How can I get 5.0V FPGA digital signal output?

Hello, everyone. My name is Ray. My device is Max 7000 series, EPM7128SLC84-7. I need 5.0V timing clock, and I set all vccio and vccint at a level at 5.0V power supply. However, ...

Thank you, FvM.

In the datashht " Max 7000 Programmable Logic Device Family ",

In page 20, it shows that "The VCCIO pins can be connected to either a 3.3-V or a 5.0-V power supply, depending on the output requirement."

I just wonder how to set the VCCIO pins.

I 've checked the output again, and output is at a level 3.3V(digital timing clock).

The hole number for VCC is 5.0V under measurement.

Thanks for kind reply.

Ray
