8.4 Precompiled Firmware

VNC2 can be programmed with various pre-compiled firmware profiles to allow a designer to easily

change the functionality of the chip.

The following pre-compiled ROM files are currently available:



V2DAP firmware: USB Host for single Flash Disk and general purpose USB peripherals.

Selectable UART, FIFO or SPI interface command monitor. Offers a migration path from VNC1L

designs with VDAP firmware.



V2DPS firmware: USB Host for single Flash Disk and general purpose USB peripherals and USB

peripheral emulating a FT232 on a Host computer. Offers a migration path for VNC1L designs

with VDPS.



V2F2F firmware: USB Host for two Flash Disks with file copy functions. Offers a migration path

for VNC1L designs with VF2F firmware.



CDC Modem Sample Application: Demonstrates connection of a CDC device to USB Port 1 by

establishing a link between the CDC device and the UART of the VNC2.



USBHost FT232 UART Echo Sample Application: Demonstrates emulation of a FTDI FT232

device on USB Port 1. Data is looped back.

Designers are advised to refer to the FTDI website for the most current details on available Firmware.
