This section provides the AC electrical characteristics for the MPC7447A. After fabrication, functional
parts are sorted by maximum processor core frequency as shown in

considered a practical maximum in a typical single-processor system. The actual maximum SYSCLK
frequency for any application of the MPC7447A will be a function of the AC timings of the MPC7447A,
the AC timings for the system controller, bus loading, printed-circuit board topology, trace lengths, and so
forth, and may be less than the value given in
