12.4 SUPPLY CURRENT CHARACTERISTICS
The following 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 for which the clock
is stopped).
12.4.1 RUN and SLOW Modes
Figure 69. Typical IDD in RUN vs. fCPU
Figure 70. Typical IDD in SLOW vs. fCPU
Notes:
1. Typical data are based on TA=25°C, VDD=5V (4.5V≤VDD≤5.5V range) and VDD=3.3V (3V≤VDD≤3.6V range).
2. Data based on characterization results, tested in production at VDD max. and fCPU max.
3. CPU running with memory access, all I/O pins in input mode with a static value at VDD or VSS (no load), all peripherals
switched off; clock input (OSC1) driven by external square wave, LVD disabled.
4. SLOW mode selected with fCPU based on fOSC divided by 32. All I/O pins in input mode with a static value at VDD or
VSS (no load), all peripherals switched off; clock input (OSC1) driven by external square wave, LVD disabled.
