DIGITAL'S NEW ALPHA 21066A CHIP WITH PCI PUTS MORE
SPEED INTO EMBEDDED APPLICATIONS, DESKTOP PCs
MAYNARD, Mass. -- November 14, 1994 -- Digital Equipment Corporation today
announced a new, 0.50-micron version of its Alpha 21066 microprocessor. The
Alpha 21066A chip features increased speed for faster realtime response in high-
-end embedded applications and higher performance in desktop applications. It is
the latest of Digital Semiconductor's highly integrated microprocessors
containing the industry's first on-chip implementation of the PCI (Peripheral
Component Interconnect) bus.
"The new, 233MHz Alpha 21066A chip enables us to put the power of the Alpha
architecture into embedded, realtime control systems with more performance than
ever," said Tim Miller, Digital Semiconductor's marketing manager for Alpha
Microprocessors. "For the Windows NT desktop market, the highly integrated
design with PCI greatly simplifies the task of building low-cost RISC PCs. We
are well positioned for this market, with more than 750 native-mode Windows NT
applications shipping for Alpha systems and over 1,400 additional committed
Miller added that Digital is an acknowledged leader in PCI technology, and that
in addition to PCI support for all Alpha microprocessors, Digital Semiconductor
offers a family of PCI peripheral products for Fast Ethernet and Ethernet
networking, graphics, and PCI-to-PCI bridging.
Like its predecessor, the Alpha 21066A contains an integrated on-chip memory
controller and graphics accelerator in addition to the PCI interface. These
features can substantially reduce the cost of system implementations based on
the Alpha 21066A and provide an easy link to inexpensive, off-the-shelf memory
and peripheral devices. The integrated, richly functional design makes the
product especially useful for high-performance, small-form-factor applications.
The new chip also features programmable, software-controlled power management,
which can vastly reduce power consumption during periods of inactivity and help
qualify systems for Energy Star certification.
More Power for Embedded Applications
The Alpha 21066A microprocessor is the latest and most powerful in a family of
highly integrated chips for high-end embedded applications. The chip has been
chosen by Prime Option, Inc., as a controller for high-end print engines. It
will be used by Alpha Data Parallel Systems Ltd. in PC and workstation
accelerator platforms and as building blocks for parallel processing systems, as
well as by Alta Technology, Inc., in board-level, ATM (Asynchronous Transfer
Method)-linked parallel processors.
The Alpha 21066A chip also runs VxWorks for Alpha software, a realtime operating
system adapted from Wind River Systems' VxWorks application development and
runtime system. VxWorks software is popular for developing and running embedded
applications such as network routers, RAID controllers, industrial process
controllers, and telecommunication cards.
The chip will be the heart of Digital's AXPvme series of VMEbus single-board
computers (SBCs), used by embedded-application OEMs and system designers in
control systems for many military and industrial realtime applications.
Choice for Desktop Systems
Like other members of Digital's Alpha microprocessor family, the new product
runs Digital's 64-bit DEC OSF/1 (UNIX) and OpenVMS operating systems in addition
to increasingly popular Windows NT software. The chip will power new models of
NekoTech's Mach 1 series of desktop PCs for the Windows NT market.
Digital Semiconductor also announced the new EB66+ Evaluation Board, which
provides a reference PCI and ISA motherboard design using the Alpha 21066A chip.
The EB66+ is intended as a starting point for new designs and as a platform for
parallel development of hardware and software applications. The board is
packaged with a user's manual, full layout and mechanical information, design
database, material lists, debug monitor, and firmware development tools.
The Alpha 21066A microprocessor is offered at two clock speeds: 100MHz and
233MHz. At 233 MHz it is estimated to deliver a SPECint92 rating of 94 and a
SPECfp92 rating of 110. Version 2.1 Dhrystone MIPS performance is 189.5 for the
233MHz version and 89.8 for the 100mhz version. The Alpha 21066A Chip is priced
at $175 for the 100MHz version and $360 for the 233MHz version in quantities of
5,000. Samples are available now.
Production of both the Alpha 21066A Chip and the EB66+ Evaluation Board is
scheduled for the first quarter of 1995.
