Is there any way the Cyclone 10LP can be used without powering VCCA

VCCA must have 2.5V (+/- 5%) applied to it even if you're not using the PLLs. Whether you need a 2.5V power supply on board to supply that is a question worth asking. Assuming you have a higher voltage regulator you could potentially pot-down with two resistors to bias the pin at 2.5V. This relies on a stable rail that's not going to vary beyond 5%.

 

However, I wouldn't advocate doing this. For the sake of a very cheap linear regulator and ceramic cap, I'd add a dedicated power supply for peace of mind.

 

Cheers,

Alex

Hi , Kindly find the C10 pcg in that it is mentioned in the page no:9 https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/dp/cyclone-10/pcg-01021.pdf To connect to the VCCA,I am strongly recommend to you to connect the VCCA for proper working of FPG.
