NS486
SXL
Optimized 32-Bit 486-Class Controller with On-Chip
Peripherals for Embedded Systems
General Description
The NS486SXL is a highly integrated embedded system
controller incorporating an Intel486
-class 32-bit processor
along with all of the necessary System Service Elements,
implementing a true “system on a chip.” It is ideally suited for
a wide variety of applications running in a segmented
protect-mode environment. The NS486SXL is the second
member of the NS486 family.
