11.4 SUPPLY CURRENT CHARACTERISTICS

The following current consumption specified for

the ST6 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 STOP mode for which the clock

is stopped).

11.4.1 RUN Modes

Notes:

1. Typical data are based on TA=25°C, VDD=5V (4.5V≤VDD≤6.0V range) and VDD=3.3V (3V≤VDD≤3.6V range).

2. Data based on characterization results, tested in production at VDD max. and fOSC max.

3. CPU running with memory access, all I/O pins in input with pull-up mode (no load), all peripherals in reset state; clock

input (OSCIN) driven by external square wave, OSG and LVD disabled, option bytes not programmed.
