Actel Corp. has announced performance improvements on its radiation-tolerant RTAX-S and RTAX-SL space-flight FPGAs, offering designers of space applications even greater advantages.

Unburdened by the cost and schedule risks associated with radiation-hardened ASICs, the RTAX-S/SL family is the ideal choice for use in space-flight applications requiring built-in protection from radiation-induced single-event upset (SEU) events, says Actel.

The enhancements to the RTAX-S/SL family of FPGAs include reduced static power consumption of up to 80 percent. This saving in static power is important for systems that go into stand-by mode and need to retain register and memory states while the spacecraft is running in battery mode.

Additional features include faster speed grade for the 4-million gate RTAX4000S FPGA, bringing 10 percent higher performance to the largest SEU-protected radiation-tolerant FPGA, a low-power RTAX4000SL FPGA, reducing static power consumption by 50 percent compared to the RTAX4000S FPGA, and new 624-pin CCGA and LGA packages for the RTAX250S/SL FPGA, giving designers a 17 percent increase in available I/Os and more than 50 percent savings in footprint.

The RTAX-S/SL FPGA also offers an increased absolute maximum junction temperature of 135C, giving designers an additional 10C buffer to run the devices faster or at higher case temperatures.
