The IA82050 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 IA82050 including functional and I/O
descriptions, electrical characteristics, and applicable timing.
