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