6.2.3 System Power Architecture
In this device, the power architecture is divided into three segments.
ï® Analog power from AVDD and AVSS provides the power for analog module operation.
ï® Digital power from VDD and VSS supplies the power to the internal regulator which
provides a fixed 1.8V power for digital operation and I/O pins.
The outputs of internal voltage regulator, which is LDO, require an external capacitor which
should be located close to the corresponding pin. The Figure 6-2 shows the power architecture of
this device.
