    ez-usb FX2LP IO Standard


      I'm trying to interface a Cypress EZ-USB FX2LP to an Altera FPGA and I was wondering what standard the IOs (PA,PB,PC,PD,PE) of the Cypress chip are? (i.e. CMOS 3.3V, open drain, etc.) We are trying to determine what voltage to drive the FPGA IO banks with, and if pull-up resistors are required or not.
