Actel Corporation today announced it is shipping fully qualified RTAX-S field-programmable gate arrays (FPGAs) to customers developing high- reliability space-flight systems. The RTAX-S family ranges in density from 250,000 to two million equivalent system gates and meets the performance and radiation-resistance requirements of satellite bus and payload applications. The RTAX-S family offers sufficient density and features to enable designers to take advantage of the flexibility of FPGAs, thereby freeing designers from the front-end cost and schedule constraints that currently plague radiation-hardened application-specific integrated circuit (RH-ASIC) solutions. Further, unlike SRAM-based FPGAs, the single-chip RTAX250S, RTAX1000S and RTAX2000S devices have proven immunity to single-event upsets (SEUs) and require no radiation mitigation techniques. The RTAX-S devices have already been designed into several mission-critical military and aerospace systems. For example, Maxwell Technologies has applied the RTAX2000S devices to its SCS750 Super Computer for Space. "Reliability is the number one requirement for devices used at the heart of mission-critical applications. Due to the rising cost of developing RH- ASICs, the need for dependable FPGAs in the space-flight market is growing exponentially," said Ravi Pragasam, senior manager, military and aerospace product marketing at Actel. "Offering SEU immunity, usable error-corrected onboard RAM, proven reliability at extreme temperatures and live at power-up functionality on a single chip, RTAX-S devices give designers the ability to reduce component count, minimize power consumption and save board space and weight while meeting the density and performance requirements of space systems." According to Larry Longden, senior director, marketing and technology, Maxwell Technologies, "For space systems, we apply our proprietary component shielding technology and novel system-level architecture to ensure our systems are reliable and able to withstand the effects of solar flares and other environmental radiation. The SEU-immune Actel RTAX-S devices provide unparalleled reliability in extreme conditions as well as the robust feature set and density we need to accomplish our aggressive design goals. Further, Actel's long-standing reputation for delivering high-quality solutions for space applications made selecting the RTAX-S devices an easy decision." Proven SEU Immunity Provides Peace of Mind The RTAX-S family incorporates SEU-hardened flip flops, providing a cost-sensitive design solution by eliminating the need to implement triple-module redundancy (TMR). The devices offer inherent single-event latch-up (SEL) immunity greater than 104MeV-cm2/mg; immunity to SEUs with an LET threshold far greater than 37MeV-cm2/mg; and total ionizing dose (TID) performance of up to 200 Krads parametric. The family also features embedded RAM with an upset rate of <1e-10 errors> its Web site. Further, in response to industry needs for reliability data beyond the standard MIL-STD 883B process flow, Actel has established an additional Enhanced Antifuse Qualification (EAQ) step that includes lifetime testing at varying high-temperature and low-temperature conditions using a complex design to provide test data that validates the robust nature of programmed RTAX-S devices. NSREC Reception to Highlight Qualification Actel will highlight the RTAX-S qualification during its reception at the 2005 Nuclear and Space Radiation Effects Conference (NSREC) on July 14, 2005 in Seattle, Wash. The reception will also include a keynote address by Actel CEO and president John East. To register for this event, please visit http://www.actel.com/nsrec2005 . Pricing and Availability The three RTAX-S devices are currently available in volume, with prices starting at $3,580 each in quantities of 100 for the RTAX250S B flow.
