DESCRIPTION:  
• 32-Bit microprocessor  
• RAD-PAK radiation-hardened against natural space radia-  
tion  
Maxwell Technologies’ 80386DX high performance 32-bit  
microprocessor features a geater than 100 krad (Si) total dose  
tolerance, dependent upon space mission. It is designed for  
very high performance and multitasking operating systems.  
The integrated memory management and protection architec-  
ture includes address translation registers, multitasking hard-  
ware and a protection mechanism to support operating  
systems. The 80386DX allows simultaneous running of multi-  
ple operations. In addition, the 80386DX is capable of execu-  
tion at sustained rates of between 3 and 4 million instructions  
per second. It offers new testability and debugging features,  
including a self-test and direct access to the page translation  
cache.

Total dose hardness:  
- >100 Krad (Si), dependent upon space mission  
• Single event effect:  
- SEL = 37-60 MeV/mg/cm2  
TH  
- SEUTH = 3.4 MeV/mg/cm2  
- SEU Cross section 1E-3 cm2/bit  
• Package:  
®
- 164 Pin RAD-PAK quad flat pack  
• 8, 16, 32-Bit data types  
• 8 general purpose 32-Bit registers  
Hardware debugging support  
Very large address space:  
- 4 gigabyte physical  
®
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.  
- 64 terabyte Virtual  
- 4 gigabyte maximum segment size  
Integrated memory management unit  
- Virtual memory support  
- Four levels of protection  
- Fully compatible with 80C286  
• Optimized for system development  
- Pipelined instructions  
- On-chip caches support address translation  
- 32 megabytes/sec bus bandwidth
