VNC2-48L1C - USB Vinculum-II Dual Host/Device Controller IC, 48-pin LQFP
The Vinculum-II VNC2-48L1C 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.
VNC2-48L1C features:
- USB speed: Full Speed (12MBps)
- Interfaces: FIFO, SPI, USB, UART
- USB transfer modes: Bulk, Isochronous, Interrupt
- Package: 48-pin LQFP
- I/O voltage: 3.3V
- Virtual COM port: No
- USB host: Yes
- Channels: 2
- USB Class: Various
- Operating temperature: -40°C to +85°C
Also available as the VNC-48Q1C in a 48-pin QFN package.
N.B. VNC2 devices are supplied unprogrammed.
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. Or alternatively, the designer can configure VNC2 with one of the many pre-compiled ROM files developed by FTDI to cover a range of popular interfaces. These are described at Precompiled Firmware. The VNC2 offers a complete USB system solution in a single IC.
