Power Characteristics
The power dissipation for the dual core PC8641D device is shown in Table 4-1.
Notes:
1. These values specify the power consumption at nominal voltage and apply to all valid processor bus frequencies and config-
urations. 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 3-2 on page 7) while running the Dhrystone 2.1 benchmark and achieving 2.3 Dhrystone MIPs/MHz
with one core at 100% efficiency and the second core at 65% efficiency.
3. Thermal power is the average power measured at nominal core voltage (VDD_Coren) and maximum operating junction tem-
perature (see Table 3-2) while running the Dhrystone 2.1 benchmark and achieving 2.3 Dhrystone MIPs/MHz on both cores
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 3-2) while running a test which includes an entirely L1-cache-resident, contrived sequence of
instructions which keep all the execution units maximally busy on both cores.
5. These power numbers are for Part Number PC8641Dxx1000NX only. V
DD_Coren = 0.95V and VDD_PLAT = 1.05V.
