Low-Power CMOS Microprocessor
General Description
The NSC800isan 8-bit CMOS microprocessor that func-
tionsasthe central processingunit (CPU)in National Semi-
conductor’s NSC800 microcomputer family. National’s
microCMOS technology usedto fabricatethis device pro-
vides system designers with performance equivalentto
comparable NMOS products,but withthelow power advan-
tageof CMOS. Someof themany system functions incorpo-
ratedonthe device,are vectored priority interrupts, refresh
control, power-save featureand interrupt acknowledge.The
NSC800is availablein dual-in-line and surface mounted
chip carrier packages.
The system designercan choosenot only fromthe dedicat- CMOS peripherals that allow direct interfacingtothe
NSC800but fromthefulllineof National’s CMOS products allowa low-power system solution.Thededicated periph-
erals include NSC810A RAM I/O Timer, NSC858 UART,
and NSC831 I/O.
All devicesare availablein commercial, industrialand mili-
tary temperature ranges along with two added reliability
flows.Thefirstisan extended burnintestandthe secondis
the military classC screeningin accordance with Method
5004of MIL-STD-883.
Features Fully compatible with Z80É instructionset:
