Notes:
1.
The values include VDD, AVDD, and AVDD2, but do not include I/O supply power.
2.
Maximum—FP power is measured at VDD = 2.1 V with dynamic power management enabled while running an entirely
cache-resident, looping, floating 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 = 2.1 V, OVDD = 3.3 V where a nominal FP value, a nominal INT value, and a
value where there is a continuous flush 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 was the result 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 66:133:399
(PCI:Mem:CPU) MHz for the 400-MHz part, and performing continuous flushes 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
66:133:399 (PCI:Mem:CPU) MHz for the 400-MHz part, and performing continuous flushes 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 that the design guarantees but were not tested.
