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.
