Freescale Semiconductor

Power Dissipation

Table 5 provides power dissipation information. The modes are 1:1, where CPU and bus speeds are equal,

and 2:1, where CPU frequency is twice the bus speed.

NOTE

Values in Table 5 represent VDDL-based power dissipation and do not

include I/O power dissipation over VDDH. I/O power dissipation varies

widely by application due to buffer current, depending on external circuitry.

DC Characteristics

Table 6 provides the DC electrical characteristics for the MPC860.
