Document Table of Contents Non-Voltage-Referenced I/O Standards

Each Arria® V I/O bank has its own VCCIO pins and supports only one VCCIO of 1.2, 1.25, 1.35, 1.5, 1.8, 2.5, 3.0, or 3.3 V 15. An I/O bank can simultaneously support any number of input signals with different I/O standard assignments if the I/O standards support the VCCIO level of the I/O bank.

For output signals, a single I/O bank supports non-voltage-referenced output signals that drive at the same voltage as VCCIO. Because an I/O bank can only have one VCCIO value, it can only drive out the value for non-voltage-referenced signals.

For example, an I/O bank with a 2.5 V VCCIO setting can support 2.5 V, 3.0 V and 3.3 V inputs but supports only 2.5 V output.

15 Arria V GZ devices do not support 3.3 V
