1. Introduction

The Innovasic Semiconductor IA186XL and IA188XL microcontrollers are form, fit, and

function replacements for the original Intel 80C186XL and 80C188XL 16-bit high-integration

embedded processors.

These devices are produced using Innovasic’s Managed IC Lifetime Extension System

(MILES™). This cloning technology, which produces replacement ICs beyond simple

emulations, ensures compatibility with the original device, including any “undocumented

features.” Additionally, the MILES™ process captures the clone design in such a way that

production of the clone can continue even as silicon technology advances.

The IA186XL and IA188XL microcontrollers replace the obsolete Intel 80C186XL and

80C188XL devices, allowing users to retain existing board designs, software

compilers/assemblers, and emulation tools, thereby avoiding expensive redesign efforts.

1.1 General Description

The Innovasic Semiconductor IA186XL and IA188XL microcontrollers have a set of base

peripherals beneficial to many embedded applications and include a standard numeric interface,

an interrupt control unit, a chip-select unit/Ready Generation Logic, a DRAM refresh control

unit, a Power-Save Control unit, DMA and three 16-bit timer/counters.

The IA186XL and IA188XL microcontrollers operate at 5.0 volts ± 10%.

The following functional description describes the base architecture of the 80C186XL. The

80C186XL is a very high integration 16-bit microprocessor. It combines some of the most

common microprocessor system components onto one chip. The 80C186XL is object-code

compatible with the 8086/8088 microprocessors and adds ten new instruction types to the

8086/8088 instruction set.

The 80C186XL has two major modes of operation, Compatible and Enhanced. In Compatible

Mode, the 80C186XL is completely compatible with the 80186, with the exception of 8087

support. The Enhanced mode adds three new features to the system design. These are Power-

Save control, Dynamic RAM refresh, and an asynchronous Numerics Coprocessor interface

(80C186XL only).

1.2 Features

The primary features of the IA186XL and IA188XL microcontrollers are as follows:

Form, fit, and function compatible version of the low power Intel 80C186XL/80C188XL
