The effect of high energy proton irradiation and angle of incidence on single-event latchup (SEL) hardness is investigated as a function of temperature and power supply voltage to determine worst-case hardness assurance test conditions for space environments. SRAMs from several vendors were characterized for single-event latchup SEL hardness at proton energies from 20 to 500 MeV at temperatures of 25 degC and 80 degC, and at both normal and grazing angles of incidence. For all SRAMs… CONTINUE READING
