FPGA with most High Dynamic (HD) or High Range (HR) I/O

Jump to solution

Hi, 

For this particular application that I am working, I am not much concerned about using high end FPGA products. 

I am more concerned in driving as many I/O possible at 3.3 volts. 

I noticed the more recent FPGAs are all moving to more High Performance (HP) I/O. 

What are some of the parts with high number of HD or HR I/O ? Or is there anyway that can run High Performance (HP) I/Os at 3.3 Volts? Maybe there are some tweaks or some setting that allows to run HP at 3.3 Volts? 

Thanks, 

--Rudy

You must be looking at 16nm US+.
Starting on 7 series, the HP I/O are designed for high speed DDR memory and LVDS applications... They don't support the wider voltage ranges.

If you have a lot of 3.3V requirements, I'd generally start with Spartan-7 or Artix-7 (the latter have GTPs for high speed serial too).

But there's a few Kintex-7 parts like the 7K480T/7K420T that are all HP too:
