FTDI Chip develops innovative silicon solutions that enhance interaction with today’s technology. When a designer needs to add a USB port, rest assured that FTDI Chip has a full range of USB solutions to get the job done.
Universal Serial Bus (USB) is now established as the de-facto interface for connecting systems with a reliable, low-cost digital link. USB has expanded beyond PC usage, and can now be found in all market segments, including Industrial, Medical, Consumer, Communications, Networking and many more. Enabling designers to implement USB quickly into a design, FTDI Chip provides total solutions including silicon chips, development tools, application notes, and software support. Expertise in USB bridges provides seamless integration for a variety of interfaces such as UART, FIFO, I2C, SPI, PWM and GPIO, where the bridge converts the signalling and protocol from the selected interface to USB. USB solutions are delivered in packages as small as 10 pin DFN (3x3mm) or as modules that can be inserted into boards for development and production or in cables that bridge USB to numerous interfaces.
Whenever your development or product needs USB, check out FTDI Chip for complete solutions that can shorten your design time whilst providing robust system implementations, and realise how we make design easy.
The FTDI chips implement the USB protocol stack. The responsibility of this hardware is to tell your PC what it is (using some identification information) such that your computer can load the right driver for it, and also to manage the data transactions with the PC there-on after – look up USB endpoints for a better explanation of these processes.
Once those drivers are loaded, this would specify a command set that your PC can use to query the chip. This hardware takes care of one side of the equation (communication with your PC). The other side of it would be some dedicated hardware to manage the UART protocol which includes logic, buffers and line drivers and the sorts. The command set mentioned earlier would be used to read from or write to the UART hardware. It should probably be mentioned that USB devices are polled by the PC, so in instances where you are using code which is event based, your PC is actually doing some polling to determine that new data has arrived – this may be different than a native serial port, I wouldn’t know.
The above logic can be implemented either as a dedicated ASIC or by using a stripped down microcontroller core which executes firmware on ROM. If it is indeed a microcontroller core, then I imagine the UART is connected to it as a peripheral.
The FTDI cable is a USB to Serial (TTL level) converter which allows for a simple way to connect TTL interface devices to USB. The I/O pins of this FTDI cable are configured to operate at 5V.
The FTDI cable is designed around an FT232RQ, which is housed in a USB A connector. The other side of the cable is terminated with a 0.1″ pitch, 6-pin connector with the following pinout: RTS, RX, TX, 5V, CTS, GND (RTS is the green cable and GND is black).
This cable has the same pinout and functionality as our FTDI Basic Breakout board; you can use it to program your Arduino Pro, Pro Mini and Lilypad. For use with those boards, align the black and green wires of the FTDI cable with the ‘BLK’ and ‘GRN’ labels on the PCB.
There are pros and cons to the FTDI Cable vs the FTDI Basic. The FTDI Basic has great LED indicators, but requires a Mini-B cable. The FTDI Cable is well protected against the elements, but is large and cannot be embedded into a project as easily. The FTDI Basic uses DTR to cause a hardware reset where the FTDI cable uses the RTS signal.
