Function
Analog Ground. This pin should be connected directly to the
ground plane.
Digital Ground. This pin should be connected directly to the
ground plane.
Analog Power Supply. A 3.3 V power supply should be
connected to this pin. V3P3A must be the same voltage as
V3P3SYS.
System 3.3 V Supply. This pin should be connected to a 3.3 V
power supply.
Auxiliary Voltage Output of the Chip. In mission mode, this
pin is connected to V3P3SYS by the internal selection switch.
In BRN mode, it is internally connected to VBAT. V3P3D is
floating in LCD and sleep mode. A bypass capacitor to ground
should not exceed 0.1 μF.
Output of the 2.5 V Regulator. This pin is powered in MSN and
BRN modes. A 0.1 μF bypass capacitor to ground should be
connected to this pin.
Output of the LCD DAC. A 0.1 μF bypass capacitor to ground
should be connected to this pin.
Battery Backup Pin to Support the Battery Modes (BRN, LCD).
A battery or super capacitor is to be connected between VBAT
and GNDD. If no battery is used, connect VBAT to V3P3SYS.
RTC and Oscillator Power Supply. A battery or super-capacitor
is to be connected between VBAT and GNDD. If no battery is
used, connect VBAT_RTC to V3P3SYS.
