I would like to know about the input protection capabilities for PSoC I/O pins. specifically are there any protection diodes on I/O pins of any PSoC IC.if so how much power they can handle.?
Most IC now have ESD protection on the pins, but I would use external clamping diodes in all IO's. For those IO's goes outside the board, and have chances of having some kinds of ESD, I would all TRANSORB type device as well.
