The IA186EM/188EM is a form, fit and function replacement for the original Advanced Micro Devices#
Am186EM/188EM 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 data 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.
