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 architecture includes address translation registers, multitasking hardware and a protection mechanism to support operating
systems. The 80386DX allows simultaneous running of multiple operations. In addition, the 80386DX is capable of execution 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.

Maxwell Technologies' patented RAD-PAK® packaging technology incorporates radiation shielding in the microcircuit package. 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.
