NSC800

The 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.

The NSC800 system designer can choose not only from the dedicated 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 peripherals include NSC810A RAM I/O Timer, NSC858 UART, and NSC831 I/O.

All devices NSC800 are available in commercial, industrial and military 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.
