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
DD
= 15mW.
2. Maximum power is measured in a system executing worst case benchmark sequences at:
V
DD
= AV
= L2V
= 2.1V;
OV
= L2OV
= 3.3V;

= 105
°
C (300, 333, 366 MHz);
85

C (466 MHz).
3. Typical power is an average value measured in a system executing typical applications and benchmark sequences at:
V
DD
= AV
DD
= L2AV
DD
= 2.0V (300, 333, 366, 400 MHz);
V
DD
= AV
= L2AV
= 2.05V (466 MHz);
OV
= L2OV
DD
= 3.3V;
T

C.
4. Power dissipation is reduced approximately.1W per 10 degree C reduction in T
j
.
5. Guaranteed by design and characterization, and is not tested.
