The IA63484 is a "plug-and-play" drop-in replacement for the original Hitachi© HD63484. This
replacement IC has been developed using innovASIC’s 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 IA63484 including functional and
I/O descriptions, electrical characteristics, and applicable timing.
