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 Run and Slow modes (Flash devices)
Figure 131. Typical I
Notes:
1. Data based on characterization results, tested in production at V
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
- All peripherals in reset state.
- LVD disabled.
- Clock input (OSC1) driven by external square wave.
- In Slow and Slow-wait mode, f
