15.4 SUPPLY CURRENT CHARACTERISTICS
The following current consumption specified for
the ST7 functional operating modes over tempera-
ture range does not take into account the clock
source current consumption. To get the total de-
15.4.1 Run and Slow Modes
Figure 62. Typical I
Notes:
1. Typical data is based on T
2. Data based on characterization results, tested in production at V
3. CPU running with memory access, all I/O pins in input mode with a static value at V
in reset state; clock input (OSC1) driven by external square wave, CSS and LVD disabled.
4. Slow mode selected with f
(no load), all peripherals in reset state; clock input (OSC1) driven by external square wave, CSS and LVD disabled.
