                             FACT SHEET

PRODUCT NAMES:   DECchip 21066 166 MHz Microprocessor
                 DECchip 21068 66 MHz Microprocessor


The DECchip 21066 and DECchip 21068 microprocessors are highly 
integrated, high-speed microprocessors that implement Digital's 
Alpha AXP architecture.  The new processors incorporate on-chip the 
industry-standard Peripheral Component Interface (PCI) bus as the 
primary I/O.  In addition, key functions such as a memory 
controller, graphics accelerator, and phase-locked loop clock have 
been integrated into the design.  Both microprocessors are pin 
compatible, .68 micron CMOS-based superscalar, superpipelined 

The DECchip 21066 microprocessor brings the high performance of 
Digital's Alpha AXP 64-bit Reduced Instruction Set Computer (RISC) 
architecture to the Windows NT PC market.  This 166 MHz processor 
provides Windows NT PC system vendors with the technology to deliver 
superior performance (estimated 70 SPECint92, 105 SPECfp92) at 
competitive market prices.  The chip's high integration technology 
simplifies PC system design, reduces overall system cost, and 
provides access to industry-standard, off-the shelf peripherals.   

The DECchip 21068 microprocessor provides industrial single-board 
computer and high-end embedded application vendors with an estimated 
70 Dhrystone MIPS at 66 MHz and only 8.5 Watts of power dissipation.  
Pin compatibility with the DECchip 21066 provides ample room for 
performance growth by extending the usefulness of software developed 
for DECchip 21068 microprocessors.  Digital's competitive, high-
performance Alpha AXP DEC 3000 workstations, combined with the CASE 
tool DEC FUSE, and the DECchip 21066/21068 Evaluation Board provide 
a native software development environment that will streamline the 
coding and debugging of software.
