10.1.9.1 Processor Power Consumption in Active Mode

Table 10-62 provides the processor power consumption in the following conditions:

  • fCPU_CLK = from 200 MHz to 800 MHz
  • fMCK = 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 the following figure
