JTAG supply voltage and USB blaster 2/EPCQ-1

Hello, I am trying to implement JTAG connection with PCB. I intent to use USB blaster to program the FPGA. In the handbook (cyclone 10 LP) it says "For device using VCCIO of 2.5, 3.0, and 3.3 V, all...

Hi aakku,

If you refer to the Cyclone 10 LP pin guideline, JTAG pins need to connect it to VCCA which is 2.5V. otherwise, I'm not guarantee it will work.

Yes, EPCQ-A device can use to store configuration data.

Thanks

Thank you!

Some development boards' datasheet show 3.3V connected to JTAG for some reason. That's why U wanted to make sure.

Thanks for confirming that.
