I'm having difficulty locating an IBIS model for the Freescale MCP553/554 or MCP5566 Power PC parts (416-pin BGA). Can anyone point me to a source? I haven't even been able to determine if they are all the same fab process. My last encounter with Freescale support was dismal. They asked if a boundary scan model would work. Thanks, Gary D.
