Analog-to-Digital Converter (ADC) reference.
Dual Power Supply
Refer to
For decoupling recommendations for VDDIO, VDDANA, VDDCORE and VDDPLL, please refer
to the Schematic checklist.
In case of dual power supply, VDDIN and VDDOUT should be connected to ground to prevent
from leakage current.
To avoid over consumption during the power up sequence, VDDIO and VDDCORE voltage dif-
ference needs to stay in the range given
Figure 5-3.
The ADC reference (ADVREF) must be provided from an external source. Two decoupling
capacitors must be used to insure proper decoupling.
Figure 5-4.
Refer to
In case ADC is not used, the ADVREF pin should be connected to GND to avoid extra
consumption.
