This TIAO USB Multi-Protocol adapter is powered by FTDI's flagship communication chip FT2232H.

It supports the following protocols: JTAG, SPI, I2C and serial.  With a 16-Bit Dual-Supply Bus Transceiver, this board can support voltage from 1.8v to 5.0v. It also uses a 3v to 5.5v multichannel RS232 Line driver/receiver for serial communication.

Supported softwares:

XC3SPROG - Windows / Linux console application to program CPLD/FPGAPackage Content:
