ, watchdog timer, serial interface and external memory and SPORT interfaces. System designers can use the KL5KUSB221's remote NDIS when designing end devices for connection to LAN, HAN or cable modems. Kawasaki LSI designed the KL5KUSB221's internal processor to enable remote network device interface specifications (NDIS) that are compatible with current and next-generation operating systems. Its serial interface engine (SIE) is compatible with all USB specifications. Although designed specifically for USB 2.0 to 100 BaseT networking, the KL5KUSB221 is also legacy compatible with 1.1 interface connections and compatible with 10 BaseT Ethernet networking. The KL5KUSB221 standardized Remote NDIS feature requires only one set of drivers to support multiple bus-attached network devices. For the system designer, incorporating Remote NDIS such as that in the KL5KUSB221 improves overall stability of a system as well as enhanced performance speeds of the network interface system. The KL5KUSB221 is housed in a 100-pin QFP package and priced at $11.00 each in 1,000 unit volumes. Evaluation boards and reference designs are available. Drivers are included and source code is available for a licensing fee. Kawasaki LSI U.S.A. is the North American affiliate of Kawasaki LSI, which in turn is a division of Kawasaki Steel in Japan. The company provides the product development, marketing, sales and technical support for customers in the Americas in connectivity and data communications applications. |
