Notes:
1. Data based on characterization results, tested in production at VDD max. and fCPU max.
2. Measurements are done in the following conditions:
- Progam 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 mode, fCPU is based on fOSC divided by 32.
To obtain the total current consumption of the device, add the clock source (Section 11.5.3) and the peripheral power
consumption.
