FTDI updates the Vinculum VNC1L host controller

The device can now operate between -40C and +85 C making it suitable for use in a wider range of appliances, including hand-held personal electronics devices such as personal media players, GPS navigation, cellular phones and digital cameras.

FTDI's VNC1L provides USB host interface and data transfer and supports popular device classes of mass storage, printer and human interface device (HID).

HID class devices typically include keyboards and mice.

When interfacing to Flash drives, VNC1L manages the file allocation table (FAT) structure by using a straightforward command set.

The device has eight and 32-bit custom processor cores, dual DMA controllers, 64k embedded flash and 4k internal Sram memory.

VNC1L features two independent USB 2.0 low/full speed host/slave ports.

These can be configured as UART, serial peripheral interface (Spi) or parallel Fifo interfaces.

VNC1L also has up to 28 general-purpose I/O (GPIO) pins available, depending on configuration.

The VNC1L is configured via the UART interface using a choice of free, downloadable firmware.

The VNC1L operates from a single +3.3V supply with +5V tolerant inputs.

The VNC1L has a low operational power requirement of 25mA and 2mA when in standby mode, making it perfect for portable battery-powered designs.
