Actel Corporation (Nasdaq: ACTL) developed the first radiation-tolerant, flash-based FPGAs for space-flight applications. The reprogrammability of the new low-power RT ProASIC(R)3 devices simplifies prototyping and eases hardware timing validation while offering critical immunity to radiation-induced configuration upsets. Rigorous testing of the RT ProASIC3 devices toward Mil-Std 883 Class B qualification is underway, with completion expected in early 2009.
Based on Actel’s ProASIC(R)3 architecture, the new radiation-tolerant, flash-based 600,000-gate RT3PE600L and three million-gate RT3PE3000L support power supplies ranging from 1.2 to 1.5V, which allows designers to choose the optimum balance between power consumption and performance. Because high power consumption requires larger, heavier power supply components, minimizing power consumption in space-flight systems is critical. Managing heat dissipation also requires bulky and heavy mechanical infrastructure in the spacecraft. As a result, designers are motivated to carefully monitor these factors as increased size and weight contribute to higher launch costs.
The RT3PE600L will be offered in 484-pin ceramic column grid array (CCGA) and land grid array (LGA) packages, while RT3PE3000L will be offered in both 484- and 896-pin CCGA and LGA packages.
