FEATURES:  
DESCRIPTION:  
Space Electronics’ 80387RP (RP for RAD-PAK®) high speed microcircuit  
features a typical 100 kilorad (Si) total dose tolerance. Using Space Elec-  
tronics radiation-hardened RAD-PAK® packaging technology, the  
80387RP 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 80387RP adds  
over seventy mnemonics to the 80386DXRP instruction set, making the  
80386DXRP/80387RP a complete solution for high-performance numer-  
ics processing. Capable of surviving space environments, the 80387RP is  
ideal for satellite, spacecraft, and space probe missions. The 80387RP has  
a total dose survivability of greater than 100 krad(Si), based on a GEO  
type orbit (actual TID tolerance depends upon orbit and mission dura-  
tion.) Space Electronics’ RAD-PAK® incorporates radiation shielding in the  
microcircuit package. It eliminates box shielding while providing lifetime  
in orbit. This product is available in Class B and Class S packaging and  
screening.
