The CRRES satellite's highly elliptical orbit exposes the SEU-sensitive devices within the microelectronics package to both the trapped protons of the inner radiation belts and the cosmic rays of deep space. Preliminary data from sensitive devices show more upsets due to protons than due to cosmic rays on this type orbit. This is consistent with pulse-height spectra measured from a photodiode within the package. Preliminary data obtained with the ratemeter experiment in the inner radiation belts are in reasonable agreement with predictions based on the trapped proton spectra given by the NASA AP8 model for solar maximum combined with CUPID simulations of the spallation reactions near the sensitive volumes of the memory elements. The more limited data from deep space are in agreement with the CREME calculations for cosmic ray traversals. CUPID is also in relatively good agreement with the pulse-height spectra measured in the inner belts as part of the PHA experiment
