8-Bit/16-Bit Microcontrollers
Data Sheet
July 10, 2011
1. Introduction
The Innovasic Semiconductor IA186EB and IA188EB microcontrollers are form, fit, and
function replacements for the original Intel® 80C186EB, 80C188EB, 80L186EB, and 80L188EB
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 complete 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 IA186EB and IA188EB microcontrollers replace the obsolete Intel 80C186EB and
80C188EB 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 IA186EB and IA188EB microcontrollers are an upgrade for the
80C186EB/80C188EB microcontroller designs with integrated peripherals to provide increased
functionality and reduce system costs. The IA186EB and IA188EB devices are designed to
satisfy requirements of embedded products designed for telecommunications, office automation
and storage, and industrial controls.
The IA186EB and IA188EB 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, a DRAM refresh control unit, a power management unit, and three 16-bit
timer/counters.
The IA186EB and IA188EB microcontrollers are capable of operating at 5.0 or 3.3 volts. This
datasheet discusses both modes of operation. Where applicable, characteristics specific to either
3.3 or 5.0 volt operation are identified separately throughout this datasheet.
Additionally, the IA186EB and IA188EB include two integrated serial ports that support both
synchronous and asynchronous communications, simplifying inter-processor and display
communications. The IA186EB and IA188EB also have an enhanced chip-select unit and two
multiplexed I/O ports. The enhanced chip-select unit offers 10 general chip selects, each with
the ability to address up to 1 Mbyte. This enhanced unit enables memory-bank switching to
expand the IA186EB/IA188EB 1 Mbyte address space. The I/O ports allow for basic functions
such as scanning keypads for input. The ports can also be used to control system power
consumption, disabling unneeded components.
The serial ports, I/O capabilities, and enhanced chip selects make the IA186EB/IA188EB an
excellent processor for portable data acquisition or communication applications.
