13.4 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).

13.4.1 RUN Mode

Figure 75. Typical IDD in RUN vs. fCPU

Notes:

1. Typical data are based on TA=25°C, VDD=5V (4.0V≤VDD≤5.5V range) and VDD=3.3V (2.7V≤VDD≤4.0V range).

2. Data based on characterization results, tested in production at VDD =5.5V. and fCPU = 8MHz

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

in reset state; clock input (OSC1) driven by external square wave, LVD disabled.
