    Comparison with the MPC7447, MPC7445, and
    MPC7441
    Table 1 compares the key features of the MPC7447A with the key features of the earlier MPC7447,
    MPC7445, and MPC7441. All are based on the MPC7450 RISC microprocessor and are very similar
    architecturally. The MPC7447A is identical to the MPC7447 but includes the DFS and temperature diode
    features.
