Document No.: FT_000138 Clearance No.: FTDI#143
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 withVDAP 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 andthe 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.
