3.21.2
Internal voltage reference (VREFINT)
The internal voltage reference (VREFINT) provides a stable (bandgap) voltage output for
the ADC and the comparators. The VREFINT is internally connected to the ADC1_IN0 input
channel. The precise voltage of VREFINT is individually measured for each part by ST
during production test and stored in the system memory area. It is accessible in read-only
mode.
3.21.3
VBAT battery voltage monitoring
This embedded hardware enables the application to measure the VBAT battery voltage using
the internal ADC channel ADC1_IN18. As the VBAT voltage may be higher than the VDDA,
and thus outside the ADC input range, the VBAT pin is internally connected to a bridge
divider by 3. As a consequence, the converted digital value is one third of the VBAT voltage.
