C232HD USB 2.0 HI-SPEED TO UART CABLE Datasheet Version 1.3 Document No.: FT_000430 Clearance No.: FTDI# 222 1 Description The USB 2.0 Hi-Speed to UART cable incorporates FTDI’s FT232H USB to UART interface IC device which handles all the USB signalling and protocols. The cable provides a fast, simple way to connect devices with 3.3 volt digital interfaces to USB. The C232HD UART cable contains a small internal electronic circuit board, utilising the FT232H, which is encapsulated into the USB connector end of the cable. The FT232H is a single channel USB 2.0 Hi-Speed (480Mb/s) to UART IC. For full details, features and enhancement descriptions please refer to the FT232H datasheet. The digital interface of the cable is made up of ten individual wires which are terminated with single pole connectors which can be connected next to each other on a male header. The cables digital interface logic is 3.3 volts. The USB side of the cable is USB powered and is USB 2.0 Hi-Speed compatible. The cable is 1.8m long and supports a data transfer rate up to 12 Mbaud. The C232HD UART cable requires USB drivers, available free from http://www.ftdichip.com , which are used to make the FT232H in the cable appear as a virtual COM port (VCP). This then allows the user to communicate with the USB interface via a standard PC serial emulation port (for example TTY). Another FTDI USB driver, the D2XX, is used with application software to directly access the FT232H on the cable though a DLL. This is illustrated in the Figure 1-1.

This cable contains an EEPROM which contains the USB configuration descriptors for that device. When the cable is plugged into a PC or a USB reset is performed, the PC will read these descriptors. The default values stored into the internal EEPROM are defined in the following table. Parameter Value Notes USB Vendor ID (VID) 0403h FTDI default VID (hex) USB Product UD (PID) 6014h FTDI default PID (hex) Serial Number Enabled? Yes A unique serial number is generated and Serial Number See Note programmed into the EEPROM during device final test. Enabling this option will make the device pull down Pull down I/O Pins in USB Disabled on the UART interface lines when the power is shut Suspend off (PWREN# is high). Manufacturer Name FTDI Product description depends on the cable. The following lists the Product descriptions for each different cable.
