SUPPLY CURRENT CHARACTERISTICS (Cont’d)
11.4.4 Supply and Clock System
The previous current consumption specified for
the ST6 functional operating modes over tempera-
ture range does not take into account the clock
source current consumption. To get the total de-
vice consumption, the two current values must be
added (except for STOP mode).

Notes:
1. Typical data are based on TA=25°C.
2. Data based on characterization results, not tested in production.
3. Data based on a differential IDD measurement between reset configuration (OSG and LFAO disabled) and LFAO run-
ning (also includes the OSG stand alone consumption).
4. Data based on a differential IDD measurement between reset configuration with OSG disabled and OSG enabled.
5. Data based on a differential IDD measurement between reset configuration with LVD disabled and LVD enabled.
6. Data based on a differential IDD measurement between reset configuration (timer disabled) and timer running.
7. Data based on a differential IDD measurement between reset configuration and continuous A/D conversions.
