NuMicroï¤ M0518 Series Datasheet
6.2.3 System Power Distribution
In this chip, the power distribution is divided into three segments.
ï¬ Analog power from AVDD and AVSS provides the power for analog components
operation.
ï¬ Digital power from VDD and VSS supplies the power to the internal regulator which
provides a fixed 1.8 V power for digital operation and I/O pins.
The outputs of internal voltage regulators, LDO, require an external capacitor which should be
located close to the corresponding pin. Analog power (AVDD) should be the same voltage level
with the digital power (VDD). Figure 6-2 shows the NuMicroï¤ M0518 power distribution.
