I am having an issue with P1 on my on my ICE. This is a Circa 2004 ICE with a SMT chip mounted on a flex tape. It has been flawless. I think I might have injured it somehow. It seems P1 doesn't work. Everthing else O.K. Doesn't seem to work as either in or out. Has anybody else had any issues with this ? This is the Xout/Sdata/P1 pin. I have done many things with it over the years with many configurations, so I am not completely sure if this is a new problem or not. I am using designer 5.4.
Yes, I admit that I have blown P1 on my POD for a CY8C29466. Probably by tampering somewhere with a probe. I am quite sure that I would habe blown a normal PSoC1 as well.
I was hoping perhaps there was a emulator config issue with this pin. Too bad because it is some of my personal stuff I am using for work.
I wish they still sold the old style flex cable implmentation. The new ones with all the feet seem mechanically complex.
The pod looks a bit like one of the three "Towers of Hanoy", but I have soldered a 28-pin socket onto the board where the pod is plugged into. When there is no stress on the flex-cable everything runs smoothly.
The most common failure comes from connecting a PSoC GPIO to the gate of a power FET with no series resistor in between. When you probe the gate of the FET, you can slip and short gate to drain. If drain is connected to a load greater than Vdd=5.0V, then 'poof' goes the GPIO. I have seen this numerous times; we simply cannot protect the chip from massive over-voltage.
That said, send me your contact information by email to SEG@cypress.com and I'll find a replacement for you.
I, too, prefer the old style DIP flex circuit and still have a few around.
