The IA21140AF is a "plug-and-play" drop-in replacement for the original IC. innovASIC produces
TM
replacement ICs using its MILES , or Managed IC Lifetime Extension System, cloning technology. This
technology produces replacement ICs far more complex than "emulation" while ensuring they are compatible
TM
with the original IC. MILES captures the design of a clone so it can be produced even as silicon
TM
technology advances. MILES 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 IA21140AF including functional and I/O descriptions, electrical characteristics, and applicable
timing.
