SUPPLY CURRENT CHARACTERISTICS (Cont’d)
13.4.3 HALT Mode
13.4.4 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
source current consumption. To get the total de
-
vice consumption, the two current values must be
added (except for HALT mode).
13.4.5 On-Chip Peripherals
Notes:
1. Typical data are based on T
A
=25°C.
2. All I/O pins in input mode with a static value at V

terization results, tested in production at V

max.
3. Data based on characterization results, not tested in production.
4. Data based on characterization results done with the external components specified in Section 13.5.3 and Section
13.5.4, not tested in production.
5. As the oscillator is based on a current source, the consumption does not depend on the voltage.
6. Data based on a differential I
DD
measurement between reset configuration (timer counter running at f
CPU
/4) and timer
counter stopped (selecting external clock capability). Data valid for one timer.
7. Data based on a differential I
DD
measurement between reset configuration and a permanent SPI master communica-
tion (data sent equal to 55h).
8. Data based on a differential I
DD
measurement between reset configuration and I2C peripheral enabled (PE bit set).
9. Data based on a differential I
DD
measurement between reset configuration and continuous A/D conversions.
