5.2.3
In this chip, the power distribution is divided into three segments.
The outputs of internal voltage regulators, LDO and VDD33, require an external capacitor which
should be located close to the corresponding pin. Figure 5-2 shows the power distribution of
NuMicro™ NUC120/NUC140 and Figure 5-3 shows the power distribution of NuMicro™ NUC100/
NUC130
System Power Distribution
NuMicro™ NUC100 Series Technical Reference Manual
Analog power from AVDD and AVSS provides the power for analog components
operation.
Digital power from VDD and VSS supplies the power to the internal regulator which
provides a fixed 2.5V power for digital operation and I/O pins.
USB transceiver power from VBUS offers the power for operating the USB
transceiver. (For NuMicro™ NUC120/NUC140 Only)
