Do Intel® Max® 10, Intel® Cyclone® 10, Intel® Arria® 10 and Intel® Stratix® 10 devices feature Multi-Volt I/O support for the general purpose input/output (GPIO) pins?

Description

Intel® Max® 10, Intel® Cyclone® 10, Intel® Arria® 10, and Intel® Stratix® 10 devices do not support the Multi-Volt I/O capability of the GPIO pins that are featured for in previous members of these product families.

Instead, use an assignment to select the I/O signal standard, which must be compatible with the VCCIO for that I/O. The required input and output voltage levels of each GPIO signal standard are shown in the I/O Standard Specifications of the datasheet for each device:
