VCC_PLL
VCC
Supply
Supply
VCC PLL positive power supply (analog power supply). It is recommended to use an external RC
filter for the analog power supply pin VCC_PLL. Please see applications section for details.
VCC Positive power supply for I/O and core. All VCC pins must be connected to the positive power
supply for correct operation
