1. These values apply for all valid 60x bus and L2 bus ratios. The values do not include I/O Supply Power (OVDD and L2OVDD) or PLL/DLL supply power
(AVDD and L2AVDD). OVDD and L2OVDD power is system dependent, but is typically <10% of VDD power. Worst case power consumption for AVDD
15mW and L2AVDD = 15mW.
=
2. Maximum power is measured in a system executing worst case benchmark sequences at:
•
•
•
VDD = AVDD = L2VDD = 2.1V;
OVDD = L2OVDD = 3.3V;
Tj = 105 °C (300, 333, 366 MHz);
85°C (400 MHz);
65°C (466 MHz).
3. Typical power is an average value measured in a system executing typical applications and benchmark sequences at:
•
•
•
•
VDD = AVDD = L2AVDD = 2.0V (300, 333, 366, 400 MHz);
VDD = AVDD = L2AVDD = 2.05V (466 MHz);
OVDD = L2OVDD = 3.3V;
Tj = 45 °C.
4. Power dissipation is reduced approximately.1W per 10 degree C reduction in Tj.
5. Guaranteed by design and characterization, and is not tested.
