FTDI Vinculum-II Embedded Dual USB Host Controller
|
The
FTDI Vinculum-II
(VNC2)
Embedded Dual USB Host Controller IC
represents the second generation of
FTDI USB Host
devices. The
Vinculum-II
CPU is dramatically upgraded from the previous VNC1L device, greatly increasing the processing power. This
FTDI Embedded Dual USB Host Controller
features a powerful 16-bit MCU core with 256KB Flash and 16KB RAM memory. The
Vinculum-II
is a complete
USB
system solution that 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. This fully programmable
FTDI Embedded Dual Host Controller
is supported with the new
Vinculum
Software Tool Suite, which provides an easy to use C based development environment to enable user firmware development.
