Introduction
The IA186ER/IA188ER is a form, fit, and function replacement for the original Advanced Micro
Devices Am186ER/Am188ER family of microcontrollers. Innovasic produces replacement ICs
using its MILESTM, or Managed IC Lifetime Extension System cloning technology. This
technology produces replacement ICs far more complex than “emulation” while ensuring they
are compatible with the original IC. MILESTM captures the design of a clone so it can be
produced even as silicon technology advances. MILESTM also verifies the clone against the
original IC so that even the “undocumented features” are duplicated.
1.1
General Description
The IA186ER/IA188ER family of microcontrollers replaces obsolete Am186ER/188ER devices,
allowing customers to retain existing board designs, software compilers/assemblers and
emulation tools, thereby avoiding expensive redesign efforts.
The IA186ER/IA188ER microcontrollers are an upgrade for the 80C186/80C188 microcontroller
designs, with integrated peripherals to provide increased functionality and reduce system costs.
The Innovasic devices are created to satisfy requirements of embedded products designed for
telecommunications, office automation and storage, and industrial controls.
