11.4 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).
11.4.1 CURRENT CONSUMPTION
Notes:
1.
Data based on characterization results, tested in production at V
DD
max. and f
CPU
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 V
DD
or V
SS
(no load)
- All peripherals in reset state.
- LVD disabled.
- Clock input (OSC1) driven by external square wave.
- In SLOW and SLOW WAIT mode, f
CPU
is based on f
OSC
divided by 32.
To obtain the total current consumption of the device, add the clock source (
Section 11.4.2
) and the peripheral power
consumption (
Section 11.4.3
).
3. All I/O pins in push-pull 0 mode (when applicable) with a static value at V
DD
or VSS (no load), LVD disabled. Data
based on characterization results, tested in production at V
DD
max. and f
CPU
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 V
or V
(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 11.4.2
).
