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^(R)  packaging technol-ogy incorporates radiation shielding in the microcircuit pack-age. 80386DX 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. 80386DX is available with screening up to Class S.
