General Description
The NS486SXF is a highly integrated embedded system
controller incorporating an Intel486TM-class 32-bit processor,
all of the necessary System Service Elements, and a
set of peripheral I/O controllers tailored for embedded control
systems. It is ideally suited for a wide variety of applications
running in a segmented protect-mode environment.
