1.2V digital core voltage output (internal 1.2V LDO power supply output), this

1.2V output ball provides power to all VDDC/VDDA balls. It is recommended this

ball should be connected to 3.3V power rail by a 100 ohm resistor for the internal

LDO application.

Note: Internally generated power voltage. Do not connect an external power

supply to this ball. This ball is used for connecting external filter (Ferrite bead

and capacitors).

1.2V digital core VDD input power supply from VDDCO (ball C4) through external

Ferrite bead and capacitor.

1.2V analog VDD input power supply from VDDCO (ball C4) through external

Ferrite bead and capacitor.

3.3V analog VDD input power supply with well decoupling capacitors.

3.3V analog VDD input power supply with well decoupling capacitors.

3.3V digital VDDIO input power supply for IO with well decoupling capacitors.
