DESCRIPTION:
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.
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.
