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^TMcaptures the design of a clone so it

can be produced even as silicon technology advances. MILES^TMalso 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.
