6 / 12 page MPC7448 Hardware Specifications Addendum for the MC7448xxnnnnNx Series, Rev. 6 6 Freescale Semiconductor General Parameters Table 7. Power Consumption for MPC7448 at Maximum Rated Frequency Die Junction (Tj) (•C) C) Maximum Processor Core Frequency (Speed Grade, MHz) Unit Notes 600, 667 800, 867 1000 1250 1267 7 1400 Full-Power Mode Typical, Nominal 65 8.5 9.0 9.5 10.0 8.4 11.0 W 1, 2 Typical, Thermal 105 10.8 11.4 12.0 12.6 10.3 13.7 W 1, 5 Maximum 105 12.5 13.2 13.9 14.6 12.0 15.9 W 1, 3 Nap Mode Typical 105 6.5 6.5 6.5 8.3 6.5 8.3 W 1, 6 Sleep Mode Typical 105 6.3 6.3 6.3 8.0 6.3 8.0 W 1, 6 Deep Sleep Mode (PLL Disabled) Typical 105 6.0 6.0 6.0 7.7 6.0 7.7 W 1, 6 Notes: 1. These values specify the power consumption for the core power supply (VDD) at nominal voltage and apply to all valid processor bus frequencies and configurations. The values do not include I/O supply power (OVDD) or PLL supply power (AVDD). OVDD power is system dependent but is typically < 5% of VDD power. Worst case power consumption for AVDD <13mW. 2. Typical nominal power consumption is an average value measured at the nominal recommended VDD (see Table 4) and 65 °C while running the Dhrystone 2.1 benchmark and achieving 2.3 Dhrystone MIPs/MHz. This parameter is not 100% tested but periodically sampled. 3. Maximum power consumption is the average measured at nominal VDD and maximum operating junction temperature (see Table 4) while running an entirely cache-resident, contrived sequence of instructions to keep all the execution units maximally busy. 4. 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. 5. Typical thermal power consumption is an average value measured at the nominal recommended VDD (see Table 4) and 105 °C while running the Dhrystone 2.1 benchmark and achieving 2.3 Dhrystone MIPs/MHz. This parameter is not 100% tested but periodically sampled. 6. Typical power consumption for these modes is measured at the nominal recommended VDD (see Table 4) and 105°C in the mode described. This parameter is not 100% tested but is periodically sampled. 7. Power consumption for the 1267 MHz device is intentionally constrained via testing and sorting to assure low power consumption for this device. |
