Name

Type

Description

VCC1V2

+1.2V core voltage.

This is internal regulator output and core voltage

input. Connect 4.7uF and 0.1uF decoupling

capacitors to GND.

VUSB3V3

+3.3V supply voltage.

This is the supply voltage for USB Device I/O ports.

Connect 10uF and 0.1uF decoupling capacitors. This

pin can be connected to all +3.3V power supply pins

without the 10uF capacitor.

D_DM

AI/O

USB Device bidirectional DM line.

D_DP

AI/O

USB Device bidirectional DP line.

DRREF

USB Device reference voltage input.

Connect 12k ohm +/- 1% resistor to GND.

ADC3

8-bit A/D converter 3, input.

ADC2

8-bit A/D converter 2, input.

ADC1

8-bit A/D converter 1, input.

ADC_REFP

ADC positive reference voltage.

VCC3V3A

+3.3V supply voltage.

This is the supply voltage for Analog I/O ports.

Connect 10uF and 0.1uF decoupling capacitors. This

pin can be connected to all VCC3V3 pins without the

10uF capacitor.

AGND

Analog Ground.

DAC_REFP

DAC positive reference voltage.

DAC1

10-bit D/A converter 1, output.

DAC0

10-bit D/A converter 0, output.

I2CM_SCL/I2CS_SCL/

GPIO12

I/O

I2CM_SDA/I2CS_SDA/

GPIO13

I/O

GPIO13 input/output. (By default is GPIO input,

internal pull-low)

I2C master data line input/output.

I2C slave data line input/output.
