NS486^TMSXF Optimized 32-Bit 486-Class Controller

with On-Chip Peripherals for Embedded Systems

Intel 82365 compatible PCMCIA interface

Protected WATCHDOG^TMtimer

General Description

The NS486SXF is a highly integrated embedded system

controller incorporating an Intel486^TM-class 32-bit proces-

sor, all of the necessary System Service Elements, and a

set of peripheral I/O controllers tailored for embedded con-

trol systems. It is ideally suited for a wide variety of applica-

tions running in a segmented protect-mode environment.

Optimized DRAM Controller (supports two banks, up to

8 Mbytes each)

Up to nine versatile, programmable chip selects

Glueless interface to ISA peripherals

Arbitration support for auxiliary processor

Four external DMA channels (max. transfer rate of 25

MByte/sec

25 MHz) support many transfer modes

Key Features

High performance IEEE 1284 (ECP) Bidirectional

Parallel Port

MICROWIRE^TM/Access.bus synchronous serial

interfaces

100% compatible with VxWorks , VRTX , QNX Neu-

trino, pSOS ^TM, and other popular real-time executives

and operating system kernels

Intel486 instruction set compatible (protected mode

only) with optimized performance

LCD Controller for an up to 4 grey scale supertwist

Liquid Crystal Displays up to 480 X 320

Reconfigurable I/O: Up to 29 I/O pins can be used as

general purpose bidirectional I/O lines

Flexible, programmable, multilevel power saving modes

maximize power savings

CPU includes a 1 Kbyte Instruction Cache

Operation at 25 MHz with 5V supply

Low cost 160-pin PQFP package

Industry standard interrupt controller, timers, real time

clock, UART with IrDA v1.0 (Infrared Data Association)

port
