Supply current in Run mode(2)
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
fOSC = 2 MHz, fCPU =1MHz
fOSC = 4 MHz, fCPU =2MHz
fOSC = 8 MHz, fCPU =4MHz
