12.5.2 FLASH CURRENT CONSUMPTION

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 12.6.3) and the peripheral power

consumption (Section 12.5.4).

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.

4. Data based on

characterisation 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).
