1.1 DC Electrical Characteristics
Table 1. Part Numbers Addressed by this Data Sheet
MPC7447A RISC Microprocessor Hardware Specifications. Table 2. Recommended Operating Conditions 1
- These are the recommended and tested operating conditions. In addition, these devices also support voltage
and those specified in Section 1.3 is not guaranteed.
- This voltage is the input to the filter discussed in MPC7447A RISC Microprocessor Hardware Specifications,
- VDD and AVDD may be reduced in order to reduce power consumption if further maximum core frequency
constraints are observed. See Section 1.3, “Voltage and Frequency Derating,” for specific information. Table 3. Power Consumption for MPC7447A

1.2 AC Electrical Characteristics
Table 4 provides the clock AC timing specifications for the MPC7447A part numbers described herein.
- These values apply for all valid processor buses. The values do not include I/O supply power (OVDD) or PLL supply
- Typical power is an average value measured at the nominal recommended VDD (see Table 2) and 65°C while
running the Dhrystone 2.1 benchmark and achieving 2.3 Dhrystone MIPs/MHz.
- Maximum power is the average measured at nominal VDD and maximum operating junction temperature (see
- Doze mode is not a user-definable state; it is an intermediate state between full-power and either nap or sleep mode.
As a result, power consumption for this mode is not tested. Table 4. Clock AC Timing Specifications At recommended operating conditions. See Table 2.
- Caution: The SYSCLK frequency and PLL_CFG[0:4] settings must be chosen such that the resulting SYSCLK
Hardware Specifications, Section 9.1, “PLL Configuration,” for valid PLL_CFG[0:4] settings.
- Caution: If dynamic frequency switching (DFS) is enabled, the SYSCLK frequency and PLL_CFG[0:4] settings must
be chosen such that the resulting processor frequency is greater than or equal to the minimum core frequency.
- Caution: These values specify the maximum processor core and VCO frequencies when the device is operated at
frequencies must be reduced. See Section 1.3, “Voltage and Frequency Derating,” for more information. Table 3. Power Consumption for MPC7447A (continued)

Ordering Information
1.2.1 Processor Bus AC Specifications
Devices described by this hardware specification addendum conform to the processor bus AC timing specifications provided in the MPC7447A RISC Microprocessor Hardware Specifications. Please refer to that document for this information.
1.3 Voltage and Frequency Derating
To reduce the power consumption of the device, these devices support voltage and frequency derating whereby the core voltage (VDD) may be reduced if the reduced maximum processor core frequency requirements are observed. The supported derated core voltage, resulting maximum processor core frequency (fcore), and power consumption are provided in Table 5. Only those parameters in Table 5 are affected; all other parameter specifications are unaffected.
