Dallas Semiconductor Offers the World's Most Affordable 8051 Networked Microcontroller.Business Editors/High-Tech Writers DALLAS--(BUSINESS WIRE)--Nov. 4, 2002 Dallas Semiconductor (Nasdaq:MXIM) introduces the DS80C400, a networked microcontroller chip that integrates a high-speed 8051 core, a 10/100Mb Ethernet MAC, and silicon software TCP IPv4/v6 stack. The DS80C400 can be connected directly to IP networks and costs less than $9.00, making it the most affordable solution for your embedded networking needs. Operating at up to 75MHz, the DS80C400 provides ample speed to perform local control while also servicing network requests. In addition to the Ethernet MAC, the DS80C400 includes three synchronous/asynchronous serial ports that operate up to 18.75Mbps, a CAN2.0B controller, up to eight ports (64 I/O pins), and a 1-Wire(R) master. Applications that require network connectivity such as MP3 audio players, web cameras, environmental controls, and industrial equipment can use the DS80C400's network interface for data collection, remote monitoring and control as well as remote application updates. The resident silicon software on the chip supports Internet standards such as TCP, UDP UDP (uridine diphosphate): see uracil. (User Datagram Protocol) A protocol within the TCP/IP protocol suite that is used in place of TCP when a reliable delivery is not required. , IPv4/v6, IGMP (Internet Group Multicast Protocol) The protocol that governs the management of multicast groups in a TCP/IP network. To sign up for a multicast group, a Host Membership Report is sent by a user's machine to its nearest routers, which forward that data to , ICMP (Internet Control Message Protocol) A TCP/IP protocol used to send error and control messages. For example, a router uses ICMP to notify the sender that its destination node is not available. , TFTP (Trivial File Transfer Protocol) A lightweight version of the FTP protocol that has no directory browsing or password capability. Employing UDP rather than TCP for transport, TFTP is typically used to transfer firmware upgrades to network equipment such as , and DHCP (Dynamic Host Configuration Protocol) Software that automatically assigns temporary IP addresses to client stations logging into an IP network. It eliminates having to manually assign permanent "static" IP addresses. DHCP software runs in servers and routers. . Applications can be executed from local memory or downloaded from the Internet for quick application updates. Build an embedded web server Web server software embedded within a hardware device such as a print server. It is widely used in a myriad of devices, because it allows access to the software via any Web browser, typically for configuring the device or obtaining reports.

A free download of the Tiny Internet Interface The Tiny Internet Interface or TINI for short, is a microcontroller that includes the facilities necessary to connect to the Internet. The TINI platform is a microcontroller-based development platform that executes code for embedded web servers. (TINI(R)) runtime environment is available at www.maxim-ic.com/TINI. The DSTINIm400-144 verification module is also available for developers who want a proven implementation of the reference design for rapid evaluation and system integration. To streamline access to the network, application code can be written in Java(TM) or C. Visit the Maxim/Dallas Microcontrollers' website at www.maxim-ic.com/microcontrollers for reference design schematics and an interactive demonstration. The DS80C400 is available in a 100-pin LQFP. Prices start at less than $9.00 (1000-up, FOB USA). Dallas Semiconductor is a wholly owned subsidiary Wholly Owned Subsidiary A subsidiary whose parent company owns 100% of its common stock.
