Date: 19970811 From: (DIGITAL PRESS RELEASE) Subject: PRESS/DIGITAL's Industry-Leading PCI-to-PCI Bridge Chips Marianne Mills (508) 568-5102 DIGITAL's Industry-Leading PCI-to-PCI Bridge Chips to Meet Power Management Specifications for 1998 PCs MAYNARD, Mass., August 11, 1997 - Digital Equipment Corporation announced today an enhanced version of its 21152 PCI-to-PCI bridge chip that complies with the Advanced Configuration Power Interface (ACPI) and PCI Bus Power Management Interface Specifications. Digital's industry-leading PCI-to-PCI bridge chips support power management and provide capabilities required for Microsoft certification for the next releases of the Microsoft Windows and Windows NT operating systems. "The power management-capable 21152 chip is now sampling. All remaining members of Digital Semiconductor's 2115x PCI-to-PCI bridge chip family will meet power management requirements for next-generation Windows compatibility within the next few months," said Matt Theall, PCI bridge products marketing manager, Digital Semiconductor, a Digital Equipment Corporation business. "Digital Semiconductor introduced the first Revision 2.0 and 2.1 PCI-to-PCI bridges. With this announcement, Digital continues to lead the industry in PCI bridges and to respond to customer needs for performance and compatibility for building future generations of systems," Theall added. Power Savings, Extended Capacity The ACPI and PCI Bus Power Management Interface Specifications enable operating system control rather than device control of power management, allowing greater flexibility and consistency in managing power reduction, removal, and restoration to system components. PCI-to-PCI bridge chips extend a system's I/O support capability by enabling motherboard designers to exceed the four-slot PCI bus limitation for PCI devices and option cards. Each PCI-to-PCI bridge chip added to the motherboard creates a new PCI bus to support additional PCI slots or devices. A PCI-to-PCI bridge also enables adapter card designers to overcome the single load limitation of the PCI Specification by providing an independent PCI bus on the adapter card, to which as many as nine devices can be added. Price, Availability The 21152 chip is priced at $13.90 in 1,000-unit quantities. Samples are being delivered now; volume shipments are scheduled for October 1997.
