SEE spaceflight measurements are presented on HM65756 SRAM from Matra-
MHS, Seeq 28C256 and Motorola MC68020 microprocessor (bulk version) in
the MIR station orbit (350 km altitude, 51.6 degrees inclination). Ac
celerator testing (heavy ion and proton) of flight spares permits the
prediction of the event rates using standard model such as CREME and S
PACERAD(1) as well as characterisations of the flight components allow
ing the comparison of in-orbit observations. Event rate prediction and
ground-testing data are compared.
