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).

Notes:

1. Typical data are based on TA=25°C.

2. All I/O pins in input mode with a static value at VDD or VSS (no load), CSS and LVD disabled. Data based on charac-

terization results, tested in production at VDD max. and fCPU 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 VDD or VSS (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 IDD measurement between reset configuration (timer counter running at fCPU/4) and timer

counter stopped (selecting external clock capability). Data valid for one timer.

8. Data based on a differential IDD measurement between reset configuration and a permanent SPI master communica-

tion (data sent equal to 55h).

9. Data based on a differential IDD measurement between reset configuration and continuous A/D conversions.
