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. Logic Diagram 22 144 145 21 62 63 103 104 |
