Hi, Can I supply the CY8C58LP with different voltage levels on VDDA (5.0V) and VDDD(3.3V)?
I need to have 3.3V logic on GPIO while having analog peripherals on 5.0V in order to achive  4V on DAC.
Will it work or damage the device?
Couldn't find exact answer on datasheet, it says (in the note*) that VDDA must be greater than or equal to all other supplies. Are they connected somehow? 

Thanks for the answer
Best Regards
Krystian

You can have different supply voltages (even different voltages per IO bank), as long as the analog supply voltage is not lower than any other supply voltage (they can be the same, though).
