FT4232H Configuration
The V2-EVAL board features a FT4232H, a high speed USB to quad channel UART / serial converter
device. The device is primarily featured to provide a connection from the board to a PC host via the
onboard USB type B connector. Each of the four channels on the FT4232H device are used to provide a
separate functions on the V2-EVAL board.
The functions of the FT4232H include:
Channel A – UART interface. The FT4232H provides USB to UART conversion to allow a PC / USB
host PC to communicate with the VNC2, via the UART interface.
Channel B – Debug interface control. Enable software tool chain connectivity to the VNC2 debug
interface via the the USB type B connector on the board.
Channel C - Provide a UART data „sniffer‟ interface allowing inputs to the VNC2 UART interface to
be displayed on the host PC software.
Channel D – Device control. I/O pins are used to control the onboard multiplexer. The
multiplexer allows different interfaces to drive the VNC2 UART interface as well as the VNC2
PROG# and RESET# pins.
