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.
