In-orbit SEU data from three microsatellites are separated into Galactic Cosmic Ray (GCR), South Atlantic Anomaly (SAA) and solar flare upsets. Heavy ion and proton testing of the same devices are reported and predictions using LET-dependent ion cross sections and a 2-parameter fit to proton cross section data are compared with in-flight data. SEU trends in memory devices from a single manufacturer, from 16 K-bit to 4 M-bit, are identified.
