Notes:
1.
The values include VDD, AVDD, and AVDD2 but do not include I/O supply power, see Section 1.7.2, “Power Supply
Sizing,” for information on OVDD and GVDD supply power. Values shown in parenthesis ( ) indicate power
consumption at VDD/AVDD/AVDD2 = 1.8 V.
2.
Maximum—FP power is measured at VDD = 2.1 V with dynamic power management enabled while running an
entirely cache-resident, looping, oating-point multiplication instruction.
3.
Maximum—INT power is measured at VDD = 2.1 V with dynamic power management enabled while running
entirely cache-resident, looping, integer instructions.
4.
Power saving mode maximums are measured at VDD = 2.1 V while the device is in doze, nap, or sleep mode.
5.
Typical power is measured at VDD = AVDD = 2.0 V, OVDD = 3.3 V where a nominal FP value, a nominal INT value,
and a value where there is a continuous ush of cache lines with alternating ones and zeros on 64-bit boundaries
to local memory are averaged.
6.
Power saving mode data measured with only two PCI_CLKs and two SDRAM_CLKs enabled.
7.
The typical minimum I/O power values were results of the MPC8245 performing cache resident integer operations
at the slowest frequency combination of 33:66:200 (PCI:Mem:CPU) MHz.
8.
The typical maximum OVDD value resulted from the MPC8245 operating at the fastest frequency combination of
66:100:350 (PCI:Mem:CPU) MHz and performing continuous ushes of cache lines with alternating ones and
zeros to PCI memory.
9.
The typical maximum GVDD value resulted from the MPC8245 operating at the fastest frequency combination of
66:100:350 (PCI:Mem:CPU) MHz and performing continuous ushes of cache lines with alternating ones and
zeros on 64-bit boundaries to local memory.
10. Power consumption of PLL supply pins (AVDD and AVDD2) < 15 mW. Guaranteed by design and is not tested.
