The IA186ES/188ES is a form, fit, and function replacement for the original Advanced Micro DevicesÒ Am186ES/188ES family of microcontrollers. innovASIC produces replacement ICs using its MILES^TM, 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. MILES^TM captures the design of a clone so it can be produced even as silicon technology advances. MILES^TM also verifies the clone against the original IC so that even the "undocumented features" are duplicated.

This Advance Information Sheet contains preliminary information for the IA186ES/188ES. The complete data sheet which documents all necessary engineering information about the IA186ES/188ES including functional and I/O descriptions, electrical characteristics, and applicable timing will be available when the device nears completion.

Description

The IA186ES/188ES family of microcontrollers replaces obsolete AMDÒ Am186ES/188ES devices, allowing customers to retain existing board designs, software compilers/assemblers, and emulation tools, thereby avoiding expensive redesign efforts.

The IA186ES/188ES 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 and storage, and industrial controls.
