Introduction
The IA186ES/IA188ES is a form, fit, and function replacement for the original Advanced Micro
Devices (AMD ) Am186ES/188ES family of microcontrollers. Innovasic produces replacement
ICs using its MILES™, or Managed IC Lifetime Extension System, cloning technology that
produces replacement ICs far more complex than “emulation” while ensuring they are
compatible with the original IC. MILES captures the design of a clone so it can be produced
even as silicon technology advances. MILES also verifies the clone against the original IC so
that even the “undocumented features” are duplicated.
1.1
General Description
The IA186ES/IA188ES family of microcontrollers replaces obsolete AMD Am186ES/188ES
devices, allowing customers to retain existing board designs, software compilers/assemblers, and
emulation tools and thus avoid expensive redesign efforts.
The IA186ES/IA188ES microcontrollers are an upgrade for the 80C186/188 microcontroller
designs, with integrated peripherals to provide increased functionality and reduce system costs.
The Innovasic devices are designed to satisfy requirements of embedded products designed for
telecommunications, office automation/storage, and industrial controls.
