Business Editors/High Tech Writers

CAMPBELL, Calif.--(BUSINESS WIRE)--Sept. 5, 2000

ZiLOG Inc. (formerly ZLG on the NYSE), the Extreme Connectivity company, today announced an Embedded Webserver Software Suite that runs on its Z180 8-bit microprocessor family, including its newest member, the Z80S183. The Embedded Webserver Software Suite is the industry's first solution to implement full-featured Internet protocol stacks enabling 8-bit microprocessors to access the Internet.

"ZiLOG reinvented its popular Z180 family for the Net Economy by providing a software solution that is scalable and fully compliant with today's Internet protocol standards," said Daryl RuDusky, vice president of ZiLOG's Internet Processor Division. "Customers are under pressure to improve their time-to-market. We provide the silicon and software solution in one bundled package so that customers no longer need to purchase connectivity capability in pieces from multiple suppliers."

The webserver software suite enables Z180 customers to leverage the Internet without migrating to a 16- or 32-bit platform. Unlike other 8-bit solutions, ZiLOG's suite adheres to the standards defined by groups such as the Internet Engineering Task Force (IETF) and the World Wide Web Consortium (W3C).

The webserver software suite operates on ZiLOG's Z180 family, which delivers the addressing space (1 Mbyte) and processing power (33 MHz) to incorporate all of the protocols necessary to access the Internet. The Z180 is an 8-bit processor utilizing 8-bit peripherals, tools and memory, thus reducing system-level costs.

ZiLOG's Z180 family when combined with the software suite addresses all three criteria that embedded customers require for their Internet-enabled applications:

-- Software Available October 2000

-- Silicon Available now

The Z80S183 processor allows customers to implement an embedded webserver that supports analog and digital data streams for Internet connectivity. For Z80S183 features see: www.zilog.com/newprod/z80s183.html

The Z180 family provides the bandwidth necessary to perform the complicated tasks of today's command, control and Internet protocol processing. The hardware and solution is designed for applications such as industrial control, factory automation, remote monitoring, electronic transactions and other command and control functions communicating via local and wide area networks. Traditionally, companies have relied on proprietary protocols to conduct remote command and control. As devices become more connected, standard protocols will be critical to ensure compliance, interoperability and long-term connectivity access.

"Compliance to globally accepted Internet standards are critical to the long-term success of customers. Our customers recognize that full compliance enables them to sustain communications as the Internet evolves," said Danny Chi, business line manager for ZiLOG's Internet Processor Division.

ZiLOG is offering the Embedded Webserver Software Suite for all of its Z180-based family. The newest member of the Z180 family, the Z80S183, sells for $15 in 1,000-piece quantities.
