12.4 SUPPLY CURRENT CHARACTERISTICS
The following current consumption specified for the ST7 functional operating modes over temperature
range does not take into account the clock source current consumption. To get the total device consump-
tion, the two current values must be added (except for HALT mode for which the clock is stopped).
12.4.1 CURRENT CONSUMPTION
Notes:
1. Data based on characterization results, tested in production at V
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 V
- All peripherals in reset state.
- Clock input (OSC1) driven by external square wave.
- In SLOW and SLOW WAIT mode, f
3. All I/O pins in push-pull 0 mode (when applicable) with a static value at V
4. Data based on characterisation results, not tested in production. All I/O pins in push-pull 0 mode (when applicable) with
