DESCRIPTION:

• 80-Bit numeric processor

• R^AD-PAK® radiation hardened against natural space radia-

tion

Maxwell's 80387DX high speed microcircuit features a greater

than 100 kilorad (Si) total dose tolerance. Using Maxwell's

radiation hardened R^AD-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, mak-

ing the 80386DX/80387DX a complete solution for high-per-

formance numerics processing.

• 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 addres-

sable general registers or as a register stack

• Data types include:

Maxwell Technologies' patented R^AD-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, R^AD-PAK provides greater than 100

krad (Si) radiation dose tolerance. This product is available

with screening up to Class S.

- 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 micro-

processors

• Full-range transcendental operations for SINE, COSINE,

TANGENT, ARCTANGENT and LOGARITHM
