ESCRIPTION
:
DDC's
80387DX high speed microcircuit features a greater
than 100 kilorad (Si) total dose tolerance. Using
DDC's
radiation hardened R
AD
-P
AK
® packaging technology, the
80387DX is a high-performance numerics processor that
extends the 80386DX architecture with floating point,
extended integer and BCD data types. The computing system
fully conforms to the ANSI/IEEE floating-point standard.
Using a numerics oriented architecture, the 80387DX adds
over seventy mnemonics to the 80386DX instruction set, mak-
ing the 80386DX/80387DX a complete solution for high-per-
formance numerics processing.
DDC's
patented R
AD
-P
AK
packaging technol-
ogy incorporates radiation shielding in the microcircuit pack-
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, R
AD
-P
AK
provides greater than 100
krad (Si) radiation dose tolerance. This product is available
with screening up to Class S.
