I'm implementing a design with PSoC3 and I need overvoltage protecion in some of the input stages. More specifically a protection of 100Vdc. Does somebody know whether PSoC3 has any isolation or protection in its input/output pins?
As per datasheet the highest voltage on any pins on the PSoC device is same as the Vddios which have a limit of about 6V. The SIOs can tolerate upto 7V. But if you are expecting a protection for high voltage ESD that might be a different spec in the datasheet.
