FT231X Full Speed USB to Full UART

USB DriverNote that this is the FT231X Full Speed USB to Full UART or ft231x usb uart driver and not that of the FT230X IC also on this website which are all manufactured by FTDI. The FT231X is also extensively used in adapter cables for computers as well as televisions and these have been listed below. It offers a compact bridge to full handshake UART interfaces. The IC makes it easy to add to a system design and it also offers the full FT-X series feature set as can be seen below. See also here.

FT231X Full Speed USB to Full UART

The baud rate is between 300 baud to 3 Mbaud and comes with a 512 byte receive buffer and 512 byte transmit buffer. The higher data throughput is facilitated by the buffer smoothing technology it uses. The IC has an integrated clock generator so no external clock is required. The USB protocol is handled by the the IC so no USB specific firmware programming will be required. This the ft231x usb uart driver.

You can also make use of the standard UART driver which you can find here. This is used by Connecmax in their Android-RS232 cable with FT231X IC. Their cable is for Android V3.1 or higher and connects the Android phone to the adapter. The IC is low powered (8mA) with a 2048 byte EEPROM for instruction storage. The application use is wide and includes the evaluation boards made by Shenzhen Ding Xin Yuan. See also rs232 max length as well as the ft230x basic uart driver as can be seen there.

The FT231X IC comes with the full features of FT-X series which have been added below and has been used for USB to RS232/RS422/RS485 converters as well as Digital Camera Interfaces connecting to a USB port. The features also allows for a Dedicated Charger Port (DCP) which makes charging the battery faster. The following features are included.

  • The FT231X is USB 2.0 Full Speed compatible;
  • There is also low USB bandwidth consumption;
  • The IC also has an internal 3.3V/1.8V LDO regulators;
  • There is also True 3.3V CMOS drive output and TTL input;
  • Note that it has an integrated +3.3V level converter for USB I/O;
  • It sports bus powered, self powered and high-power bus powered USB;
  • Battery Charger Detection;
  • Configurable CBUS I/O pins;
  • Royalty free drivers;
  • 512 byte receive buffer and 512 byte transmit buffer.

These are some of the features of the FT231X.

Note that there are Linux as well as Windows drivers which will allow you to make use of the IC in your evaluation board or your UART to USB products. You can search this website for other products which also use different versions of this IC.

Virtual COM Port Drivers (FTDI Drivers)

Firstly the Virtual COM port (VCP) drivers will ensure that the VCP appears as a USB device and will look as an additional COM port in your device manager available on the computer. The application software can then access the USB device via this virtual COM port. Finally these work for the FTDI devices. See also the FT232RL USB to Serial Adapter Driver.

Windows 10 & 11 Only 

The files includes the VCP (Virtual Com Port) and D2XX (driver)
