Overview
80386DX 32-Bit Microprocessor 21 145 22 144 62 104 63 103 Logic Diagram Memory FEATURES: • 32-Bit microprocessor • RAD-PAK® radiation-hardened against natural space radiation • Total dose hardness: - >100 Krad (Si), dependent upon space mission • Single event effect: - SELTH = 37-60 MeV/mg/cm2 - 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 - 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 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 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.
