Abstract

The purpose of this study is to characterize the single-event-effects (SEE) performance due to heavy-ion irradiation of the SN55LVRA4-SEP. SEE performance was verified at minimum (3V) and maximum (3.6V) operating conditions. Heavy-ions with an LETEFF of 50MeV-cm2/ mg (for SEL) and LETEFF of 47MeV-cm2/ mg (for SET) were used to irradiate five production devices with a fluence of 1 × 107 ions / cm2. The results demonstrate that the SN55LVRA4-SEP is SEL-free up to LETEFF = 50MeV-cm2 / mg as 125°C. SET performance at minimum and maximum operating voltages saw excursions, as shown and discussed in this report.
