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-

added (except for STOP mode for which the clock
is stopped).

Notes:
1. Typical data are based on T_A=25°C, V_DD=5V (4.5V≤V_DD≤6.0V range) and V_DD=3.3V (3V≤V_DD≤3.6V range).
2. Data based on characterization results, tested in production at V_DD max. and f_OSC 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 (OSC_IN) driven by external square wave, OSG and LVD disabled, option bytes not programmed.
