80-Bit numeric processor RAD-PAK radiation hardened against natural space radiation Total dose hardness: - > 100 krad (Si) - dependant upon space mission Single Event Effects: - SEU Threshold is ~ 3.38 MeV/mg/cm2 - SEL Threshold = 37.1 - 59.9 MeV/mg/cm2 Package: 68-pin RAD-PA quad flat pack Eight 80-bit numeric registers, usable as individual addressable general registers or as a register stack Data types include: - 32-, 64-, 80-bit floating point - 32-, 64-bit integers - 18-digit BCD operands 5 V Only power Built-in exception handling Upward object code compatible with All 80X87DX microprocessors Full-range transcendental operations for SINE, COSINE, TANGENT, ARCTANGENT and LOGARITHM
DESCRIPTION:
Maxwell's 80387DX high speed microcircuit features a greater than 100 kilorad (Si) total dose tolerance. Using Maxwell's radiation hardened RAD-PAK packaging technology, the 80387DX is a high-performance numerics processor that extends the 80386DX architecture with floating point, extended integer and BCD data types. The computing system fully conforms to the ANSI/IEEE floating-point standard. Using a numerics oriented architecture, the 80387DX adds over seventy mnemonics to the 80386DX instruction set, making the 80386DX/80387DX a complete solution for high-performance numerics processing. Maxwell Technologies' patented RAD-PAK packaging technology incorporates radiation shielding in the microcircuit pack……
