The IA2910A 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 IA2910 including
functional and I/O descriptions, electrical characteristics, and applicable timing.
