The IA82050 is a "plug-and-play" drop-in replacement for the original IC. Innovasic produces

replacement ICs using its MILES

technology. This technology produces replacement ICs far more complex than "emulation"

while ensuring they are compatible with the original IC. MILES

clone so it can be produced even as silicon technology advances. MILES

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.
