SUPPLY CURRENT CHARACTERISTICS (Cont’d)
10.4.4 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).
