Name

Type

Description

Not connected.

VCC1V2

+1.2V core voltage.

This is internal regulator output and core voltage

input. Connect 4.7uF and 0.1uF decoupling

capacitors to GND.

VCCIO3V3

+3.3V supply voltage.

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

Connect a 0.1uF decoupling capacitor.

XI/CLKIN

12MHz clock frequency. Input to the Oscillator

circuit.

XIO

AI/O

Output from the Oscillator amplifier. Input to the

internal clock generator circuit.

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.

Not connected.

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.

Not connected.
