Vinculum VNC1L
Firmware - VDAP
FTDI USB Slave Device and USB Flash Disk
Interface with fixed Monitor Port
The Vinculum VNC1L-1A is the first of F.T.D.I.’s Vinculum family of Embedded USB host controller integrated circuit
devices. Not only is it able to handle the USB Host Interface, and data transfer functions but owing to the inbuilt MCU
and embedded Flash memory, Vinculum can encapsulate the USB device classes as well. When interfacing to mass
storage devices such as USB Flash drives, Vinculum also transparently handles the FAT File structure communicating
via UART, SPI or parallel FIFO interfaces via a simple to implement command set. Vinculum provides a new cost
effective solution for providing USB Host capability into products that previously did not have the hardware resources
available.
The VNC1L-1A is available in Pb-free (RoHS compliant) compact 48-Lead LQFP package.

3. Communicating to a USB Slave Device
Connect And Disconnect
Page
When a device is attached to one of the USB ports a message will be sent to monitor port saying :
Device Detected P1
Or
Device Detected P2
When one is removed from a USB port a message will be sent to monitor port saying :
Device Removed P1
Or
Device Removed P2
Query Port 1 and Query Port 2 Commands
To query the device there are new commands
available – ‘QP1’ and ‘QP2’. These will tell you all
the interfaces types available on port 1 and port 2
respectively.

File operations
‘RD’<sp> <name><cr>
$04,$20,<name> $0D
Read file <name>
‘RDF’<sp> <size in hex(4 bytes
MSB first) ><cr>
‘DLF’<sp> <name><cr>
$0B,$20,size in hex(4 bytes) ,
$0D
$07,$20,<name> $0D
Reads the data of <size in hex(4
bytes) > from the current open file.
Delete file <name>
‘WRF’<sp> <size in hex(4 bytes
MSB first) ><cr> <data bytes of
size><cr>
$08,$20,size in hex(4 bytes) ,
$0D $data,$0D
Writes the data of <size in hex(4
bytes) > to the end of the current
open file.
‘OPW’<sp> <name><cr>
$09,$20, <name>,$0D
Opens a file for writing to with
‘WRF’
‘OPR’<sp> <name><cr>
$0E,$20, <name>,$0D
Opens a file for reading to with
‘RDF’
‘CLF’<sp> <name><cr>
$0A,$20, <name>,$0D
Closes a file for writing.
‘REN’<sp> <orig name> <sp>
<new name><cr>
$0C,$20, <orig name>,$20, <new Rename a file or directory
name> <cr>
‘FS’<cr>
$12,$0D
Returns free space in bytes on
disk. For disks of over 4 GBytes
in size this will return $FFFFFFFF
if more than 4 GByte available.
Otherwise use ‘FSE’ command
‘FSE’<cr>
$93,$0D
<free space in hex(6 bytes) LSB
first> $0D
‘SEK’<sp><offset in hex(4 bytes
MSB first) ><cr>
$28,$0D
Seek to an offset within the file
Commands for UART monitor mode only
‘SBD’<sp><divisor (3 bytes) LSB $14, $20,divisor (3 bytes) LSB
first ><cr>
first >,$0D
Set Baud Rate (See Baud Rate
Table)
Power Management Commands
‘SUD’<cr>
$15,$0D
Suspend the disk when not in use
to conserve power. The disk will
be woken up automatically the
next time a disk command is sent
to it.
‘WKD’<cr>
$16,$0D
Wake Disk and do not put it into
suspend when not in use.
‘SUM’<cr>
$17,$0D
Suspend Monitor and stop clocks
Commands to FT232 / FT245 / FT2232 on USB Port 1 or 2
‘FBD’<sp><divisor(3 bytes )LSB
first><cr>
$18,$20,<divisor (3 bytes) LSB
first>$0D
Set baud rate (See baud rate
table 7)
‘FMC’<sp><value (2 bytes) ><cr> $19, $20,<value (2 bytes)>,$0D
Set modem control for RTS/DTR
(See table 8)
‘FSD’<sp><value (2 bytes) LSB
first ><cr>
$1A, $20,value (2 bytes)LSB first Set data characteristics (See table
>,$0D
9)
‘FFC’<sp><value (1 byte)><cr> $1B, $20,value (1 byte),$0D
Set flow control (See table 10)
‘FGM’<cr>
$1C,$0D
Get modem status (See table 8)
‘FSL<sp><value (1 bytes)><cr> $22, $20,value (1 bytes),$0D
Set Latency Timer
This will send back the entire
file in binary to the monitor. The
size should first be found by
using the ‘DIR’ <sp> <name>
<cr> command so that the ex-
pected number of bytes is known.
<prompt>$0D
This will send back the requested
amount of data to the monitor.
<prompt>$0D
This will delete the file from the
current directory and free up the
FAT sectors. <prompt>$0D
