High-Performance
Low-Power CMOS Microprocessor
General Description
The NSC800 is an 8-bit CMOS microprocessor that func-
tions as the central processing unit (CPU) in National Semi-
conductor’s
NSC800
microcomputer
microCMOS technology used to fabricate this device pro-
vides system designers with performance equivalent to
comparable NMOS products, but with the low power advan-
tage of CMOS. Some of the many system functions incorpo-
rated 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.
family.
National’s
The system designer can choose not only from the dedicat-
ed CMOS peripherals that allow direct interfacing to the
NSC800 but from the full line of National’s CMOS products
to allow a low-power system solution. The dedicated periph-
erals include NSC810A RAM I/O Timer, NSC858 UART,
and NSC831 I/O.
All devices are available in commercial, industrial and mili-
tary temperature ranges along with two added reliability
flows. The first is an extended burn in test and the second is
the military class C screening in accordance with Method
5004 of MIL-STD-883.
