SUPPLY CURRENT CHARACTERISTICS (Cont’d)

13.4.2 HALT and ACTIVE-HALT Modes

13.4.3 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. All I/O pins in output mode with a static value at VSS (no load), CSS and LVD disabled. Data based on characterization

results, tested in production at VDD max. and fCPU max.

2. Data based on characterisation results, not tested in production. All I/O pins in output mode with a static value at VSS

(no load); clock input (OSC1) driven by external square wave, LVD disabled. To obtain the total current consumption of

the device, add the clock source consumption (Section 13.5.3 and Section 13.5.4).

3. 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.

4. As the oscillator is based on a current source, the consumption does not depend on the voltage.
