Actel has announced that its radiation-tolerant RTSX-S family of field-programmable gate arrays (FPGAs) is now available from UMC's wafer foundry. The new family (RTSX-SU) provides customers with an alternate source for its 0,25 μm devices, which have been widely adopted for radiation-intensive space-flight applications.
"UMC is the high-volume fab producing our SX-A and eX commercial FPGAs. We have worked closely with them to maintain tight control of process parameters to ensure that our customers receive the highest levels of reliability," said Ken O'Neill, director, military and aerospace product marketing at Actel. "Our tests on the UMC SX-A, eX, and now RTSX-SU silicon have demonstrated that the UMC antifuse devices are extremely reliable."
Actel's RTSX-SU family is built on a foundation of hardened latches, which eliminates 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 device's programmable logic.
The antifuse-based RTSX-SU family includes the 32 000 gate RTSX32SU and the 72 000 gate RTSX72SU (16 000 and 36 000 ASIC gates respectively) and offers system performance in excess of 250 MHz. Software to support the UMC RTSX-SU FPGAs is also available.
