Cyclone V V GT FGPA development board

[Martin_1]

Hi, this is with reference to the cyclone V FT FPGA development board (5CGTFD9E5F35C7N). I would like to know if the VCCIO 2.5V can be modified higher for bank 8 as currently 2.5V (C5_2.5V) is also used to power the FPLL, VCCBAT, VCC_AUX,VCC_PGM. If so, what is the highest power I can modify as I understand the some like FPLL has absolute max of 3.25V?

Hi,

For voltage level please refer to Cyclone V Device Datasheet and Cyclone® V Device Family Pin Connection Guidelines.

This device (5CGTFD9E5F35C7N) belongs to Cyclone GT series.

From datasheet VCCIO varies from 1.2V to 3.3V and you can change it.

However VCCA_FPLL is set to 2.5V

You can get it also from Pin Connection Guidelines

We do not suggest using device under Absolute Maximum Ratings. 

And for voltage regulator sharing, please refer to Pin Connection Guidlines
