FT4222H USB2.0 TO QUADSPI/I2C BRIDGE IC

1.3

Document No.: FT_001011 Clearance No.: FTDI#405

Application Examples

The following diagrams show the possible applications of the FT4222H. In Figure 8.1, a control IC with an

SPI slave interface but without a USB device interface can easily connect to USB by integrating the

FT4222H into the system. With FTDI’s mature and stable D2XX driver, and easy to use support library,

LibFT4222, the FT4222H can easily connect an application to USB.

Figure 8.1 Application Example 1

In Figure 8.2, a control IC with an SPI master interface but without a USB upstream port (USB device

interface) can easily connect to USB by integrating the FT4222H into the system. With a single SPI slave

interface defined in FT4222H and easy to use API defined in LibFT4222, it is easy to connect an

application to USB via FT4222H.
