Space-qualified FPGAs with unique hardened latches

15 August 2001 Programmable Logic

Actel has announced qualification and shipment of the RT54SX32S field-programmable gate array (FPGA), the first member of the company's radiation-tolerant RTSX-S family specifically architected to address single-event upsets (SEUs) in space. According to Actel, the RTSX-S family is the industry's first FPGA solution built using SEU-hardened latches, eliminating the need for software-based triple module redundancy (TMR).

At >63 MeV-cm2/mg SEU performance, Actel says the 32 000-gate RT54SX32S antifuse device greatly exceeds the linear energy transfer (LET) threshold of >37 MeV-cm2/mg, a physical requirement common to the majority of satellite applications. The SEU-hardened latches, total ionising dose (TID) performance in excess of 100 Krad, and inherent single-event latchup (SEL) demonstrate the RTSX-S family's robust survivability within radiation-intensive applications.

The RTSX-S family ranges in density from 32 000 to 72 000 typical gates, and offers system performance in excess of 250 MHz.

Fully-qualified RT54SX32S, MIL-STD 883 Class B and Class S-equivalent 'E flow' production quantities are available now. Software support is provided by Actel's Libero integrated design environment.
