® Rad Hard Products for Satellites and Space

® QPRO for Avionics  Standard QPRO products immune to upsets in avionics environment  Extensive neutron SEU testing performed - Stability of device storage cells prevents upsets - Readback feature allows user to verify data in the configuration latches  No reported instance of alpha particle induced soft error - Polyimide coating provides effective barrier

® Neutron Testing Results Single-Event Upset  Devices Tested XC4010E (5V) 178,096 SRAM-bits XC4010XL (3.3V)283,376 SRAM-bits  Irradiated with 100MeV cyclotron neutron energy  SEU Rate at aircraft altitude (~30,000 Ft.) XC4010E: 1 bit error per 600,000 flight hours (68.5 years) XC4010XL: 1 bit error per 125,000 flight hours (14.3 years)  No Latch-up

® Major Avionics Customer Conclusion “SRAM-based FPGAs (Xilinx XC4000 series) show a low susceptibility to single event upsets caused by high energy neutrons…… we conclude that these SRAM-based FPGAs can be used without limitation in the atmospheric radiation environment, contrary to large SRAM memories where precaution in the use is necessary because of neutron-induced SEU.“
