The IA82050 is a "plug-and-play" drop-in replacement for the original IC. 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 documents all necessary engineering information about the IA82050 including functional
and I/O descriptions, electrical characteristics and applicable timing.
