The IA63484 is a "plug-and-play" drop-in replacement for the original Hitachi© HD63484. This

replacement IC has been developed using innovASIC’s 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 data

sheet documents all necessary engineering information about the IA63484 including functional and

I/O descriptions, electrical characteristics, and applicable timing.
