MPC7447A RISC Microprocessor Hardware Specifications, Rev. 5

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.”

Capacitance,

0 V, f = 1 MHz

All other inputs C

—8.0pF5

Notes:

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

2. For processor bus signals, the reference is OV

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

4. The leakage is measured for nominal OV

and V

, or both OV

and V

must vary in the same direction (for

example, both OV

and V

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.
