14 years agoThank 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.
