RadiSys Integrates the Intel 815E Chipset and Pentium III in Its Low-Cost, High-Performance CompactPCI Building Block.

Business Editors/High-Tech Writers

HILLSBORO, Ore.--(BUSINESS WIRE)--May 21, 2001

RadiSys Corp. (Nasdaq:RSYS), a leading provider of building blocks enabling next-generation Internet and communications systems, today introduced the industry's first CompactPCI(R) system controller based on the embedded Intel(R) 815E chipset.

This latest RadiSys building block delivers OEMs both low cost and exceptional performance, for industrial automation, medical imaging and telecommunications applications, which require high-performance in a highly reliable system controller. Additionally, it is ideal for OEMs who need feature flexibility and a variety of I/O interfaces.

The Intel 815E chipset's built-in, high-performance AGP graphics and audio controller also makes RadiSys' latest building block well-suited to applications that require high-resolution 3D-graphics technology, such as robotics and medical imaging. Its integrated multimedia capabilities include AC '97 audio -- one of the only CompactPCI boards to offer this feature. This means an application that relies on a complex graphical user interface (GUI) and audible user feedback can be implemented in a CompactPCI-based system. Video is available as a conventional analog VGA interface or via the optional RTM, in DVI (PanelLink) format, allowing for longer distances between the computer and a high-resolution digital display.

Based on the Intel(R) Pentium(R) III processor -- supporting processor speeds from 600 to 866MHz and memory bus speeds of 100 and 133MHz -- this solution is designed to improve OEMs' time to market. Additionally, it can be expanded with an optional second-slot mezzanine board. Two mezzanine boards are currently available from RadiSys -- the MSF (multi-serial function board) and the MSIO (mass storage and I/O board) -- and RadiSys or the OEM can easily build customized versions.

To satisfy mass storage requirements, the system controller incorporates a dual EIDE controller and a standard floppy interface. A fast SCSI II interface is also available with the optional MSIO mezzanine adapter. When configured with either the optional MSF or MSIO mezzanine I/O cards, OEMs may select an on-board 2.5-inch hard disk drive or up to two on-board CompactFlash modules for mass storage. Directly mounted mass storage devices eliminate the need to cable outside the CompactPCI system platform, thus facilitating rapid, convenient and flexible product development. On-board peripherals also eliminate extraneous and unreliable connections to non-CompactPCI peripherals.

"This latest CompactPCI-based building block delivers the cost, performance, reliability and flexibility that our customers have come to expect," said Wade Clowes, vice president and general manager, RadiSys. "This is an ideal general-purpose solution for applications requiring front-panel and rear-panel I/O access, efficient use of system slots, and options for feature customization."

About the EPC-3325

The EPC-3325's passive heatsink design offers OEMs a higher mean time between failures (MTBF), when compared to fansink designs (which utilize an active heatsink). Additionally, the EPC-3325 includes ruggedized non-rotating mass storage (CompactFlash) and an optional SCSI II interface for 24 x 7 operation of 3.5-inch hard disks.

The EPC-3325 features one 144-pin SODIMM socket that supports up to 256MB of SDRAM. An additional 256MB of soldered-down SDRAM accommodates a total of 512MB of SDRAM. The EPC-3325 offers a full set of standard I/O interfaces accessible from the front panel or via an optional RTM (rear transition module). I/O interfaces include a PMC slot; dual 10/100BaseTX Ethernet interfaces; four USB ports; dual serial ports (six serial ports with the optional MSF mezzanine); a parallel port; a PS/2 keyboard/mouse; and both analog and digital (DVI) video. Additionally, RadiSys' latest building block has a real-time clock with an on-board battery, dual EIDE interfaces, and a floppy interface.

The EPC-3325 comes with a two-year warranty and is currently available in limited quantities. Full production is scheduled for September 2001. Pricing, which starts at $1,800, depends on exact configuration.
