Supply and clock managers
The previous current consumption specified for the ST7 functional operating modes over
temperature range does not take into account the clock source current consumption. To
obtain the total device consumption, the two current values must be added (except for Halt
mode).
Table 91.
1. Data based on characterization results done with the external components specified in
2. As the oscillator is based on a current source, the consumption does not depend on the voltage.
