Actel Corporation today announced the availability of the first member of its radiation-tolerant RTSX-S family, the RT54SX32S.

The RTSX-S family ranges in density from 32,000 to 72,000 typical gates, and offers system performance in excess of 250 MHz. The Actel RTSX-S family is built on a foundation of hardened latches, which obviate the need for triple module redundancy (TMR).

Traditional FPGAs, which do not use hardened latches, force the user to implement TMR using software or a large portion of the FPGA's programmable logic. This inefficient process of majority voting, or redundancy, means that two-thirds of the density, or available logic, is consumed for redundancy and isn't available for the user's design. By including hardened latches, designers can use all available density in RTSX-S devices.
