Hello guys!
I currently working on a dmx desk board witch have a STPCD0175BTC3 processor in it... But i doesn't boot! I doesn't do any thing!
After a few hours of measuring everything I found that one of the RAM address lines is behaving strangely...
In attachment is a print screen of my crappy PC Oscilloscope, as you can see, when power is connected, data have a max voltage around 3.3v, but after some time it doesn't go higher that 1.6v...
Do you think the processor is faulty, or should I look somewhere else??
Thanks!
