Actel Receives DSCC SMD; Achieves New Quality Milestone for RTAX-S FPGAs

Company Announces Plans to Add QML-V Flow for Space-Optimized Family

MOUNTAIN VIEW, Calif. -- April 24, 2006 -- Actel Corporation (Nasdaq: ACTL) today announced that Defense Supplier Center Columbus (DSCC) has released Standard Microcircuit Drawing (SMD) numbers for Actel's high-reliability, radiation-tolerant RTAX2000S, RTAX1000S and RTAX250S devices. Signaling compliance with the Department of Defense's MIL-PRF-38535 performance standard, designers can utilize SMD numbers to specify the high-performance field-programmable gate arrays (FPGAs) for their space-flight applications. The SMD release, a key industry recognition of high quality, enables designers to more easily procure and utilize the high-performance RTAX-S devices in their space technology designs and across all DoD programs.

Today, Actel also announced that it is pursuing QML class V certification for the RTAX-S family. The highest level of screening for space parts within the QML program, class V certification verifies that quality processes and qualification data have been examined and approved by DSCC, SMC and NASA. Actel is working to implement the screening process by the end of 2006 and plans to have QML-V certified RTAX-S product availability by the end of 2007.

"By achieving compliance with stringent DSCC and DoD requirements, we can assure our customers that we take seriously the industry's measures of the highest quality for high-reliability, radiation-tolerant FPGAs," said Ravi Pragasam, senior manager of military and aerospace product marketing at Actel. "We also recognize our customers' desire for QML-V certification for our popular high-performance RTAX-S family; therefore, we are taking the necessary steps to deliver this to the space market, a further demonstration of our commitment to these customers."

About the RTAX-S Family

Designed to withstand the rigors of space-flight applications, the Actel radiation-tolerant RTAX-S FPGA family consists of devices ranging in density from 250,000 to 4-million equivalent system gates. The family offers unique features, such as Single-Event Upset (SEU)-hardened flip-flops, usable error-corrected on-board memory and a large number of user I/O, desirable for space-flight applications. These, in combination with the inherent benefits of Actel's nonvolatile products, give designers the ability to reduce component count, minimize power consumption and save board space and weight while meeting their density, performance and radiation-resistance requirements.
