Radiation tolerant RTAX-S/SL FPGAs from Microsemi are QML qualified

Microsemi Corporation has announced that its radiation-tolerant RTAX-S/SL field programmable gate arrays (FPGAs) have been qualified by the U.S. Defense Logistics Agency (DLA) as Qualified Manufacturers List (QML) Class V in accordance with military performance standard MIL-PRF-38535 space-level qualification requirements. QML Class V is the highest standard in the industry for space integrated circuits.

"Microsemi has been providing high-reliability solutions to the aerospace market for more than five decades, and we delivered our first radiation-tolerant RTAX-S FPGA in 2004," said Esam Elashmawi, vice president and general manager at Microsemi. "Earning QML Class V qualification with our RTAX-S/SL FPGAs solutions marks yet another important milestone in our history of innovation and this achievement is indicative of our ongoing commitment to quality."

The QML Class V qualification of the RTAX-S/SL FPGA product family provides customers with an added level of assurance that Microsemi FPGAs are of good quality and reliability. Microsemi's QML Class V parts include a 2,000 hours life test on each wafer lot and a destructive physical analysis (DPA) on each assembly lot. This removes the need for customers to perform these tests, providing scheduling and cost benefits.

Microsemi's RTAX-S/SL radiation-tolerant FPGAs are specifically designed for space applications using highly reliable and nonvolatile antifuse technology. They are offered in densities of up to 4 million equivalent system gates and 840 user I/Os, providing designers with a flexible programmable platform and the ability to efficiently accommodate last-minute design changes.

The RTAX-S/SL family has hot-swap and cold-sparing capabilities, which enable a device to be turned off to minimize power consumption during long space missions and activated only when functionality is required.

Features include:
1. Up to 540 kbits of embedded memory with optional EDAC protection
2. Total dose: 300 kRads (functional) and 200 kRads (parametric)
3. Single event upset (SEU) immunity
4. Multiple packing options (CQFP and CCGA/LGA)
5. Screening: E-Flow (Microsemi Extended Flow), B-Flow (Mil-STD-883B), and V-Flow (MIL-PRF-38535 QML Class V)
