SUPPLY CURRENT CHARACTERISTICS (Cont’d)
16.4.3 HALT and ACTIVE-HALT Modes
16.4.4 Supply and Clock Managers
The previous current consumption specified for
the ST7 functional operating modes over tempera-
ture range does not take into account the clock
16.4.5 On-Chip Peripherals
Notes:
1. Typical data are based on T
2. All I/O pins in input mode with a static value at V
terization results, tested in production at V
3. Data based on design simulation and/or technology characteristics, not tested in production. All I/O pins in input mode
with a static value at V
4. Data based on characterization results, not tested in production.
5. Data based on characterization results done with the external components specified in
16.5.4, not tested in production.
6. As the oscillator is based on a current source, the consumption does not depend on the voltage.
7. Data based on a differential I
counter stopped (selecting external clock capability). Data valid for one timer.
8. Data based on a differential I
tion (data sent equal to 55h).
9. Data based on a differential I
