1. The analog supply current is the sum of the active or disabled current for each of the analog modules on the device. See
each module's specification for its supply current.
2. 100MHz core and system clock, 50MHz bus and FlexBus clock, and 25MHz flash clock . MCG configured for FEI mode.
All peripheral clocks disabled.
3. 100MHz core and system clock, 50MHz bus and FlexBus clock, and 25MHz flash clock. MCG configured for FEI mode. All
peripheral clocks enabled.
4. Max values are measured with CPU executing DSP instructions.
5. 25MHz core and system clock, 25MHz bus clock, and 12.5MHz FlexBus and flash clock. MCG configured for FEI mode.
6. 2 MHz core, system, FlexBus, and bus clock and 1MHz flash clock. MCG configured for BLPE mode. All peripheral clocks
disabled. Code executing from flash.
7. 2 MHz core, system, FlexBus, and bus clock and 1MHz flash clock. MCG configured for BLPE mode. All peripheral clocks
enabled but peripherals are not in active operation. Code executing from flash.
8. 2 MHz core, system, FlexBus, and bus clock and 1MHz flash clock. MCG configured for BLPE mode. All peripheral clocks
disabled.
9. Data reflects devices with 128 KB of RAM. For devices with 64 KB of RAM, power consumption is reduced by 2 μA. For
devices with 32 KB of RAM, power consumption is reduced by 3 μA.
10. Includes 32kHz oscillator current and RTC operation.
5.2.5.1 Diagram: Typical IDD_RUN operating behavior
The following data was measured under these conditions:
MCG in FBE mode for 50 MHz and lower frequencies. MCG in FEE mode at greater
than 50 MHz frequencies.
USB regulator disabled
No GPIOs toggled
Code execution from flash with cache enabled
For the ALLOFF curve, all peripheral clocks are disabled except FTFL
