Supply and clock managers

The previous current consumption specified for the ST7 functional operating modes over

temperature range does not take into account the clock source current consumption. To

obtain the total device consumption, the two current values must be added (except for HALT

mode).

Typical data are based on TA = 25°C, VDD =5V (4.5V ≤VDD ≤5.5V range).

Data based on characterization results, tested in production at VDD max., fCPU max. and TA max.

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 20.5.1: Crystal and ceramic resonator

oscillators) and the peripheral power consumption (Section 20.4.2: On-chip peripherals).

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.

This consumption refers to the Halt period only and not the associated run period which is software dependent.
