geekmaster, i want to use this chip (i have it) :
This is the datasheet of the chip
http://www.sparkfun.com/datasheets/IC/FT232R_v104.pdf
Please have a look at page 7.
By this information I need two levels of voltage 3.3V for Pin no. 20 to power up the circuit. and another voltage of 1.8V for Pin no. 4 for output levels.
Do you think it should work?
