future technology devices international ltd. version 1.07 http://www.vinculum.co m vinculum VNC1L firmware - vdap ftdi usb slave device and usb flash disk interface with fxed monitor port the vinculum VNC1L-1a is the frst 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. ? ? preliminary - subject to change
vdap - vinculum VNC1L disk and peripheral interface firmware ? future technology devices international ltd. 2006 datasheet version 1.07 page 2 preliminary - subject to change 1 . o v e r v i e w 1.1 introduction this document describes the vdap version of vinculum VNC1L usb fash disk / usb device interface and command monitor frmware. vdap uses the VNC1Ls confgurable i/o interface fxed as the command monitor port. the i/o interface is confgured using a set of jumpers which pull up or pull down two of the VNC1L s pins. these jumpers are used to select between a uart interface, a parallel fifo interface, or a spi interface. the main function of this frmware is to allow an embedded device, based around the VNC1L, to communicate via the VNC1L-1as uart, parallel fifo or spi interface port with usb slave peripheral devices. these include usb flash disks, ftdis ft232, ft245 and ft2232 usb slave i.c. as well as devices that are printer or hid (human input device) compatible. other devices may also be supported if they have a suitable interface such as mobile phones. the vinculum VNC1L i.c. hardware specifcation is described separately in its own datasheet which is available from the vinculum websit e .
vdap - vinculum VNC1L disk and peripheral interface firmware ? future technology devices international ltd. 2006 datasheet version 1.07 page 3 preliminary - subject to change 2.1 vdap - vinculum disk and peripheral interface the vdap frmware is designed to allow an ftdi vinculum VNC1L device to act as an interface between a usb fash disk (or other usb mass storage class device) on usb port 2, and the VNC1L s i/o interface, or a suitable ftdi usb peripheral device on usb port 1. this frmware allows the VNC1Ls i/o interface to be externally confgured as a uart, parallel fifo or spi, using external jumpers. the device connected to the serial uart / parallel fifo / spi interface can issue commands which allow operations to be performed on the usb fash disk and / or usb slave device using the command set defned herein. the VNC1L port which is confgured to receive these commands is know as the command monitor port . in this case command monitor port is always the VNC1Ls i/o port, i.e. the serial uart / parallel fifo / spi interface. the current frmware supports all ftdi usb slave devices (eg. ft232r, ft245r, ft232b, ft245b and ft2232d) as well as giving support for printer class and hid class. a usb flash disk can only be used on port 2. 2.1.1 vdap command monitor port selection the vdap frmware always uses the VNC1Ls i/o port to act as the command monitor port. usb port 1 is a usb host port for connecting peripheral devices based on ftdi usb slave i.c. devices. usb port 2 is available as a usb fash disk interface (or other usb mass storage class device). the jumper confgurable uart / parallel fifo / spi interface port always acts as the command monitor port. the vdap frmware will use the device interface mode as selected on the acbus5 (pin 46) and acbus6 (pin 47) jumper pins as the command monitor port, i.e. serial uart, parallel fifo, or spi. the jumper circuit confguration shown in figure 2, below. this circuit will default to the uart interface if no jumper links are ftted. see table 1 for the port selection jumper pin confguration. usb port 1 is a usb host port for connecting peripheral devices based on ftdi usb slave i.c. devices. usb port 2 is available as a usb fash disk interface only (or other usb mass storage class device). the VNC1L uart / parallel fifo / spi to ft232 / ft245 interface works in command mode or data mode in a similar way to a modem. command mode is used to communicate with the VNC1L. data mode is used to communicate with the slave device on usb port 1 or 2. commands are provided to confgure both the VNC1L s uart and for an ftdi slave uart device on usb port 1 or 2. figure 2 - vdap firmware model vnc 1 l - 1 a p o r t a c p o r t b d p o r t b c central hardware core uart spi fifo interface select command monitor monitor is via i / f select select i / f mode for uart or spi or 245 p o r t a d firmware usb port 2 usb port 1 vcc 3 gnd interface select acbus 5 acbus 6 usb flash disk ft 232 / ft 245 based usb peripheral allow pass through from i / f port to usb port 1 check for command / data mode 47 k 47 k 2 . f i r m w a r e d e s c r i p t i o n table 2.1 - port selection jumper pins
