Pin No.

Name

Type

Description

VREGIN

POWER

input

+5.0V or 3V3 power supply input.

VCCA

POWER

output

+1.8V output. Should not be used. Terminate with 0.1uF

capacitor to GND

VCORE

POWER

output

+1.8V output. Should not be used. Terminate with a 0.1uF

capacitor to GND

VCCD

POWER

output or

input

+3.3V output or input.

12, 24, 46

VCCIO

POWER

input

+3.3V input. I/O interface power supply input

VPLL

POWER

Input

+3.3V input. Internal PLL power supply input. It is

recommended that this supply is filtered using an LC filter.

(See figure 6.1)

VPHY

POWER

Input

+3.3V input. Internal USB PHY power supply input. Note that

this cannot be connected directly to the USB supply. A +3.3V

regulator must be used. It is recommended that this supply is

filtered using an LC filter.(See figure 6.1)

AGND

POWER

Input

0V Ground input.

10,11,22,23,35,36,47,48

GND

POWER

Input

0V Ground input.

Table 3.1 Power and Ground

** If pin 40 (VREGIN) is +5.0V, pin 39 becomes an output and If pin 40 (VREGIN) is 3V3 pin 39 becomes

an input.
