VCC(I/O)[3] 48

-

supply voltage; used to supply voltage to the I/O pads; see

Section 8.14

VBUS

49

A

USB bus power pin sensing input; used to detect whether

the host is connected or not; it is an output for VBUS pulsing

in OTG mode; when VBUS is not detected, pin RPU is

internally disconnected from pin DP in approximately 4 ns;

connect a 1 µF electrolytic capacitor and a 1 MΩ pull-down

resistor to ground; see Section 8.12

5 V tolerant

VCC(1V8)[3] 50

-

regulator output voltage (1.8 V ± 0.15 V); tapped out voltage

from the internal regulator; this regulated voltage can drive

external devices up to 1 mA; decouple this pin using 4.7 µF

and 0.1 µF capacitors; see Section 8.14

XTAL2

51

O

crystal oscillator output (12 MHz); connect a fundamental

parallel-resonant crystal; leave this pin open-circuit when

using an external clock source on pin XTAL1; see Table 83

XTAL1

52

I

crystal oscillator input (12 MHz); connect a fundamental

parallel-resonant crystal or an external clock source (leaving

pin XTAL2 unconnected); see Table 83

VCC[3]

53

-

supply voltage (3.3 V ± 0.3 V); this pin supplies the internal

voltage regulator and the analog circuit; see Section 8.14

VCC[3]

54

-

supply voltage (3.3 V ± 0.3 V); this pin supplies the internal

voltage regulator and the analog circuit; see Section 8.14
