Vinculum-II Embedded Dual USB Host Controller IC  
Version 1.7  
Document No.: FT_000138 Clearance No.: FTDI#143  
5.2 I/O Multiplexer Configuration  
The VNC2 I/O Multiplexer allows signals to be routed to different pins on the device. To simplify the  
routing of signals, the VNC2 RTOS provides an utility (IOMux) to configure the I/O Multiplexer as the  
designer requires.  
The IOMux is fully integrated into the VNC2 IDE (Integrated development  
Environment) which is available to download: Vinculum-II Toolchain. A screenshot of the IOMux utility is  
shown in figure 5.5 below.  
The IOMux utility user guide is available to download: VINCULUM-II IO_Mux Configuration Utility User  
Guide  
The following tables provide a lookup guide to determine what signals are available and the list of pins  
that can be used:  
Table 5.2 Group 0  
Table 5.3 Group 1  
Table 5.4 Group 2  
Table 5.5 Group 3  
Each VNC2 has a default state of IOBUS signals following a hard reset. The number of I/O pins available  
is determined by the package size:  
Package 32pin (LQFP & QFN)- Twelve I/O pins IOBUS0 to IOBUS11  
Package 48pin (LQFP & QFN)- Twenty eight I/O pins IOBUS0 to IOBUS27  
Package 64pin (LQFP & QFN)- Forty-four I/O pins IOBUS0 to IOBUS43  
Section 3.12 shows the default signal settings for all three package sizes.
