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.
