Vinculum II

VNC2 - Vinculum-II Programmable USB 2.0 Host

Vinculum-II (VNC2) is FTDI’s 2nd generation of USB Host / Slave controllers. The device features a powerful 16-bit MCU core, with embedded 256KB Flash and 16KB RAM memory. The device supports a range of flexible interfaces including UART, SPI, FIFO and PWM. The complete USB protocol data processing is handled entirely by hardware resources within the device freeing up processing resources for user developed applications.

The VNC2 is a fully programmable device and is supported with the new Vinculum Software Tool Suite, which provides an easy to use ‘C’ based development environment to enable user firmware development. The VNC2 offers a complete USB system solution in a single IC.
