FT240XQ-R Integrated Circuits (ICs)

FT240XQ-R Application Field and Working Principle

Introduction

FT240XQ-R is an interface-controller which can be used to exchange data between USB and I2C/SPI/GPIO devices. It is a USB to parallel bus bridge set and generally utilized for connecting USB to the I2C bus, SPI bus, and GPIO. It appears as a RS-232 serial communications port on the PC.

Application Field

FT240XQ-R can be used for many types of engineering and applications. For example, it can be used for remote control of various I2C Slave devices or for peripheral interfaces for USB to SPI, I2C or GPIO control programs. It can also be utilized in reading temperature and humidity levels from sensor devices. FT240XQ-R can be applied in applications like data acquisition and acquisition and control systems, robotic control, network management, environmental monitoring, and more.

Working Principle

The working principle of FT240XQ-R is to use FTDI\'s FTD2XX USB drivers to provide a bidirectional transmit and receive serial port to allow data exchange between USB and I2C/SPI/GPIO devices. FTDI\'s FTD2XX USB drivers can be divided into two main parts, the hardware interface and the software driver. The hardware interface of FTDI’s FTD2XX USB drivers supports the I2C, SPI and GPIO interface protocol. The FTDI FTD2XX USB driver works as the communication bridge between the PC and the FT240XQ-R interface controller. The FTDI FTD2XX USB driver also provides the host-side control of the FT240XQ-R interface controller, such as setting the configuration word, resetting the chip, enumeration and more.

Conclusion

To sum up, FT240XQ-R is an interface-controller which is used to exchange data between USB and I2C/SPI/GPIO devices, based on FTDI\'s FTD2XX USB driver. It has is applied in a wide range of applications, such as data acquisition and control systems, robotic control, network management, and environmental monitoring. Moreover, the working principle of FT240XQ-R relies on FTDI\'s FTD2XX USB driver which provides a bidirectional transmit and receive serial port to allow data exchange.
