A80186

HIGH-INTEGRATION 16Bit MICROPROCESSOR

FUNCTIONAL DESCRIPTION

Introduction

The following Functional Description describes the base architecture of the 80186. The 80186 is a very

high integration 16-bit microprocessor. It combines 15± 20 of the most common microprocessor system

components onto one chip while providing twice the performance of the standard 8086. The 80186 is ob

ject code compatible with the 8086/8088 microprocessors and adds 10 new instruction types to the 8086/8088 instruction set.
