Design Engineers Applaud New ZiLOG TCP/IP Stack for Ease of Implementation and Reliability.Business Editors/High-Tech Writers SAN JOSE, Calif.--(BUSINESS WIRE)--Aug. 18, 2003 ZiLOG, Inc. (OTCBB OTCBB See OTC Bulletin Board (OTCBB). :ZILG) Royalty-free, scalable protocol stack solidifies ZiLOG's position as a leading embedded 8-bit network solution provider ZiLOG, Inc. (OTCBB:ZILG), the creator of the Z80 microprocessor and a leading innovator of integrated 8-bit microcontroller solutions, today announced the release of its own royalty-free, full-featured TCP/IP TCP/IP in full Transmission Control Protocol/Internet Protocol Standard Internet communications protocols that allow digital computers to communicate over long distances. protocol stack for the eZ80Acclaim!(TM) product family and all ZiLOG eZ80 microprocessor platforms. ZiLOG's scalable architecture provides a full range of Ethernet features for small to large applications without performance degradation. The TCP/IP protocol stack is loaded into Flash memory, ensuring flexibility and easy upgrading as ZiLOG continues to improve its embedded networking implementation. The new protocol stack gives design engineers direct access to standard networking technology that's both scalable and interoperable on the Internet. Enhanced API documentation and sample code simplify engineering integration. The stack makes components such as ZiLOG's award-winning eZ80Acclaim! family of high-performance microcontrollers ideal for the Global Packet Radio Service (GPRS (General Packet Radio Service) The first high-speed digital data service provided by cellular carriers that used the GSM technology. GPRS added a packet-switched channel to GSM, which uses dedicated, circuit-switched channels for voice conversations. ) market, and for both wired and wireless Ethernet-based remote access and control applications. "This new TCP/IP stack is just the next step in ZiLOG's efforts to provide a full-featured 8-bit network solution that includes silicon, protocol software and development tools," said Michael Gershowitz, Director of Product Marketing for Microcontrollers at ZiLOG. "This new TCP/IP stack, which includes a dedicated technical support line for the software, underlines ZiLOG's ongoing commitment to providing a comprehensive and scalable toolset to its customers." The ZiLOG TCP/IP protocol stack enables design engineers to build high-performance embedded networking products at very low cost. The new protocol stack supports 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. , IP, ARP, RARP (Reverse ARP) A TCP/IP protocol used by a diskless workstation to obtain its IP address. Upon startup, the client station sends out a RARP request in an Ethernet frame to the RARP server, which returns the layer 3 address for a layer 2 address (performing the opposite , 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. , 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 , PPP (Point-to-Point Protocol) The most popular method for transporting IP packets over a serial link between the user and the ISP. Developed in 1994 by the IETF and superseding the SLIP protocol, PPP establishes the session between the user's computer and the ISP using , Ethernet, HTTP HTTP in full HyperText Transfer Protocol Standard application-level protocol used for exchanging files on the World Wide Web. HTTP runs on top of the TCP/IP protocol. , SMTP (Simple Mail Transfer Protocol) The standard e-mail protocol on the Internet and part of the TCP/IP protocol suite, as defined by IETF RFC 2821. SMTP defines the message format and the message transfer agent (MTA), which stores and forwards the mail. , DHCP/BOOTP, SNMP (Simple Network Management Protocol) A widely used network monitoring and control protocol. Data are passed from SNMP agents, which are hardware and/or software processes reporting activity in each network device (hub, router, bridge, etc. , TFTP, TELNET, and TIMEP protocols. It includes enhancements such as SNMPv1 support and other user-extensible MIBs. Registered ZiLOG customers can download it for free directly from ZiLOG's Web site. The new protocol stack is backward-compatible with ZiLOG's previous TCP/IP software. About eZ80Acclaim!
