• Single Event Effects:
fully conforms to the ANSI/IEEE floating-point standard.
- SEU Threshold is ~ 3.38 MeV/mg/cm2
Using a numerics oriented architecture, the 80387DX adds

age. It eliminates the need for box shielding while providing
the required radiation shielding for a lifetime in orbit or space
mission. In a GEO orbit, RAD-PAK provides greater than 100
krad (Si) radiation dose tolerance. This product is available
with screening up to Class S.
