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).

Note 1:

Typical data are based on TA=25°C and not tested in production

Note 2:

Oscillator and watchdog running.

All others peripherals disabled.

Note 3:

USB Transceiver and ADC are powered down.

Note 4:

Low voltage reset function enabled.

CPU in HALT mode.

Current consumption of external pull-up (1.5Kohms to USBVCC) and pull-down (15Kohms to VSSA)

not included.
