Pin No.

Name

Type

Description

12,37,64

VCORE

POWER

Input

+1.8V input. Core supply voltage input

20,31,42,56

VCCIO

POWER

Input

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

connect all VCCIO pins will result in failure of the device.

VPLL

POWER

Input

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

recommended that this supply is filtered using an LC filter.

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.

VREGIN

POWER

Input

+3.3V Input. Integrated 1.8V voltage regulator input.

VREGOUT

POWER

Output

+1.8V Output. Integrated voltage regulator output. Connect to

VCORE with 3.3uF filter capacitor.

AGND

POWER

Input

0V Analog ground.

1,5,11,15,

25,35,47,51

GND

POWER

Input

0V Ground input.
