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.
