SPRK066 October 2025 F28377D-SEP
The purpose of this study is to characterize the single-event effects (SEE) performance due to heavy-ion irradiation of the F28377D-SEP. Heavy-ions with LETEFF of 45MeV·cm2 /mg were used to irradiate three pre-production devices. Flux of ≅ 105ions×cm2/s and fluence of ≅107 ions/cm2for SEL and Flux of ≅ 104ions×cm2/s fluence of ≅106 ions/cm2 for SET per run were used for the characterization. The results demonstrated that the F28377D-SEP is SEL-free up to 45MeV·cm2/mg at T = 125°C in addition to effects of SET at T = 25°C. SET transients performance was monitored during checking for excursions of >|3%| from the nominal output on independent GPIO outputs that were controlled by CPU1 and CPU2 respectively while code is executing during both SEL and SET testing.
