+1.8V input. Core supply voltage input
+3.3V input. I/O interface power supply input. Failure to connect all
VCCIO pins will result in failure of the device.
+3.3V input. Internal PHY PLL power supply input. It is recommended
that this supply is filtered using an LC filter.
+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.
+3.3V Input. Integrated 1.8V voltage regulator input.
+1.8V Output. Integrated voltage regulator output. Connect to VCORE
with 3.3uF filter capacitor.
0V Analog ground.
0V Ground input.
