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.
4
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.
