11.1.10.2 System Power Consumption in Applicative Use Cases

Table 11-75 provides the processor power consumption in the following conditions:
  • fCPU_CLK = 800 MHz
  • fMCK1 = 200 MHz
  • fMCK2 = 133 MHz
  • fMCK3 = 266 MHz
  • fMCK4 = 400 MHz
  • fMCK5 = 200 MHz
  • fMCK6 = 200 MHz
  • fMCK7, MCK8, MCK9 = 100 MHz
  • I & D caches are enabled.
  • The external SDRAM memory is DDR3L.
  • Use cases are run on Linux®.
  • Current consumptions are measured according to the figure below. Note that current consumptions of external components (DDR3L, Gigabit Ethernet PHY, etc.) are counted.
  • The ambient temperature is 25°C.
