Question: What is the difference between CY7C64603 and CY7C64613?
Answer: The only difference between the two is that the CY7C64613 supports Isochronous transfers. You can substitute the CY7C64603 for the CY7C64613 if you are not using Isochronous transfers. Likewise, you can substitute the CY7C64613 for the CY7C64603 at any time. Both CY7C64603 and CY7C64613 are obsolete and the functional ( not pin-pin) replacement is CY7C64713.
