Max 10 supporting IO voltages

Hello Madhura,

10M40DAF484C8G device does support 1.0V LVCMOS I/O Standard. Do note that not all Max 10 devices support 1.0V I/O. You can refer on page 19 of this link for more information: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/max-10/m10_datasheet.pdf

This document can also be helpful for your design: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/max-10/ug_m10_gpio.pdf

Hope this answer helps.
