Are FM Rcv.Breakout Board I/O Pins 5 Volt Tolerant?

I have the AR1010-based FM Breakout Board. Can the I/O pins tolerate 5 volts? If not any suggestions on how to do this without a level shifting chip? I will be using a Basic Stamp 2 micro. The register table for this device looks incomplete. This could be fun…

Have you checked the AR1010 data sheet?

The datasheet reads ambiguous on it to me.

One reading suggests 5V IO is okay, but then it says 3.6V max for VCCIO. Probably best to stick to 3.3V logic, or use a pair of resistors as a voltage divider, on each pin.

Thank you.
