Abstract :
This paper presents the SEU & MCU detected by several dedicated memories of the instrument ICARE onboard the Argentinean satellite SAC-C from November 2000 to May 2009. The correlation between SEU rate and the space environment is shown along with the evolution of the geomagnetic cut-off, the geographical dependence of the MBU multiplicity inside the SAA is also shown. Moreover, the output of MUSCA SEP3 (SEE prediction code) has been compared with in-flight data obtaining a good match.
