Actel is offering a range of prototype devices for demonstrating and validating designs targeted to its RTAX-DSP space-flight FPGAs.

The RTAX-DSP prototype devices have the same pin assignment, mechanical footprint and identical timing properties across the full military temperature range (-55°C to 125°C) as their space-qualified counterparts.

“The availability of RTAX-DSP prototype FPGAs enable designers to demonstrate their RTAX-DSP designs in hardware across the full operational temperature range,” said Ken O'Neill, director of high-reliability marketing for Actel.

RTAX-DSP FPGAs feature up to 120 multiply-accumulate DSP mathblocks, protected against radiation-induced single event upsets (SEU) and single event transients (SET).

The RTAX-DSP FPGAs use the same 0.15µm UMC wafer fabrication process and the same antifuse programmable interconnect technology that are used in the industry-standard RTAX-S FPGA family, which is now accumulating space-flight heritage on as many as nine space programs.

RTAX-DSP FPGAs offer high performance at densities of up to four million equivalent system gates and 840 user I/Os for space-based applications.

The embedded DSP mathblocks feature 18 bit x 18 bit multiply-accumulate blocks enabling efficient implementation of DSP building blocks, such as finite impulse response (FIR) filters, infinite impulse response (IIR) filters, and fast Fourier transforms (FFT). Each mathblock is capable of operating at 125 MHz across the full military temperature range.
