Note:
1. These values apply for all valid 60x bus and L2 bus ratios. The values do not include I/O Supply Power (OV
and L2OV
) or PLL/DLL supply power
(AV
and L2AV
DD
). OV
and L2OV
DD
power is system dependent, but is typically <10% of V
DD
power. Worst case power consumption for AV
DD
=
15mW and L2AV
= 15mW.
2. Maximum power is shown for a system executing worst case benchmark sequences at:
V
DD
= AV
= L2V
= 2.1V;
OV
= L2OV
DD
= 3.3V;
T
= 65
°
C
Maximum power at 85
°
C can be derived by adding 0.1 W to the maximum power shown at 65
°
C. Maximum power at 105
°
C can be derived by add-
ing 0.3 W to the maximum power shown at 65
°
C.
3. Typical power is an average value shown for a system executing typical applications and benchmark sequences at:
V
DD
= AV
DD
= L2AV
DD
= 2.0V (300 through 400 MHz);
V
DD
= AV
= L2AV
= 2.05V (433 through 500 MHz);
OV
= L2OV
DD
= 3.3V;
T
= 45
°
C.
4. Guaranteed by design and characterization, and is not tested.
