Actel Delivers Radiation-Tolerant, High-Density FPGAs Optimized for Space Applications

Samples of New RTAX-S Devices Now Shipping to Customers; Design and Prototyping Support Available Immediately

MOUNTAIN VIEW, Calif., July 6, 2004 - Actel Corporation (Nasdaq: ACTL) today announced the availability of engineering samples for all three devices in its high-density RTAX-S family of radiation-tolerant field-programmable gate arrays (FPGAs). The RTAX250S, RTAX1000S and RTAX2000S devices offer high-performance single-chip solutions to the space-flight market, primarily for use in satellite bus and payload applications. Additionally, Actel's new Libero 6.0 Integrated Design Environment (IDE), featuring design automation tools from Actel and leading EDA vendors, offers full support for all three devices in the RTAX-S family.

"Delivery as promised of our RTAX-S family of FPGAs gives aerospace engineers a high-density, high-performance alternative to the costly and time-consuming ASIC design cycle traditionally available to designers of space applications," said Ken O'Neill, director of marketing for military and aerospace products at Actel. "With gate counts up to five times higher than our previous space-flight FPGAs, and architectural enhancements and I/Os that improve performance, the radiation-tolerant RTAX-S devices meet the uncompromising demands of space applications."

The devices in the RTAX-S family offer increased performance through architectural enhancements that improve arithmetic functions. Additionally, the family incorporates single-event upset (SEU) hardened flip-flops, providing a cost-sensitive design solution by eliminating the need to implement triple-module redundancy (TMR). The embedded SRAM used on the RTAX-S devices is also optimized for use in harsh space environments thanks to error detection and correction (EDAC) IP and an integrated SRAM scrubber.

Taking the guesswork out of FPGA design, Actel offers a comprehensive suite of design tools optimized for the RTAX-S devices. The Libero 6.0 IDE includes best-in-class tools from Mentor Graphics, Magma Design Automation, SynaptiCAD and Synplicity, integrated into a single FPGA development package with custom-developed tools from Actel. The IDE offers a powerful design manager that keeps track of design files and seamlessly manages the interoperability issues typically associated with using tools from multiple vendors. With today's announcement, Actel also offers complete prototyping support for the RTAX-S devices.

The RTAX2000S offers two million equivalent system gates (250,000 ASIC gates) and 288K of core RAM. The RTAX1000S features one million equivalent system gates (125,000 ASIC gates) and 162K of core RAM. The third device in the family, the RTAX250S offers 250,000 equivalent system gates (30,000 ASIC gates) and 54K of core RAM.

Pricing and Availability

Engineering samples of the RTAX250S, RTAX1000S and RTAX2000S are available now. Pricing for devices in the RTAX-S family begin at $3,980 each in 25-unit quantities. For more information on pricing and availability, please contact Actel.
