Power Characteristics
Table 3 provides power consumption data for the PC8245.

DD
2 = 1.8V
2. Maximum – FP power is measured at V
DD
= 2.1V with dynamic power management enabled while running an entirely cache-
resident, looping, floating-point multiplication instruction.
3. Maximum – INT power is measured at V
DD
= 2.1V with dynamic power management enabled while running entirely cache-
resident, looping, integer instructions.
4. Power saving mode maximums are measured at V
DD
= 2.1V while the device is in doze, nap, or sleep mode.
5. Typical power is measured at V
DD
= AV
DD
= 2.0V, OV
DD
= 3.3V 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 were results of the PC8245 performing cache resident integer operations at the slow-
est frequency combination of 33:66:200 (PCI:Mem:CPU) MHz
8. The typical maximum OV
DD
value resulted from the PC8245 operating at the fastest frequency combination of 66:100:350
(PCI:Mem:CPU) MHz and performing continuous flushes of cache lines with alternating ones and zeros to PCI memory.
9. The typical maximum GV
DD
value resulted from the PC8245 operating at the fastest frequency combination of 66:100:350
(PCI:Mem:CPU) MHz and performing continuous flushes of cache lines with alternating ones and zeros on 64-bit bound-
aries to local memory.
10. Power consumption of PLL supply pins (AV
DD
and AV
DD
2) < 15 mW. Guaranteed by design and is not tested.
