Digital Power Supply - Core. +3.3V supply
for core digital circuits.
Digital Power Supply - I/O Ring. +3.3V
supply for digital I/O circuits. Regardless of
the IO supply, digital I/O pins remain tolerant
of 5V signal levels.
Analog Power Supply. +3.3V supply for all
analog receive circuits.
Analog Power Supply. +3.3V supply for all
analog transmit circuits.
Digital Ground. Ground return for both core
and I/O digital supplies (VCCD and VCCIO).
All ground pins can be tied together using a
single ground plane.
Analog Ground. Ground return for analog
supply. All ground pins can be tied together
using a single ground plane.
Substrate Ground. Ground for chip
substrate. All ground pins can be tied
together using a single ground plane.
