Are the bi-directional I/O port pins on the FX2LP 5 volt tolerant?
The CY7C68013 is a 3.3V device. The "features" page of the manual says that its inputs are "5V tolerant", but the "absolute maximums" chapter is somewhat ambiguous - it says 5.25V for inputs and Vcc+0.5V for outputs in high-Z state. Every bi-directional port pin, when used as an input, is also an output in high-Z state, so I'm not sure... any help would be appreciated.
