SUPPLY CURRENT CHARACTERISTICS (Cont’d)
12.4.2 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 characterization results done with the external components specified in Section 12.5.3 , not tested in
production.
2. As the oscillator is based on a current source, the consumption does not depend on the voltage.
