I am supplying this CPLD from two separate power rails (A 1.8V rail and a 3.3V rail). The CPLD uses 1.8V for VCCI02 through VCCI04, and uses the 3.3V rail for VCCI01. The 1.8V rail starts up in about 1ms, and the 3.3V rail starts up in about 20-40ms. Will the component have issues since the two supplies are not coming up to voltage simultaneously?

I think you can continue there since the answer will be similar.


Thank you
