General Description\nThe NSC800 is an 8-bit CMOS microprocessor that functions as the central processing unit (CPU) in National Semiconductor's NSC800 microcomputer family. National's microCMOS technology used to fabricate this device provides system designers with performance equivalent to comparable NMOS products, but with the low power advantage of CMOS. Some of the many system functions incorporated on the device, are vectored priority interrupts, refresh control, power-save feature and interrupt acknowledge. The NSC800 is available in dual-in-line and surface mounted chip carrier packages.
