Recent single event effect (SEE) test results for the Freescale 7447A and IBM 750FX microprocessors, and Marvell 64460 bridge chips are reported. The 7447A and 750FX results are compared to earlier work. The 64460 represents unique data. The data extraction methods for each test type are described. The 7447A and 750FX were found to have a single event upset (SEU) threshold of about 1 MeV-cm2/mg and saturated cross section of 2×10-9 cm2/bit. Both devices have proton cross sections of about 10-14 cm2/bit and proton thresholds below 20 MeV. The 64460 was shown to have functional interrupts similar to single event latchup with threshold below 1 MeV-cm2/g and saturated cross section around 1 cm2.
