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).
Notes:
1. Typical data are based on TA = 25°C, VDD = 5V (4.5V ≤ VDD ≤ 5.5V range).
2. Data based on characterization results, tested in production at VDD max., fCPU max. and TA max.
3. Measurements are done in the following conditions:
- Program executed from Flash, CPU running with Flash (for flash devices).
- 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.
- In SLOW and SLOW WAIT mode, fCPU is based on fOSC divided by 32.
To obtain the total current consumption of the device, add the clock source (
Section 12.5.3) and the peripheral power
4. All I/O pins in input mode with a static value at VDD or VSS (no load). Data based on characterization results, tested in
production at VDD max., fCPU max. and TA max.
5. This consumption refers to the Halt period only and not the associated run period which is software dependent.
