The IA186EM/188EM is a form, fit, and function replacement for the original Advanced Micro
DevicesÒ Am186EM/188EM 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.
This Advance Information Sheet contains preliminary information for the IA186EM/188EM. The
complete data sheet which documents all necessary engineering information about the
IA186EM/188EM including functional and I/O descriptions, electrical characteristics, and
applicable timing will be available when the device nears completion.
