Description
3.3 V regulator supply voltage: This is the power supply for
the on-chip voltage regulator that supplies internal logic.
Analog 3.3 V pad supply voltage: This can be connected to
the same supply as V
noise and error. This voltage is used to power the ADC and
DAC. Note: this pin should be tied to 3.3V if the ADC and
DAC are not used.
3.3 V supply voltage: This is the power supply voltage for I/O
other than pins in the VBAT domain.
ADC positive reference voltage: This should be the same
voltage as V
error. The voltage level on this pin is used as a reference for
ADC and DAC. Note: this pin should be tied to 3.3V if the
ADC and DAC are not used.
Ground: 0 V reference for digital IO pins.
Ground: 0 V reference for internal logic.
Analog ground: 0 V power supply and reference for the ADC
and DAC. This should be the same voltage as V
be isolated to minimize noise and error.
Input to the oscillator circuit and internal clock generator circuits.
Output from the oscillator amplifier.
