Notes:
1. These values apply for all valid processor 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
= 15 mw and L2AVdd = 15 mW.
2. Maximum power is measured at Vdd = 2.1V while running an entirely cache-resident, contrived
sequence of instructions which keep the execution units maximally busy.
3. Typical power is an average value measured at Vdd = AVdd = L2AVdd = 2.0V, OVdd = L2OVdd =
3.3V in a system executing typical applications and benchmark sequences.
