Actel's radiation-tolerant RTAX-DSP FPGAs have completed qualification in accordance with the military and aerospace industry standard MIL-STD-883 Class B specification.
This qualification expands Actel's support of high-speed signal processing applications for space payloads and exemplifies its ongoing innovation and commitment to serve designers of spaceflight systems.
RTAX-DSP FPGAs offer designers the same reliability characteristics as the widely-adopted RTAX-S FPGAs, and also include enhancements to improve tolerance to radiation-induced single-event transients.
When compared to radiation-hardened ASICs and SRAM-based FPGAs, RTAX-DSP FPGAs give designers a compelling alternative for signal processing applications in space, with flight-proven and trusted programming technology immune to radiation effects in space, and no non-recurring engineering charges.
RTAX-DSP FPGAs offer up to 15 billion multiply-accumulates per second at densities of up to 4 million equivalent system gates and 840 user I/Os for space-based applications, and include embedded radiation-tolerant multiply-accumulate blocks (mathblocks) to the tried-and-trusted industry-standard RTAX-S architecture. The result is a increase in device performance and utilization when implementing arithmetic functions, such as those encountered in DSP algorithms.
New radiation single-event effect hardening techniques have been implemented in the DSP Mathblocks and in the logic fabric. Radiation testing has demonstrated the effectiveness of these techniques in mitigating radiation single event transients with little area overhead and time penalty.
RTAX-DSP FPGAs are available in two sizes, RTAX4000D and RTAX2000D. RTAX2000D and RTAX4000D are available in 352-pin CQFP and 1272-pin CCGA packages, with processing flows up to a flow equivalent to QML class V. Both devices are pin compatible with certain RTAX-S counterparts and will support the same IP.
Actel's RT flash-based ProASIC3family has also successfully passed the extensive testing required for MIL-STD-883 Class B qualification.
The RT ProASIC3 FPGA family provides designers of spaceflight systems with reprogrammability for prototyping and design validation, while at the same time offering critical immunity to radiation induced configuration upsets.
The devices are based on the proven ProASIC3 flash architecture and are offered in two sizes. The 600,000 gate RT3PE600L and the three million gate RT3PE3000L are both offered in ceramic column grid array, ceramic land grid array, and ceramic quad flat-pack packages. RT ProASIC3 FPGAs can operate at a core voltage variable between 1.2 V for low power applications and 1.5 V for performance-driven designs.
