VNC2 Vinculum-II Programmable USB 2.0 Host

FTDI announces their 2nd generation of the Vinculum family USB host/slave controller devices. 

The VNC2 is a programmable dual USB 2.0 full speed Host/ Slave system on chip (SOC) controller which builds on, and enhances, the capacities and functionality of the VNC1L, the initial member of FTDI’s Vinculum family.  This has been achieved while reducing the device cost as well as introducing the capability for designers to develop their own application firmware and programme the host controller themselves.

The VNC2 boasts a powerful 16-bit MCU core with 256KB Flash, 16KB RAM and comes with a fully supported software development tool suite which is wrapped up in a GUI Integrated Design Environment (IDE). This is a free of charge and royalty free software development environment – which includes a compiler, driver, libraries, RTOS kernel, linker and debugger, allowing designers to fully utilise the increased memory and multitude of communication protocols handled by VNC2. The software development toolkit is based on the ‘C’ language and provides a comprehensive suite of object files to provide support for USB host functionality including USB Flash Drive (B.O.M.S.) storage, HID, USB COMMs class and FAT File functionality.

As you would expect the device features FTDI's award winning, tried and tested, firmware which is stored on-board in flash and can easily be updated ensuring your products are future proof.

Comprehensive Development Support

Custom PID service
For volume applications Alpha Micro can provide a Product Identifier (PID) under the FTDI "umbrella scheme" that can be used to personalise a design based on the FT232Bx so that your end user will see your product name in the Windows Install Wizard for extra brand awareness.

There is an added benefit that the driver is tagged to your hardware and cannot be used by other devices. This feature can only be used with FTDI chips, the Vendor ID (VID) must remain untouched. Please contact our sales team for more information on this facility.

Customers should use MPROG to program this feature and any other changes to the default settings within the EEPROM (which must be fitted if this feature is required). MPROG is free to use and performs the programming tasks over the USB.
