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
source current consumption. To get the total de-
vice consumption, the two current values must be
added (except for HALT mode).
16.4.5 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
or V
SS
(no load), CSS and LVD disabled. Data based on charac-
terization results, tested in production at V
DD
max. and f
CPU
max.
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
DD
or V
SS
(no load); clock input (OSC1) driven by external square wave, LVD disabled.
4. Data based on characterization results, not tested in production.
5.
Data based on characterization results done with the external components specified in
Section 16.5.3
and
Section
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
measurement between reset configuration (timer counter running at f
CPU
/4) and timer
counter stopped (selecting external clock capability). Data valid for one timer.
8. Data based on a differential I
DD
measurement between reset configuration and a permanent SPI master communica-
tion (data sent equal to 55h).
9. Data based on a differential I
DD
measurement between reset configuration and continuous A/D conversions.
