Product Summary
The VNC1L-1A is a single chip embedded dual USB host controller. The VNC1L-1A is the first of FTDI.s Vinculum family of Embedded USB host controller integrated circuit devices. Vinculum can also encapsulate certain USB device classes handling the USB Host Interface and data transfer functions using the in built MCU and embedded Flash memory. When interfacing to mass storage devices, such as USB Flash drives, Vinculum transparently handles the FAT File Structure using a simple to implement command set. Vinculum provides a cost effective solution for introducing USB host capability into products that previously did not have the hardware resources to do so. The VNC1L-1A has a Combined Interface which interfaces a controlling application with the Command Monitor. The combined interfaces are UART, Parallel FIFO and SPI.
Parametrics
VNC1L-1A absolute maximum ratings: (1) Ambient Temperature (Power Applied): －40°C to 85°C Degrees C.; (2) Vcc Supply Voltage: 0 to +3.6 V; (3) DC Input Voltage － USBDP and USBDM: －0.5 to +(Vcc +0.5)V; (4) DC Input Voltage － High Impedance Bidirectionals: －0.5 to+5.00 V; (5) DC Input Voltage － All other Inputs: －0.5 to +(Vcc +0.5)V; (6) DC Output Current － Outputs: 8mA; (7) DC Output Current － Low Impedance Bidirectionals: 8mA; (8) Power Dissipation (Vcc = 3.6V): 250mW.
Features
VNC1L-1A features: (1) Two independent USB 2.0 Low speed/Full speed 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; (2) Entire USB protocol handled on the chip; (3) Integrated pull up and pull down resistors; (4) Integrated firmware allows read from and write to FAT format USB Flash keys; (5) Supports bus powered, self powered and high power bus powered USB configurations; (6) Programmable via UART interface.
