Re: Help ACEX1K & EPC2

I am sorry that you may make a mistake in your design. The VCCIO should be supplied by 3.3V, not 5V. IO of acex1k is 5v tollerance. It is not necessary to power the chip with 5V. Moreover, the max voltage of VCCIO is 4.6V It is dangerous to power the chip with the voltage higher than 4.6V.
 

Re: Help ACEX1K & EPC2

EPC2 need 3.3V suply,it is better to give both ACEX1K and EPC2 3.3V
