MPC7447A RISC Microprocessor Hardware Specifications, Rev. 5

Freescale Semiconductor

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.”

Capacitance,

Vin = 0 V, f = 1 MHz

All other inputs

Cin

—8.0

Notes:

1. Nominal voltages; see Table 4 for recommended operating conditions.

2. For processor bus signals, the reference is OVDD

3. Excludes test signals and IEEE 1149.1 boundary scan (JTAG) signals

4. The leakage is measured for nominal OVDD and VDD, or both OVDD and VDD must vary in the same direction (for

example, both OVDD and VDD 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.
