Reading the datasheet of the FT232R from FTDI did not answer my question so I'm asking here:
I have the following configuration:
VCC: +5V VCCIO: +3.3V
The Part I'm unsure:
The datasheet of the FT232 states the following:
Integrated level converter on UART and CBUS for interfacing to between +1.8V and +5V logic.
and a maximum input voltage as:
IOmax = VCC + 0.5V
My question is:
Am I damaging the FT232 if my input high voltage is +5V on either RXD/TXD? Because I think I won't because of the stated ''feature'' but I want to be sure.
EDIT If you want a reason why I'm specifically asking then: sparkfun sells these FT232 adapters which can be either 3.3V or 5V. But the only difference between the two is that either 3.3V or 5V is connected to VCCIO. Since using 3.3V on VCCIO does not affect the maximum input voltage then I would be able to use a +5V system to send and probably receive data too. This means the 3.3V version would be much more universal than the 5V version. (because I don't want to use two boards)
