80387DX  
Math Coprocessor  
80387  
Logic Diagram  
FEATURES:  
DESCRIPTION:  
• 80-Bit numeric processor  
• RAD-PAK® radiation hardened against natural space radia-  
tion  
Maxwell's 80387DX high speed microcircuit features a greater  
than 100 kilorad (Si) total dose tolerance. Using Maxwell's  
radiation hardened RAD-PAK® 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.  
Total dose hardness:  
- > 100 krad (Si)  
- dependant upon space mission  
• Single Event Effects:  
- SEU Threshold is ~ 3.38 MeV/mg/cm2  
- SEL Threshold = 37.1 - 59.9 MeV/mg/cm2  
• Package: 68-pin RAD-PA® quad flat pack  
• Eight 80-bit numeric registers, usable as individual addres-  
sable general registers or as a register stack  
Data types include:  
Maxwell Technologies' patented RAD-PAK 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, RAD-PAK provides greater than 100  
krad (Si) radiation dose tolerance. This product is available  
with screening up to Class S.  
- 32-, 64-, 80-bit floating point  
- 32-, 64-bit integers  
- 18-digit BCD operands  
• 5 V Only power  
Built-in exception handling  
Upward object code compatible with All 80X87DX micro-  
processors  
• Full-range transcendental operations for SINE, COSINE,  
TANGENT, ARCTANGENT and LOGARITHM
