Notes:
1. These values apply for all valid processor bus and L2 bus ratios. The values do not include I/O supply
power (OV_DD and L2OV_DD) or PLL/DLL supply power (AV_DD and L2AV_DD). OV_DD and L2OV_DD power is
system dependent, but is typically <5% of V_DD power. Worst case power consumption for AV_DD = 15
mW and L2AV_DD = 15 mW.
2. Maximum power is measured at 105°C, at V_DD = 1.8V or 1.5Vwhile running an entirely cache-resident,
contrived sequence of instructions which keep the execution units, including AltiVec, maximally busy.
3. Typical power is an average value measured at 65°C, V_DD = 1.8V or 1.5V,
OV_DD = L2OV_DD = 2.5V in a system while running a codec application that is AltiVec intensive.
4. These values include the use of AltiVec. Without AltiVec operation, estimate a 25% decrease.
5. Power consumption derating at low temperatures to be defined after device characterization.
