Notes:

1. These values specify the power consumption at nominal voltage and apply to all valid processor bus frequencies and

configurations. The values do not include power dissipation for I/O supplies.

2. Typical power is an average value measured at the nominal recommended core voltage (VDD_Coren) and 65°C junction

temperature (see Table 2)while running the Dhrystone 2.1 benchmark and achieving 2.3 Dhrystone MIPs/MHz.

3. Thermal power is the average power measured at nominal core voltage (VDD_Coren) and maximum operating junction

temperature (see Table 2) while running the Dhrystone 2.1 benchmark and achieving 2.3 Dhrystone MIPs/MHz and a typical

workload on platform interfaces.

4. Maximum power is the maximum power measured at nominal core voltage (VDD_Coren) and maximum operating junction

temperature (see Table 2) while running a test which includes an entirely L1-cache-resident, contrived sequence of

instructions which keep all the execution units maximally busy.

5. These power numbers are for Part Number MC8641xx1000NX only. VDD_Coren = 0.95 V and VDD_PLAT = 1.05 V.
