VNC1L - Vinculum USB Host Controller Device |
|
The VNC1L is the first
generation device of the FTDI Vinculum family of USB Host / Slave Controller
ICs, which are designed to deliver USB Host level interfacing capabilities
to embedded applications. The VNC1L features two independent USB Host /
Slave ports with an inbuilt 8/32-bit MCU processing core with 4KBytes of RAM
program memory and 64KBytes of embedded Flash memory for firmware storage.
The VNC1L supports UART, SPI slave and 8-bit parallel FIFO interfaces to
enable communication with external processing devices. Further the two USB
Ports on the VNC1L can be individually configured by firmware as Host or
Slave ports.
VNC1L can be programmed with FTDI’s in-house developed firmwares which supports a range of common USB device
classes, providing a cost effective, complete, ready-to-use USB interfacing
solution. Users do not need to license any USB software stacks or develop USB
drivers, indeed no knowledge of USB is required to use these devices. VNC1L
is ideal for implementing USB interfacing within existing applications
which do not already have USB, example applications include adding USB
Flash drive connectivity to a wide range of consumer and industrial
products.
