The Intel387
TM
SX Math CoProcessor is an extension to the Intel386
TM
SX microprocessor architecture. The
combination of the Intel387
TM
SX with the Intel386
TM
SX microprocessor dramatically increases the process-
ing speed of computer application software that utilizes high performance floating-point operations. An internal
Power Management Unit enables the Intel387
TM
SX to perform these floating-point operations while maintain-
ing very low power consumption for portable and desktop applications. The internal Power Management Unit
effectively reduces power consumption by 95% when the device is idle.
The Intel387
TM
SX Math CoProcessor is available in a 68-pin PLCC package, and is manufactured on Intel’s
advanced 1.0 micron CHMOS IV technology.
