Cyclone III EP3C10F256C6N input pin voltage range?

Hello,  

 

I have already design a Cyclone III EP3C10F256C6N test pcb board. 

 

VCCIO1 connect to 1.8V 

Some application will input logic high 3.3V to Bank VCCIO1 IO pin.  

Is possible broken the VCCIO1 IO pin? 

Can the VCCIO1 IO pin decode the 3.3V logic high and 0V low? 

 

Thanks for help

Refer to the 'cyclone iii device datasheet (https://www.altera.com/en_us/pdfs/literature/hb/cyc3/cyc3_ciii52001.pdf)'. Look at tables 1-1 & 1-2. 

 

You should be fine. 

 

Cheers, 

Alex
