Notes:

1. Data based on characterization results, tested in production at VDD max. and fCPU max.

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 mode, fCPU is based on fOSC divided by 32.

To obtain the total current consumption of the device, add the clock source (Section 12.5.3) and the peripheral power

consumption.
