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 = 1.9 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 = 1.9 V with dynamic power management enabled while running entirely
cache-resident, looping, integer instructions.
4. Power saving mode maximums are measured at VDD = 1.9 V while the device is in doze, nap, or sleep mode.
5. Typical power is measured at VDD = AVDD = 1.8 V, GVDD_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. Power consumption of PLL supply pins (AVDD and AVDD2) < 15 mW, guaranteed by design, but not tested.
8. The typical maximum GVDD_OVDD value resulted from the MPC8241 operating at the fastest frequency combination of
66:133:266 (PCI:Mem:CPU) MHz and performing continuous flushes of cache lines with alternating ones and zeros to PCI
memory and on 64-bit boundaries to local memory.
