10.1.8.1 Power Consumption in Active Mode

Table 10-61 provides the processor power consumption in the following conditions:

f_{CPU_CLK} = from 200 MHz to 800 MHz
f_MCK = 100 MHz to 266 MHz
L1 caches enabled
The Arm926EJ-S core executes a Coremark benchmark from the (internal) SRAM0
Code compiled with speed optimization
Peripheral clocks disabled
Current measured as per Figure 10-41
