Supply current in Run mode(2)

Measurements are done in the following conditions:

- Program executed from RAM, CPU running with RAM access. The increase in consumption when executing from Flash is

50%.

- All I/O pins in input mode with a static value at VDD or VSS (no load)

- All peripherals in reset state

- LVD disabled

- Clock input (OSC1) driven by external square wave

- In Slow and Slow Wait modes, fCPU is based on fOSC divided by 32

- To obtain the total current consumption of the device, add the clock source (Section 12.6.3) and the peripheral power

consumption (Section 12.5.4).

Supply current in Halt mode(3)

All I/O pins in push-pull 0 mode (when applicable) with a static value at VDD or VSS (no load), LVD disabled. Data based on

characterization results, tested in production at VDD max. and fCPU max.

Supply current in Active Halt

mode(4)

Data based on characterization results, not tested in production. All I/O pins in push-pull 0 mode (when applicable) with a

static value at VDD or VSS (no load); clock input (OSC1) driven by external square wave, LVD disabled. To obtain the total

current consumption of the device, add the clock source consumption (Section 12.6.3).
