The IA8044/IA8344 is a "plug-and-play" drop-in replacement for the original IC. InnovASIC  
produces replacement ICs using its 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 IA8044/IA8344 including functional and I/O  
descriptions, electrical characteristics, and applicable timing.
