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.

The VNC1L is a single chip embedded
dual USB host controller with the
following advanced features:
Two independent USB 2.0 Low-speed/Fullspeed
USB host ports.
Individual ports can be configured as host or
slave.
Configurable options to interface to external
Command Monitor via either UART, FIFO or
SPI slave interface.
Entire USB protocol handled on the chip.
Integrated pull-up and pull-down resistors.
Integrated FTDI proprietary, 8/32-bit
embedded MCU processor core -Vinculum
MCU (VMCU) - using “enhanced CISC”
technology.
Integrated, reconfigurable, 64k bytes of
embedded Flash (E-FLASH) memory to store
firmware. 4k bytes data RAM.
Field upgradeable firmware over UART or
USB.
Integrated Numeric Co-Processor (NCP)
enhances 32 bit arithmetic speeds.
Twin DMA controllers (one per USB interface)
provide hardware acceleration of data transfer
from USB to external IO bus.
Operational configuration via a choice of free,
downloadable firmware – no external software
control required.
Four fully configurable data and control I/O
buses providing up to 28 pins of general
purpose I/O.
Integrated firmware allows read from and write
to FAT format USB Flash keys.
Supports bus powered, self powered and highpower
bus powered USB configurations.
Programmable via UART interface.
+3.3V single supply operation with 5V safe
inputs.
Low power operation (25mA operational, 2mA
in standby).
-40°C to +85°C extended operating
temperature range.
Available in compact Pb-free 48 Pin LQFP
package (RoHS compliant).
