- Aug 14, 2014There is nothing wrong with pin 1 voltage....The voltages you gave are right where they should be...'Has nothing to do with R7N or R8NProceed!Bruce
I was more concerned earlier. since I has forgot install R7N and R8N.. I did some research and found K5RD notes .. I mention this because it helped me by alerting my attention to this ...
and it throws the amp and IC2G and IC3G voltages off..
I am still concerned about pin one voltage .. and my counter is not triggering right so I can't measure the frequency.. But how far off can it be with a crystal controlling it ... I did try to put my old scope on it but it would not sync to measure the period... oh well off to the next phase
Thanks for your earlier response...

I need some help ! I am not getting what I am suppose to have....verified components installed OK ..(any suggestions on flux cleaner, I think I need something better)
Stage 3 strange voltage on pin1 of Si Labs 570
here is what I have on SiLabs 570
pin 1- 3.2 v
pin 2- 3.2v
pin 3- 0
pin 4- 1.19v
pin 5- 1.19v
pin 6- 3.2v
pin 7- 3.28v
pin 8- 3.28v
on R5G Left to Right 3.22v, 3.3v
I have had experience putting this same chip in in the past with no problems could I have another component in wrong .. I did look it all over but I could have missed something... any Ideas...
