 USB Device Solutions

With over 30 USB peripheral chips offered in 5 product families, designers can choose the device which best matches their system need. FTDI Chip devices are aimed at full, high, and super speed solutions.

 SuperSpeed USB3.0 USB Bridge Devices

FT60x Series:  Enabling faster and higher volume data transfers than ever before, the FT60x is the first SuperSpeed USB3.0 series from FTDI Chip that offers USB access to a wider range of data intensive imaging and data acquisition applications. The series incorporates two devices - the FT600 and FT601, which function as SuperSpeed USB3.0 to FIFO bridges, providing up to 5Gbps of bandwidth. The FT600 comes in a 56-pin QFN package and has a 16-bit wide FIFO bus interface, while the FT601 is provided in a 76-pin package and has a 32-bit wide FIFO bus interface. Both chips support up to 8 endpoints, with 2 additional communication endpoints, allowing for up to 4 data IN and 4 data OUT channels to be created with double buffering of up to 4kByte length for IN and 4kByte for OUT. FTDI Chip SuperSpeed Devices:

  • FT600 - 56-pin QFN package and has a 16-bit wide FIFO bus interface
  • FT601- provided in a 76-pin package and has a 32-bit wide FIFO bus interface


 Hi-Speed USB 2.0 Bridge Devices

H Series: fast, flexible, multi-channel USB bridges. In addition to data rates these devices offer (up to 40Mbytes/s) when compared to full speed solutions, the Hi-Speed series also offer a range of multi-channel interfacing; The benefits of a multi-channel bridge is that the system BOM is reduced by taking away the need for a USB hub chip. Additionally, each channel of the device appears to the host PC as a separate device, enabling each channel to be independently configured for different modes e.g. UART, MPSSE or FIFO and with different parameters such as 4 UARTS all operating with different baud rates. FTDI Chip Hi-Speed devices:

  • FT232H - Hi-Speed Single Channel USB UART/FIFO IC
  • FT2232H -Hi-Speed Dual USB UART/FIFO IC
  • FT4232H - Hi-Speed Quad USB UART IC
  • FT4222H - USB 2.0 to Quad SPI / I2C Bridge IC


 Full Speed  Bridge Devices
  • X Chip series: optimised for small footprint, low power and battery charger detection, the X-chip series for full  speed USB bridge solutions offers the widest range of interface options, all backed up with robust driver support on Windows, Linux, MAC OSX and WinCE.
  • R Chip series: optimised for minimal external components on a PCB design, the R Chip series offers a highly integrated solution combining USB protocol handling, internal clock control and EEPROM capabilities in one IC package
  • BL and D Chip series: an original, robust and market hardened solution, this series offers IO levels 3.3V to 5V, typical 25mA operating current, internal data buffering and extended temperature range
  • FT12 series: fully configurable Full Speed USB Device Controller series to add to any class of USB device support to MCUs.


 USB Host Solutions

As mobility accelerates, the need for host support in tablets, handsets and consumer equipment becomes critical to enable USB connections. With this in mind, we have a range of USB host solutions with a focus on Android Open Accessories (AOA), add-on USB host capability for USB 2.0 Hi-Speed, and continued support for system level solutions that include USB technology.


VNC2: 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 Vinculum Software Tool Suite, which provides an easy to use ‘C’ based development environment to enable user firmware development. Alternatively, the designer can configure VNC2 with one of the many precompiled 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.


VNC1L: The VNC1L is the first generation device of the FTDI Vinculum family of USB Host / Slave Controller ICs, which are designed to deliver USB Host level interfacing capabilities to embedded applications. The VNC1L features two independent USB Host / Slave ports with an inbuilt 8/32-bit MCU processing core with 4KBytes of RAM program memory and 64KBytes of embedded Flash memory for firmware storage. The VNC1L supports UART, SPI slave and 8-bit parallel FIFO interfaces to enable communication with external processing devices. Further the two USB Ports on the VNC1L can be individually configured by firmware as Host or Slave ports.

VNC1L can be programmed with FTDI’s in-house developed firmwares which supports a range of common USB device classes, providing a cost effective, complete, ready-to-use USB interfacing solution. Users do not need to license any USB software stacks or develop USB drivers, indeed no knowledge of USB is required to use these devices. VNC1L is ideal for implementing USB interfacing within existing applications which do not already have USB, example applications include adding USB Flash drive connectivity to a wide range of consumer and industrial products.


 Android Host (FT311D/FT312D)

The FT311D IC is designed to specifically host Android platforms that support Android Open Accessories (AOA) mode (Android 3.1 onwards). This chip will enumerate to provide a bridge to a variety of platforms selectable from 3 GPIO lines. The interfaces include GPIO, UART, PWM, I2C Master, SPI Master and SPI Slave, while the FT312D provides a UART interface. Packaged in 32-pin QFN or LQFP options, the devices offer a small, reliable bridge to allow Android devices such as mobile phones or tablets to communicate with peripheral hardware over USB.  The device does not require any drivers to be loaded on the Android platform and draws no power from the Android USB port, as the device is the USB host. To support this chip, we offer a development kit and GPIO interface board to jump-start engineers' designs and provide easy access and integration into users' end systems. With this fixed function, bridge host chip, designers can quickly and easily add USB functionality into products and connect to the expanding Android ecosystem.
