3. Internal Regulator, Power-ON Reset and RC oscillator
3.1. Regulator
The internal voltage regulator input 3.3V and output 1.8V used for core power supply as shown in Figure 3.
3.2. Power-on-reset and brown-out-reset
The internal reset control unit has power-on-reset (POR). To use internal POR, only provide 3.3V to VDDA33
and GNDA connected to ground as shown in Figure 3.
3.3. RC oscillator
An integrated RC oscillator can be used to reduce BOM cost. ROSC must be connected to 1.8V through a
resistor, as shown in Figure 3.
