DIGITAL INTRODUCES PCI-BASED SYSTEM LOGIC CHIPSETS FOR ALPHA AXP 21064 MICROPROCESSORS; ANNOUNCES THE INDUSTRY'S FIRST PCI TO PCI BRIDGE CHIP

 Digital expands commitment to merchant semiconductor market
 MAYNARD, Mass., Jan. 10 /PRNewswire/ -- Digital Equipment Corporation (NYSE: DEC) today announced the DECchip 21071 and DECchip 21072 PCI-based system logic chipsets for Digital's Alpha AXP 21064 microprocessor family. Digital also augmented its portfolio of Peripheral Component Interconnect (PCI)-based products with the announcement of the industry's first PCI to PCI bridge chip, the DECchip 21050 bridge chip. The DECchip 21050 bridge chip greatly expands the performance capabilities of PCI-based systems, including systems based on Alpha AXP, i486 and Pentium microprocessors.
 "With the announcement of chipsets for the Alpha AXP 21064 microprocessor family, we are enabling manufacturers to build workstation-class computers at PC prices," said Ed Caldwell, vice president, Semiconductor Operations, Digital Equipment Corporation. "We are reaffirming our commitment to the merchant vendor market and to the PCI bus standard," Caldwell continued, "and we will continue to expand our family of PCI-based peripheral chips to satisfy the emerging PCI market."
 The market research firm Dataquest, Inc., expects 10.2 million PCI-based systems to ship in 1994, growing to 31.2 million in 1995. By standardizing on PCI, system manufacturers are able to use high- volume, low-cost components and protect their investments in PCI peripherals across multiple architectures and microprocessor generations.
 More than 200 leading semiconductor and computer vendors support the PCI bus standard. Digital is a founding member of the PCI Special Interest Group (SIG) and has already introduced the industry's first microprocessors featuring an integrated PCI interface, the DECchip 21066 and 21068 microprocessors, which are members of the Alpha AXP microprocessor family, as well as the DECchip 21040 network controller, the industry's first PCI-based Ethernet controller.
 DECchip 21071 and DECchip 21072 System Logic Chipsets
 The DECchip 21071 system logic chipset is a 4-chip implementation that incorporates a memory controller, PCI interface, and 2 datapath chips. It offers a 64-bit-wide memory path and is priced at $90 in quantities of 5,000. The 21071 chipset gives system manufacturers an ideal design solution for cost-sensitive PC systems.
 Featuring a 128-bit-wide memory path and error correction code (ECC), the 6-chip DECchip 21072 chipset provides the very high performance and reliability needed in server and high-end desktop systems. It is priced at $140 in quantities of 5,000.
 "The DECchip 21072 chipset allows us to quickly design high performance 21064 microprocessor-based systems," said Rod Frye, co-founder of Carrera Computers. "Our Panterra family of systems, which utilizes the DECchip 21072 chipset, takes advantage of the highest performance Alpha AXP microprocessors, which makes Windows NT fly."
 Designed to work with any DECchip 21064 microprocessor, from the 21064-150 MHz microprocessor to the 21064A-275 MHz micro-processor, these chipsets enable system manufacturers to build a wide range of uniprocessor PCI-based systems faster and at lower cost. Samples are available now for both products, with volume expected in the second quarter of calendar year 1994.
 "With this announcement, Digital now offers a full range of CPU/system logic performance capabilities, from the very low-cost 21066-166 MHz microprocessor, featuring on-chip system logic, to the highest performance 21064A-275 MHz microprocessor combined with 21072 system logic chipset," said Art Swift, Digital's Semiconductor Marketing and Sales Group Manager.
 DECchip 21050 PCI to PCI Bridge
 "The PCI-PCI bridge chip is them most important piece of silicon in the industry," said Alan Deikman, CEO of Znyx. "It is an enabling technology, allowing us to expand the PCI bus into multi-function cards and into systems that can be configured far beyond what is possible with prior technologies." Znyx, a LAN products manufacturer headquartered in Fremont, Calif., has developed its ZX314 multi-port PCI Ethernet Adapter using the DECchip 21050 PCI-PCI bridge. Deikman further said, "Anyone who does not believe that PCI is the bus and architecture of the future has not examined what Digital's PCI-PCI bridge chip can do." Compliant with PCI revision 2.0, the DECchip 21050 bridge chip enables the configuration of multiple hierarchical PCI buses on a system, permitting more robust system designs that offer capabilities beyond those permitted by a single PCI bus.
 Using the DECchip 21050 bridge chip, system manufacturers can configure enough PCI-based components and option slots to satisfy any system requirement. With multiple PCI to PCI bridge chips, servers having as many as 32 PCI option slots can be configured. Further, they can support multiple components, as in a quad Ethernet board or a multimedia card, on a single PCI-based expansion card.
 "The server market needs a solution to the slot limitation of current PCI designs. Any product that expands PCI beyond the typical two slots is apt to find a ready market," said Dean McCarron, principal, Mercury Research.
 Packaged in a standard 5-volt 208-pin plastic quad flat pack (PQFP), the DECchip 21050 bridge chip is priced at $22.80 in quantities of 5,000, and will be available in volume in the second quarter of calendar year 1994. Samples are available now.
 Evaluation Board Kits Expedite System Design and Development
 The 21064 microprocessor PCI Evaluation Board (EB64+ board) is a tool that enables hardware engineers to design 21064 microprocessor- based products using the DECchip 21071 or 21072 system logic chipsets easily and quickly. The Evaluation Board Kit includes an example design of an Alpha AXP motherboard plus supporting example files, source code, and simulation database, and provides a platform for benchmarking and software debugging. The Evaluation Board Kit will be available for $5,000 in the first quarter of calendar year 1994.
 Digital Equipment Corporation is the world's leader in open client/server solutions from personal computing to integrated worldwide information systems. Digital's Alpha AXP platforms, storage, networking, software and services, together with industry-focused solutions from business partners, help organizations compete and win in today's global marketplace.
