Power Dissipation
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 <10% 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.
