Freescale Semiconductor 13
Electrical and Thermal Characteristics
Table 7 provides the power consumption for the MPC7447A. For information regarding power
consumption when dynamic frequency switching is enabled, see Section 9.8.5, “Dynamic Frequency
Switching (DFS).”
NOTE
The power consumption information in this table applies when the device is
operated at the nominal core voltage indicated in Table 4. For power
consumption at derated core voltage conditions, see Section 5.3, “Voltage
and Frequency Derating.”

Notes:
1. Nominal voltages; see Table 4 for recommended operating conditions.
2. For processor bus signals, the reference is OV
DD
3. Excludes test signals and IEEE 1149.1 boundary scan (JTAG) signals
4. The leakage is measured for nominal OV

and V
DD
, or both OV
DD
and V
DD
must vary in the same direction (for
example, both OV
DD
and V
DD
vary by either +5% or –5%).
5. Capacitance is periodically sampled rather than 100% tested.
6. Excludes signals with internal pullups: BVSEL, LSSD_MODE
, TDI, TMS, and TRST.
