SUPPLY CURRENT CHARACTERISTICS (Cont’d)
12.4.5 HALT and ACTIVE-HALT Modes
Notes:
1. All I/O pins in push-pull 0 mode (when applicable) with a static value at V
Data based on characterization results, tested in production at V
2. Data based on characterisation results, not tested in production. All I/O pins in push-pull 0 mode (when applicable) with
a static value at V
total current consumption of the device, add the clock source consumption
12.4.6 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 get the total device consump-
tion, the two current values must be added (except for HALT mode).
Notes:
1. Data based on characterisation results, not tested in production.
2. Data based on characterization results done with the external components specified in
12.5.4, not tested in production.
3. As the oscillator is based on a current source, the consumption does not depend on the voltage.
